I bought my 4.6 new in 1999. I have really enjoyed it all this time. I've had it serviced regularly by the dealer since Day One. The mileage is now up to over 90M and I'm having some trouble. It seems the EAS has broken and needs replacing. I just got a call from the dealer and they want somewhere near $4,000 or so to do it. Also, the Heat/AC unit is having trouble blowing where it needs to. It heats and cools just fine, just not where it always should, at least on the passenger side. They want about $2,100 to fix that. All in all they just called with about $6M in estimates.
Absent these two problems the car runs great and is still a pleasure to drive. Drives as good as they day I got it. I'm just hesitant to put this kind of money into a car whose book value isn't substantially more than that. If I were to sell it in this condition, do any you have any idea what it might be worth??

Gosh if that is all that you are having trouble with I'd put a spring kit on it. And I'd find an independent for the heating and cooling issues.

You'll come out with less cost and you'll never have to fix the EAS again.

Money doesn't grow on trees at my house so I do a lot of work myself. It always amazes me the cost for dealer repairs. I enjoy the work mostly and my time is technically free.

I know everyone isn't into the mechanical like I am and I have my limits where I take it to someone else. For me I love my Rover and will continue to fix it until it gives up entirely on me.

Hope you find peace with it.

I'm in agreement with Okie regarding changing out the EAS for a set of conventional coil springs. Both Rovers North, and Atlantic British offer a complete kit to do the job. It's about a 2 1/2 wrench job, and they offer a pretty good set of instructions with the kit.

The climate control problems are as common as dirt on P38A Rangies. Your blend motors are shot. They aren't so cheap, but the real cost is in the labor, it means dissassembling the entire dash. If you're all thumbs, cut 2 off each hand and dive in. Unless my dealer can actually prove he has pictures of me and his pet sheep, I'll never pay the kind of money they want.

I just did quite a few repairs on my 96 4.0, did all the work myself:

New Rear airspring bellow, new EAS pump, re oringed the EAS valve block,
New Trans and Oil cooler lines, New pAss fan motor, new dash bulbs, new fuse box, new rear hatch struts, changed all fluids, new cd player, replaced Heater orings,

The local independant did a reset on the EAS for me and said I should convert to springs as well...I just like the EAS...Wife is a realtor and needs it to lower for the olderly clients she has.

The closest dealer is 300 miles away, so for me to go there is a dy or two off and a drive up there to get gouged...Tried a few things on my own and all went well, So I am doing everthing I can to save Money

see if you can get a report from them as to what is actually wrong with the EAS..there are parts available for repairs..like O-Rings, I spent 20.00 on new rings and Dealer wanted to replace valve block for 1,500.00, wanted close to 400.00 for a new rear airspring, I bought a below only for 98 with lifetime warranty

theres alot you can do yourself and save alot of money
www.rangerovers.net has alot of repair write ups and how to's, lists of parts suppliers and there are lists like this one that has many subscribers that will do what they can to help you out

six grand, jeez at our place anything over a grand in EAS just gets an alternative for coil springs. We dont want to waste the time trying to fix a broken part when it blows ten miles down the road.

and two grand for a heater fix.

what are they actually quoting you. is it a problem with say a blend door motors or an actual module. cause if thats your problem then being a module then yes its not absurd. but anything else is pushing it.

get a second opinion.

You would be amazed at the stories we hear about repair estimates. Just remember a lot of times if something was working fine and all of a sudden it quits it is usually something simple, like a loose wire.
I have bought several rovers where the wiring harness was loose at the connectors. Threw off all sorts of codes. Dealer was overwhelmed with repairs. I just checked connections and fixed the problem.
Wouldn't you hate to be the guy on the other end who use to own the truck.

O-Rings

Rover4_0 - pm'd you about o-rings.

Can anyone explain how hard it is to replace the O-Rings on the valve block? My dealer said the #2 valve is bad and it would be $1200 to replace the whole thing. I have intermittant sagging and all bags are working well.

Where can you get the O-Rings from? Any details would be greatly appreciated.

Thanks,

Joe

If the valve is bad, an o-ring won't fix it. We do spring conversions on P38 Rangies all the time- $795 for the parts and an afternoon of work- and without fail the customers always say they like the ride with the coils better.

The blend doors are a PITA to work on- if it needs a module that's easier, lots of junked P38's to get used parts from. Usually it's the blend doors. On one, we just parked the doors so the air went to feet and windshield and they were happy with it fixed on that setting...

Either that or sell me the truck cheap and I'll fix it and keep it. :D

Ditch the EAS...that system sucks..My parents have had a lot of troubles with theirs.....next problem it has we are putting coils in.... Atlantic British sells the conversion kit also...It's not too hard of a job...But give yourself a saturday and a few buddies to help.... The ride is really nice with the coils..there are different types so do a little research to find the kind of ride you like....As far has heat and cool..... that is a comon problem on the P38.....my parents have a different problem but same area.....I'd say blender motors..but that is a guess...My parent had theirs don not too long ago and it was $1000 for all of them and labor..I'd keep the truck but take it somewhere else such as a indepdent shop!!

If you are having intermittant sagging but the system still works (all 4 raise and lower) then you only have a leak. This can be repaired for less than $20 in o-rings. Dealers do not repair any of the parts, they will just replace with new. You can bascially rebuild the entire EAS system for about $500, which includes rebuilding the compressor, all new o-rings in the valve block and in all fittings, and all new air springs. Of that $500, $400 or so is for the springs, about $80 for the compressor rebuild kit, and about $20 for all the o-rings. I suggest you contact shupack on the rangerovers.net forums. He can supply the o-rings, compressor rebuild kit, and even rebuild your compressor and valve block if you wish him to. New bellows for the springs can be had from Arnott Industries

Your A/C problem is most likely blend motors. You can buy the set of 3 for about $150, and with some patience replace them yourself with the excellent writeup on rangerovers.net.

Body & Chassis Parts Range Rover 4.0 / 4.6 /P38A

Tailgate & Hood Struts
Tailgate Strut: Aftermarket replacements for the tailgate strut are available at SpeedyCarParts.com (click on "Rover" parts) for $27. I recently (October 2004) found it was even less at British Pacific (their part number ALR10050) for $24.25. I recently found (October 2004) that Atlantic British trumps all comers in this category with a price of $29.95 for the pair!!


Hood strut: The genuine part allows locking of the hood in the position and costs a lot -- well over $50. SpeedyCarParts.com have a low cost non-locking replacement for the hood strut for $26.24.


Grille:
I discovered that the genuine radiator grille is now available from Atlantic British for $189.


Rear View Mirror:
Paul Smail of Annapolis MD reports "I have twice replaced the auto-dimming mirror in my Range Rover. A couple of years ago I purchased a comparable replacement directly from Donnelly (OE manufacturer) after being quoted nearly $700 for a genuine replacement. The ersatz replacement cost around $250 and was supposedly better constructed, using some sort of gel photochromic matrix rather than the liquid in the original mirror, plus it had a nifty compass! Notwithstanding this new technology, the replacement mirror waited just until it was out of warrantly to fail. Have since purchased a genuine parts replacement from The Rover Connection out in Utah for a price comparable to that of a Magna-Donnelly replacement. The Rover Connection also have mirrors for other model Land Rovers in the $250 price range.

Wing/Fender:
The easily-damaged front fender or wing is now available from aftermarket suppliers such as Atlantic British, who have it in stock for $459.95.


Braking System Range Rover 4.0 / 4.6 /P38A

ABS Accumulator:
Most suppliers do not seem to list this part separately, but I did find it at Rovers North for $326. SpeedyCarParts.com (click on "Rover" parts) lists new units for $239 with free shipping. Recently, (October 2004) I found it at British Pacific (STC2784) for only $199.99!


ABS Pump:
This component is so expensive that most suppliers don't seem to even list it. I did find it at Rovers North for $1075, but the lowest price I have found so far is at British Pacific, who have it for $999.

Calipers & Caliper Repair Kits:
When the calipers start leaking, the new ones (especially for the front) cost over $300 each, or you can get rebuilt ones (eg Rovers North has them for about $141 each for the front ones, and partsamerica.com has them for about $135). Alternatively, you can easily rebuild them yourself, using an aftermarket caliper rebuild kit that includes all the seals -- I found one for the 4.0/4.6 at SpeedyCarParts.com (click on "Rover" parts) for only $41 for the front brakes and $29.97 for the rear. I also found one for the front brakes at British Pacific (STC1919) for $15.99, who also have rear kits (STC1909) for $26.95. Atlantic British does not have the front kits but has one for the rear for only $14!

Caliper Guide Pin Kits
A more common problem than worn out or leaking calipers is frozen caliper guide pins, which you will notice when you try to do a brake job. I shopped around and found Atlantic British has them for $28.95 (front axle set) and $26.95 (rear axle set) including new pins, rubber boots and special lubricant.

Pads:
Part Numbers: Front STC3685, Rear STC3684. Dealer Price (Oct 2004) approx $180 per axle set.
Atlantic British offers several aftermarket brake pad options from $44.95 to $130 for front pad sets and $32.95 to $100 for rear sets. British Pacific stocks the genuine front pads (SPF100460G) for $69.95 and the well-known Ferodo aftermarket brand for $44.95 (SPF100460). For the rear pads, they stock two options -- SPF100470F for $59.95 SPF100460P for $39.95.
The lowest prices from Rover aftermarket specialists for the front pads seem to be British Pacific (SPF100460) Ferodo brand pads and Atlantic British Lockheed brand pads (made in the UK) for $44.95.
For the rear pads, I thought the record was held by SpeedyCarParts.com (click on "Rover" parts) for Deluxe PBR brand pads for $35.78. (Their options for the front include $70 for Mintex and $96 for OEM Lucas pad sets). However, Atlantic British now (October 2004) offers the highly respected Lockheed brand rear pads for only $32.95!!
If you want to try a real generic part (not really advisable when it comes to brakes in my opinion!), you can try the Wagner rear pads I found at AutoPartsGIANT.com for $26.00 or the rebuilt "Wearever Silver" ones from partsamerica.com for $11.48 -- if you attempt this please let me know the results!!
Parking Brake Shoes:
I have not seen these listed in mail order catalogs but SpeedyCarParts.com (click on "Rover" parts) has them for $121 for a set with free shipping.


Rotors/Discs: The extra weight and speed of the 4.0/4.6 models is hard on brakes an they seem to wear out the rotors rapidly. The stock front brake rotors are $81 from Rovers North, but aftermarket units are now available. The lowest prices I have seen after searching many sources are the following:
Front: SpeedyCarParts.com (click on "Rover" parts) Brembo front vented discs for $65 each (their rear ones are $46). Atlantic British has aftermarket front rotors for $50.95.
Rear: Atlantic British has rear rotors for $41.95 each.

Climate Control Range Rover 4.0 / 4.6 /P38A

A/C Compressor & Clutch:
The compressor/clutch assembly is now about $500 from discount mail order houses such as Atlantic British, which is a bit lower than prices for the Classic equivalent. In October 2003, Alan Rawson reported finding a company in Abilene, TX that rebuilds compressor clutches and has a stock of other parts. Hancock Industries (http://www.hancockindustries.com/) sold Alan a rebuilt AC clutch for $110 (+$50 core). It turned out to be very easy to take the old one off his '96 4.6HSE and slip the new one on w/o disturbing the AC charge--it only took courage dealing with the unknown. They sell a complete (rebuilt?) compressor w/clutch for $250 ($75 core). The parts had no written instructions since they are intended for professional AC shops, but John, in the Hancock rebuild shop, was extremely helpful in explaining how the clutch was mounted and what to do in getting it off, how to set the air gap. I did find a generic replacement for the clutch bearing at partsamerica.com for $42.99 (retail cost given as $129).
Please email me if you find any other low cost generic replacement for the A/C compressor or parts thereof.


A/C Condenser Unit:
This is a very expensive item to replace. I found aftermarket versions of the condenser only at Atlantic British for $429.95, or the complete unit with fans for $949.95. SpeedyCarParts.com has the complete assembly (Valeo brand) with fans for only $772.94.


A/C Receiver/Drier:
I found this item for $119.95 from Atlantic British. I also found it (October 2004) in stock at SpeedyCarParts.com (click on "Rover" parts) for $83.97 with free shipping! If you wish to try a generic solution, the Ready Aire 4086 is listed for the 4.0/4.6 by partsamerica.com for only $61.99!


Climate Control Head Unit:
The control panel and ECU that is the mastermind of the 4.0/4.6 climate control system usually costs about $600 even at aftermarket parts suppliers I have searched. I was therefore pleasantly surprised to find it at Car Cannibal for only $395 exchange, for models with or without heated seats, whether the problem with yours is display readout failure or complete malfunction.

Expansion Valve:
Until recently I was never able to locate a low cost source for this part; it was not even listed in the catalogs I tried. The usual replacement part is about $180, but recently (October 2003) I finally found a generic replacement (Egelhof brand) for only $34.79 at SpeedyCarParts.com.


Blend/Flap Motors:
These motors that control air distribution from the heater body are a common failure item (see heater blend motor diagnosis and replacement page). Atlantic British stocks the set of three with the harness (STC3259) for $199. The lowest cost I have seen for them to date (October 2004) is at SpeedyCarParts.com where they have them for $175 (free shipping). The separate blend motor for the fresh air/recirc flaps (mounted to the blower motors behind the extreme left and right fasia vents) can be had for $109 at Atlantic British (STC3266). You should also be able to use this part to replace any single one of the other blend motors insteatd of all three, and splice the leads into the wiring harness.


Heater Core:
This component (STC3261) does not fail as readily as on the Classic, but eventually it does. Unfortunately it is a more expensive part than the old Classsic version. SpeedyCarParts.com has it for $369, and I found the genuine part available at Atlantic British for $339.95.


3-Way Pressure Switch:
This vital component (which attaches to the receiver/drier and makes sure the system pressure is within prescribed limits before it allows the compressor to be turned on) failed on mine (see A/C problems section) and the A/C blew hot air. I found you can now get a replacement at SpeedyCarParts.com for only $82.

Cooling System Range Rover 4.0 / 4.6 /P38A

Belt (Serpentine):
The lowest price I have seen for the serpentine belt (1995-98) after searching many catalogs and websites is $19.99 at British Pacific (ERR4460).
For 1999-02 models, the lowest price I have seen (October 2004) is $22.99 at British Pacific

Belt Tensioner Assembly:
This is a known weak point on the 4.0/4.6. The price of a replacement from Rovers North is now down to $81.52; this seems to be the lowest price currently available (October 2004) if shipping costs are not counted. SpeedyCarParts.com lists an replacement for $87 with free shipping, which would probably work out cheaper overall.

Expansion Tank Cap:
Atlantic British has these (ESR1480) for only $21.95, guaranteed to fit.


Fan Blades
I found these at SpeedyCarParts.com for only $103. Atlantic British lists an aftermarket design, slightly different from the original, for $79.95.


Hoses:
For the radiator top hose (usually the first to go as it is the hottest), aftermarket replacements average about $11. A Gates replacement part #20357 is listed at AutoPartsGIANT.com for $7.82. The lowest price I have ever seen (October 2004) is at Partsamerica.com which has a Drive-Rite brand generic replacement (curved, cut to fit) for $5.99!!


Radiator:
95-98 Models: I found new OEM and aftermarket radiators for 95-98 models (genuine part equivalent PCC106940 for VIN numbers to WA410481) at SpeedyCarParts.com (click on "Rover" parts) for $423 with free shipping. Radiator.com did offer a replacement for $445 but recently they changed their website and I find it too difficult to navigate. The lowest price I have been able to find after searching high and low is at Atlantic British who now list them (February 2005) for $349.95. (To find it, do a search for "radiator" under RR 4.0/4.6 in all categories or the engine category on their website).
99-02 Models: The radiator for the later Bosch engine models is part number PCC106850. SpeedyCarParts.com has them for $394.92 with free shipping, and the lowest cost source I have seen is British Pacific for $389.


Thermostat:
On 4.0/4.6 engines the thermostat is a large, expensive item in a separate housing with several hoses connected to it. After searching many sources (October 2004) I found the best deals at British Pacific which has them for $87.50, and at Atlantic British who have them for $79.95 plus shipping.


Viscous Fan Clutch:
As of October 2004 the cost of the 4.0/4.6 viscous fan clutch is $229 at Rovers North, who also sell an aftermarket versionn for $209. The best deal I can find for this part after searching multiple sources is at Atlantic British for $183.95.


Water Pump:
SpeedyCarParts.com (click on "Rover" parts) have these for $162 (free shipping). Atlantic British now lists an aftermarket water pump for the 4.0/4.6 for $155.
The lowest price I have seen to date is an A1 Cardone brand unit (try at your own risk -- let me know of your experience) for $148 with free shipping at ExpressAutoparts.com.
Update August 2004: The Rover Connection has just announced that they have water pumps for all 4.0/4.6 RR models for $89!!


Water Pump Gasket:
I found a British made generic replacement for this at SpeedyCarParts.com for only $6.52.


Water Temperature Sender:
This sensor that drives the temperature gauge is not as expensive as on early Classics. Aftermarket versions are available at reasonable prices; SpeedyCarParts.com (click on "Rover" parts) sells one for $22 (listed in their "Body Electrical" category, not Cooling System!).


Cruise Control Range Rover 4.0 / 4.6 /P38A

Vacuum Pump:
This item is a fairly expensive one to replace. Even at aftermarket suppliers like Atlantic British it is $404.95. However, I recently (October 2004) found a replacement at SpeedyCarParts.com (click on "Rover" parts) for $150.53 (Body Electrical parts category).


Electrical Range Rover 4.0 / 4.6 /P38A
Alternator:
New Alternators: Dealers charge anything up to $700 for new alternators. Rovers North has aftermarket "ProLine" versions now for $399, and SpeedyCarParts.com has brand new Marelli alternators for the 4.0/4.6 for $365.62. The lowest price I have found for new alternators is at British Pacific which offers new alternators for $314.99 (AMR4247 -- 1995 to mid 97) and $349 (AMR2938 -- mid 97 through 98). These two models seem to be interchangeable. The part for 1999 on is ERR5834, but aftermarket suppliers do not seem to offer it yet.


Rebuilt Alternators: The Rover Connection has these for $220 but with a rather massive $150 core charge! AutoPartsGIANT.com has several options for rebuilt units, with the lowest cost one being only $142! SpeedyCarParts.com (click on "Rover" parts) has rebuilt100 amp Bosch units for $220.86 (October 2004). Partsamerica.com lists an Autolite remanufactured alternator for $211.99.
The lowest price I have found for rebuilt alternators is $142 (free shipping) at AutoPartsGIANT.com, which also has a couple of other brands to choose from.

Battery:
Brian Weaver reports that the replacement battery for the 4.0/4.6 is an Interstate Commercial
battery, the 29H-VHD. It retails for $80.95. Here's a link to it at Interstate's website.


Fuse Box:
Unfortunately this is a failure item on the 4.0/4.6 (see the fusebox problem & repair page for ways you might be able to fix yours to avoid replacement). I recently found (Novemner 2004) that Import Parts Bin/Speedy Car Parts stock new fuse boxes for the 4.0/4.6 (1995-98) for $216.71 with free shipping. (Click on "Rover" parts -- body electrical). They also have the 1999 & up fusebox for $164.17 with free shipping. Atlantic British has replacements for prices nearly as low -- $224.95 for 1995-98 and $169.95 for the later Bosch controlled engines (1999 & up).


Headlight Bulbs:
Sylvania lists their part number 9003 for low beam replacement, (with 9003CB for an upgrade), and 9005 for the high beam. For the auxiliary headlights, they list the H3 55W bulb.
The 9003 (Wagner) is listed for $9.03 at ExpressAutoparts.com. and both the Sylvania 9003 and 9005 (high beam) are $8.49 at partsamerica.com. They also list a General Electric H155 high/low beam bulb for $7.59, among many other alternatives and upgrades.


Fog Lights:
H3 55W

Relays:
Most relays on the 4.0/4.6 are Siemens parts.


Starter Motor:
The costs of aftermarket and rebuilt starters for the 4.0/4.6 have come down recently (October 2003). The Rover Connection has them for $350.
The lowest pricse I have seen for new starters are at Atlantic British who have brand new ones for $199.95 plus shipping, and SpeedyCarParts.com who have new ones for $195.30 with free shipping. British Pacific has them (check with them whether new or rebuilt but I think they are new) for $189.00 plus shipping.
Rebuilt Bosch starters for the 4.0/4.6 by Orange County Alternator are available from AutoPartsGIANT.com for $206. Ampere Automotive brand rebuilt starters are available from ExpressAutoparts.com for $178.83. The lowest price I have seen for rebuilt ones is $145 from The Rover Connection (plus a core charge).



Engine Mechanical Range Rover 4.0 / 4.6 /P38A
Camshaft & Rocker Shaft Components:
SpeedyCarParts.com has camshafts for $233 with free shipping, cam followers for $11, rocker shafts for $78, and rockers for $7.

Engine Long Block:
I recently discovered that Car Cannibal offers complete rebuilt 4.6 engine long blocks including, if you wish, a mildly enhanced cam for more power and torque) for only $4,000.


Head Gaskets:
The 4.0/4.6 is unfortunately notorious for blowing head gaskets. I still recall talking to an owner of a brand new 2000 model who had just had this happen on his.The good news is that replacements, made by Elrin, the OEM supplier to Land Rover, are available for only $10 each at SpeedyCarParts.com! (Click on "Rover" parts). They also have a complete set of all required gaskets for a head gasket job for only $128.90! Head gaskets in all these sets are composite material with steel reinforced head bolt and cylinder bore holes.

Intake Manifold Gasket:
This is an item that has had to be replaced innumerable times at considerable expense on my 4.0SE. I recently found out that SpeedyCarParts.com (click on "Rover" parts) stocks the intake manifold valley gasket for only $11!

Main and Rod Bearings:
Aftermarket rod bearings are now available from Atlantic British for $84.95 per set. I found a British-made set of 4.0/4.6 rod bearings at SpeedyCarParts.com (click on "Rover" parts) for only $39. Their main bearings are $82 per set with free shipping.

Timing Chain:
An aftermarket timing chain is available from Atlantic British for $50. SpeedyCarParts.com (click on "Rover" parts) has it for $36. The timing cover gasket needed if you are doing this job is $10.84 from the same supplier.


Exhaust System Range Rover 4.0 / 4.6 /P38A

Catalytic Converters:
These are expensive items to replace, and all 4.0/4.6 models have a single piece Y pipe with both converters that comes as a single unit. The genuine part number is ESR4095 for model years through 97 (cost so high you are afraid to ask). With this in mind, Atlantic British developed their own replacement for this part using quality aftermarket cats and stainless steel pipes. This should last longer than the genuine part, and is priced at $699.95. The Rover Connection lists an aftermarket replacement for the Y pipe and cats for $550. SpeedyCarParts.com lists the combined Y pipe and converters in stock (49 state) for $504.67 (with free shipping, which is a significant factor on such a bulky item).
The lowest price I have seen to date is at Discount Converters Ltd of Houston, Texas, which lists a 49-state replacement part number ROVqq09 for the 4.0/4.6 that includes both left and right converters for $432.95 plus shipping, and a 50 state system for $489.95 plus shipping.

Complete Cat-Back Exhaust Systems:
I found a complete cat-back replacement exhaust system at Atlantic British for about $400 -- a savings even on discount aftermarket pricing for the separate items (see below). aftermarket Borla makes a performance enhancing exhaust system for the 4.0/4.6, available through Atlantic British for $799. Northwest Rover Performance is also working on a system for the 4.0/4.6. Note that these high performance systems can increase noise and resonance at certain speeds.

Mufflers, Center and Rear:


(For full details on replacement of the center and rear mufflers, and the parts needed, see the 4.0/4.6 muffler replacement page)

Center Muffler:
The genuine center muffler and associated tubing is available from The Rover Connection for $185. One is now available from British Pacific (ESR3195, MY 95-97) for $179 and from Atlantic British for the same price. Atlantic British carries the largest selection of 4.0/4.6 exhaust replacement options I have seen, including stainless steel replacements with lifetime warranties.

Rear Muffler(s)
1995-96: Up through 1996 there was only one rear muffler -- the genuine part ESR3538 is $260 from The Rover Connection. The lowest price I have seen so far is for a replacement from Atlantic British for $239.
1997-2002: For these model years there were two rear mufflers. The genuine complete tailpipe/muffler assembly ESR4126 retails for about $400, but can be ordered from The Rover Connection for $280. The lowest price I have seen for rear muffler replacements for these model years is at SpeedyCarParts.com who have the mufflers available as separate parts for only $96.20 each.


Filters Range Rover 4.0 / 4.6 /P38A

Air Filter:
The air filter setup for the 4.0/4.6 is different from the Classic; the genuine part number is ESR341, and the FRAM number is CA8009, Wix number 42272. Alex Schubow reports the genuine filter from the dealer cost him less than the aftermarket ones for the 4.0 engine! (I have found prices from aftermarket suppliers are generally about $12-15). The 1999 and later models with the Bosch intake system have a different-looking air cleaner housing, but it takes the same filter element. For those who wish to try the K&N re-usable filter system, the K&N part for all Range Rover models is the HP2004.

Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics) and the Wix number is 33481. Atlantic British sells a generic filter for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30. I found the FRAM one at partsamerica.com for only $11.99!


Oil Filter:
The Rover V8 is known for losing the prime on the oil pump so it is important to get a filter with an anti- drainback valve. The oil filter used on the 4.0/4.6 is the same as on earlier Range Rovers; FRAM lists the PH16 as a suitable substitute. I found this one at partsamerica.com for $4.49 (October 2004). Alex Schubow reports that Genuine Land Rover oil filters are made by Wix. Paul Supp looked it up on the Wix site and the part number is 51068. A few years ago, Alex bought various substitute oil filters at auto parts stores, finding that prices for Bosch were around $3-4, AC were around $3, Mobil-1 were around $5-6. Bruce Powell uses a PH8A instead due to a larger size in height thus holding a bit more oil which he feels might be better for cooling too. A great deal of information on different oil filters can be found at this link.

Pollen Filters:
For quite a while, genuine pollen filters (BTR8037) were less expensive than aftermarket replacements. Now they are both about $14 each from most mail order houses (2 required).


Transmission Filter Kits: Every 30,000 miles the transmission filter is supposed to be changed. (For details on this operation see the 4.0/4.6 transmission service page). The kit to do this, complete with new gasket and O-rings, can be obtained from aftermarket sources such as Atlantic British sells it for $59.95 and SpeedyCarParts.com (click on "Rover" parts) for $36.09. The lowest cost I have seen so far (October 2004) was at partsamerica.com where they list a generic substitute kit for $17.47!


Fuel Delivery System Range Rover 4.0 / 4.6 /P38A

Fuel Filler Cap:
Land Rover Part Number NTC5418: This is one part that is cheaper than the Classic equivalent! I was surprised to find it at Atlantic British for only $11.95. If you are willing to try generic parts (at your own risk -- I don't know if they have the correct air and cacuum venting -- let me know how they do!!) Stant lists the 11819, available from Kragen, Schucks, Checkers etc through partsamerica.com for $7.38. ExpressAutoparts.com lists it for $8.44, and an even lower cost Gates equivalent (#31612) for $6.34!! To find these, click on their "Cap (gas/rad/oil)" parts category.

Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics). Atlantic British sells a gneric one for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30.

Fuel Pump:
Model years 1995 thru 1997 use part number STC4344. The genuine Land Rover part now costs about $360. The best price I have found for a full "plug & play" replacement (April 2004) is $299 at British Pacific and from Atlantic British for $289, including the necessary ring seal for the top of the pump (a $12 item). You can also get the complete assembly minus the seal from SpeedyCarParts.com (click on "Rover" parts) for about $300 with free shipping, which may work better depending on shipping costs. Evan Amaya reports finding a generic equivalent -- the Airtex E3270 -- which worked perfectly for him and only cost him $100 at a local auto parts store. Like the generic replacements for the Classic, this is the pump and motor only, and has to be installed in the original mounting assembly. (See photos on 4.0/4.6 fuel pump replacement page). This pump was used on a number of GM cars. I found this pump at partsamerica.com for $96.99, and the same thing in the "Master" brand for only $74.99 (search for "E3270" on the partsamerica site).


1998 and later models use part number STC4345 which is more expensive -- the best price I have seen for the genuine part is $380 from The Rover Connection. However I was surprised to find it recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $295 with free shipping.

Fuel Pump Relay:
I found this for only $7.95 at Atlantic British

Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.


Fuel Tank Cap:
The genuine gas tank cap is available at The Rover Connection for $27; I found a replacement for this at SpeedyCarParts.com for $18.


Inertia Switch:
This turns the fuel system off in case of collisions. It is an expensive part, but I found a generic version manufactured by Standard at JCWhitney.com for $56.44 (Click on "Replacement Parts"). ExpressAutoparts.com has a similar unit to fit the Range Rover for $57.79.


EFI Parts:
See Fuel Injection System section below.



Fuel Injection (EFI) System

ECUs:
Car Electronic Services can supply rebuilt engine ECUs for the 4.0/4.6. RPI Engineering offers ECU upgrades, available in the US through East Coast Rovers. Kelly Minnick discovered that a company called Superchips Inc produces performance upgrade chips for vehicles previously considered "unchippable". They developed an enhanced chipset for the Range Rover 4.0SE which requires 2 chips instead of one (due to the 4 coil ignition system) and boosts output by 19 bhp and 30 ft-lb of torque. The Rover Connection also lists a Powerchip brand performance chip for about $490.

EFI Parts:
Richard Keys of ATP Electronic Developments Ltd reports having a huge range of remanufactured electronic fuel injection parts available for all Range Rovers.

Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.


Fuel Pressure Regulator:
Most aftermarket suppliers do not even list this part, however I found a Lucas brand one recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $136 with free shipping.


Idle Air Control Motor:
This item (ERR4352) is not a constant troublemaker on the 4.0/4.6 as it is on the Classic, but on the downside it has certainly been known to fail and is even more expensive than the Classic equivalent. It seems to be the same part for all models including the later Bosch engines. Lee Schierbaum had a problem with this unit on his 1996 4.0 and instead of the $200-plus genuine item he located a NAPA replacement part (Echlin #2-1856) for $52. The part also fits a Jeep. Another part number I have seen for this is AC-151. Matt LeFande (September 2004) found an even less expensive replacement at partsamerica.com -- a Borg Warner 21774 for $39.95! They also have a Niehoff Ignition 21774 that can substitute.
If you would rather use a regular Rover parts supplier so you know for sure the unit will fit and work according to spec, the best price I have seen for this part (October 2004) is $139 at British Pacific (part number ERR4352).


Mass Airflow Sensor:
The OEM part for the 95-98 models is over $600, but I found a generic replacement for this part at SpeedyCarParts.com for $398 with free shipping. In 1999 the part changed for the Bosch engine controls, and I found the MAF sensor for these models at SpeedyCarParts.com for only $290.


Oxygen Sensors:
The US spec 4.0/4.6 has 4 Oxygen Sensors(one ahead of and one behind each catalytic converter), so replacing them all can get expensive. NOTE: If you get an aftermarket replacement, make sure it is a full 4-wire version, not a "4 wire to 3 wire" version -- see below. One useful source for looking up the sensors specified for the 4.0/4.6 is the manufacturer's website, NGK -- at www.ngk.com.

OEM "plug and play" replacements are available at The Rover Connection; the genuine O2 sensors for the 95-97 models (ERR1834) can be ordered from them for about $220 each, but they can supply aftermarket ones for $130. Sensors for the later models (AMR6244) are $180 from the same supplier. The lowest price I have seen for the OEM style plug and play sensor is $115 from automedicsupply.com (earlier model years); the lowest price I have found for the 1998 & up models is at Atlantic British which has OEM plug & play O2 sensors for $77.95 for the front ones (MHK100940) and $69.95 for the rear(MHK100930)!! (select their exhaust" category).


Michael Nix had the "Check Engine" light come on recently on his wife's 96 Range Rover. A trip to the dealer revealed confirmed that the engine had a slow oxygen sensor. Instead of paying the $275 from the dealer, he got one at a Nissan dealer for $90 (part number: 22690-85E10). He spliced the Range Rover connector on to the Nissan sensor and it fit perfectly. Three out of the four wire colors even matched up. I recently found this part by searching for its part number at SpeedyCarParts.com for $58.43!!

Alan Rawson delved more deeply into the O2 sensor problem on his 96 RR, adding substantially to our collective knowledge. He found the dealer price had dropped to $130. He found NAPA offers a similar item but with different connectors, their part # OS 778 (I recently looked it up and priced it at $81.99; it looks like the Nissan part mentioned above). Alan initially chose a Nissan part by NTK, which he found for $56 at a web company in southern CA., www.automedicsupply.com (their part # 250-2505). However, this replacement was a curious one with 4 wires at the connector reducing to 3 at the sensor. The vendor thought it would work fine, since the 4th wire is just data ground. All appeared to be OK at first, but Alan found that when the wires to one sensor were sheared off during an off-road trip the GEMS computer could not detect the problem (no light came on) and gas mileage went down the tubes. After further research, Alan found another part by NTK for $89.99 (current price $114.95 as of October 2003) which has the OEM connector (www.automedicsupply.com part number 250-8004) listed for the 4.0, quoted to replace OEM #70399A-- that number was stamped on his old original ones!). The 4th wire provides data ground, and with the semiconductor circuits used in the GEMS computer it appears to be important to have this separate ground, so the computer can detect failure of an individual sensor through the ground circuit. Ron Beckett checked the NGK manufacturer's website at www.ngksparkplugs.com and reports that their part number for the O2 sensor with the right plug for 95-98 models is 25017. Their UK site calls it a OTD3J-5C1, number of wires 4, connector style 57, lead length 521 mm. On Australian models a 3 wire unit is specified, OTD3G-3A1, with connector style 55.


Lowest Price (95-97 models): After scouring different sources for these parts, the best deal I have found so far was from a part number search for the Nissan equivalent 22690-85E10 at SpeedyCarParts.com (their part# C5010-65234) and found it there for $58.43 (free shipping). (To do a part number search on their site, go to the "Replacement Catalog" link on their main page). This is a Bosch part# 13388, and is the 4 wire version but with two connectors -- the wires can easily be spliced to the single Range Rover connector from your old part. For "Direct Fit" replacements with the OEM connector, the lowest price I have found is $114.95 at automedicsupply.com.(Click on year and make "Land Rover").
1998 & up models: the lowest price seems to be at Atlantic British which has OEM plug & play O2 sensors for $77.95 for the front ones (MHK100940) and $69.95 for the rear(MHK100930)!! (select their exhaust" category).


Ignition System Range Rover 4.0 / 4.6 /P38A

Coil Pack and Individual Coils:
The 4.0/4.6 uses a four-coil pack costing about $700-800. Usually only one of the four coils fails, but parts houses only sell the complete pack. Walter Gates recently reported spending $750 on new ones after his failed and caused misfiring and rough running. (For details of diagnosis and replacement see the 4.0/4.6 Ignition Coil Failure, Diagnosis &Replacement Page).I recently found the complete pack for $619.95 at Atlantic British. SpeedyCarParts.com (click on "Rover" parts) who recently had them (April 2004) for $621 with free shipping. Patrick Bennett has subsequently discovered that Car Cannibal can supply individual coils (used but warrantied) for about $60 each. Email me if you find a less expensive source!


Crankshaft Position Sensor:
This sensor's failure is often the cause of intermittent ignition problems. The genuine part is about $64; SpeedyCarParts.com (click on "Rover" parts) has it for $44.83. (search under "engine electrical - reference sensor") and I recently found an aftermarket one at Atlantic British for $37.95.

Ignition Leads:
A full set of aftermarket ignition leads cost around $50-60 from any of the sources I have checked. Email me if you find one for less! Update September 2004: I just found out that British Pacific offers a set of leads for the 4.0/4.6 models for only $39.99! This is part number GWS101 for the GEMS models (95 to 98) and GWS102 for the Bosch models (1999-2002). Use their part number price lookup feature to get current pricing and specials.
I recently found an aftermarket lead set from Nology that claims to boost horsepower. It is probably only a mild boost and there may well be other ways of increasing power for less money, but if you are interested see this link: Land Rover Range Rover V8 95-97 Nology HotWires

Spark Plugs:
The original equipment plug is the Champion RN11YC. Generic parts are Autolite 64 (available for about $1.45 each from Kragen or AutoPartsGIANT.com). SpeedyCarParts.com (click on "Rover" parts) lists many replacement alternatives from a $1.45 Bosch plug to a $13.61 Denso Iridium IW16 plug.



Radio


Range Rover sound systems are supposedly designed to withstand the rigors of off-road use but I personally have found they need replacing or repairing at regular intervals. For example, the LCD panel on the radio goes dim on one side if one of the bulbs illuminating it from behind fails. The procedure for replacing the backlight bulbs is detailed on the Radio Display Backlight Bulb Replacement page, but is a slightly tricky operation (sometimes resulting in further damage from the soldering iron such as burnt LCD microchips and connections). This and other radio problems can of course be fixed by paying the $1500 requested by the dealer for a new radio, but I recently discovered that John Monaghan of Roverville Radio Repair & Exchange provides top quality radio work with all genuine factory parts at a fraction of Land Rover's prices and down time. John specializes in the Clarion Diversity units (AMR 2672) used on all 4.0/4.6 models from 1994 through 1999.5, and the RTC7788 model used on Defenders. He also buys these units in any condition and sells fully reconditioned units for $425 (a far cry from the $1500 Land Rover price). He actually repairs these units for many Land Rover dealers who do not want to wait several months for the official Clarion repairs -- John's usual turnaround time is a splendid 24 hours from the time of receipt. John has kindly agreed to help sponsor this website, so if you use his services please mention you were referred by Rangerovers.net.


Scan Tools Range Rover 4.0 / 4.6 /P38A

TestBook:
This is the official Land Rover diagnostic system used by the nealer network. It is basically a custom touchscreen controlled portable computer that connects to the 16 pin OBD-II plug under the dash, but accesses many more vehicle functions than standard OBD-II systems. It basically accesses anything that is computer controlled, which is nearly everything -- the engine, transmission, transfer case, suspension, BeCM, ABS, cruise control, and on and on. Originally, the system was not even available to anyone outside the dealer network, making it doubly frustrating when you run into the notation "Refer to Testbook" in the factory repair manual. Even though "Testbook" is now available to the public as an official Land Rover part, most private owners and local repair shops cannot afford the $20,000 tariff for it, so aftermarket equivalents have been developed by other manufacturers to fill the void (see below).

Rovacom Diagnostic System:
The Rovacom system was the first aftermarket equivalent for the "TestBook" to become available. It is claimed to be even better than the TestBook. It is certainly more portable. It uses a rugged custom case and hardware with a 12 inch touch screen. It draws its power from the vehcile's diagnostic connector or a 12 volt jack. The unit comes with all the software installed for the various Land Rover models, but you can pay for only the ones you want activated. The basic unit with no software activated is about £2,000. Thus, you can get a system customized to cover all the systems on your particular Range Rover 4.0/4.6 for about £3700 ($6,000). Rovacom recently started selling used units for up to 50% off, bringing them down to the £4,500 range ($7300) for units with software activated for all models. In the US the Rovacom system is available through Rovers North ([email protected] and ask for Arthur or George) or British parts International (Phil Prince, [email protected]).
Update: In 2003 the "Rovercom Lite" system became available, allowing customers to purchase only the functionality they need for their own model, and run the software on their own laptop computer. This has brought the price down to the region of £600 ($1,000), which is getting within the reach of owners who may live a long way from the nearest dealer.

Autologic Diagnosis System:
The Autologic Diagnosis System is another aftermarket TestBook equivalent. In the US it is available through Atlantic British. Their price is $10,500 for a complete system covering all late model Land Rovers -- feasible for some local shops but not many individual owners.

OBD-II Scan Tools:
Standard OBD-II scan tools can give you much of the same information as TestBook about engine and transmission fault codes, although they will not let you diagnose some of the other systems like the electronic air suspension. Trevor Briggs and Kelley Minnick found an OBDII Automotive Scan Tool Browser for $122 from Alex C. Peper, 67 Scotch Pine Dr., Islandia, NY 11772. This generic OBD II software gives the basic readouts and can reset the various codes. (Choose ISO gateway router for Range Rovers, rather than the VPW or PWM versions for GM and Ford vehicles). It runs on any Windows 3.1, 95 or 98 computer, 386 or higher, and is optimized for low cost laptops. The system includes a protected RS-232 interface, OBD-2 connector and cable, world wide shipping, handling and taxes. You can actually download the "software only" for free, and make your own cable and interfacing. New browser features advertized include Land Rover, Nissan, Subaru defined test results.

Michael Nix went to Auto Zone and bought an Actron OBDII diagnostic tester to diagnose the oxygen sensors on his wife's 96 RR. (Actron's web-site is www.actron.com. Their latest hand-held Actron scanner is really convenient and works on all American and Imported OBD-II vehicles. It is sold thorugh JCWhitney.com for $159.99. On the older version Michael used (CP9035F), he found the codes had to read and reset with the engine running, which is contrary to what the manual said. Also, it took multiple tries to read the codes and reset the check-engine light.

Danny Ledford reports that TRW has a scan tool called the Laser 2000 that is very affordable. He says it does engine management, ABS, and electronic air, and works on new OBD-II and older serial ports.

The Lowest Prices I have seen for a full function hand-held OBD-II scanner for the 4.0/4.6 are $106.95 for the Actron CP9135 at Tradervar, and $114.99 for the Equus 3100 at partsamerica.com. This scanner works on all US and foreign vehicles. I saw the older, more basic Actron CP9035 (mentioned above) with only a digital numeric readout on sale at Tradervar for $59.95.


Sound System

See Radio section above.

Steering Range Rover 4.0 / 4.6 /P38A
Steering Damper:
OEM steering dampers are available from Atlantic British for $97.95 plus shipping (April 2004). The SpeedyCarParts.com (click on "Rover" parts) sells them for $82 with free shipping.

Power Steering Box:
This is not a weak point as it is on the Classic; however when it does fail it is even more expensive than on the older model. The lowest cost I have recently found (April 2004) for the brand new genuine part is $1195 from Atlantic British.-- this includes the core charge which is refundable.
The lowest price I have seen for a rebuilt 4.0/4.6 steering box is a remanufactured unit by Maval sold by SpeedyCarParts.com (click on "Rover" parts) for $353 with free shipping. However last time I checked this was no longer available -- please email me if you find a better one.


Power Steering Pump:
Until recently, the lowest costs I had seen on these were for rebuilt units from ExpressAutoparts.com for $216 and AutoPartsGIANT.com for $182.75 (both with free shipping). However more recently (April 2004) I found the steering pump at Atlantic British for only $119.95!!



Suspension Range Rover 4.0 / 4.6 /P38A
Air Springs (Complete)
Air Springs (Bladder Only)
Air Compressor
Coil Conversion Kits
Delay/Turnoff Timer
ECU
Shocks

Air Springs (Complete):
These used to be very expensive but have been coming down in price. The Rover Connection has the front spring for $150. SpeedyCarParts.com list it for $148.77 with free shipping. The same part is now available (April 2004) at Atlantic British for as little as $119.95.
The rear springs have a longer rubber bellows and are still somewhat expensive; they are $189.95 from Atlantic British and $280 from The Rover Connection. .


Long-standing aftermarket air suspension maker Arnott Industries has been active in developing replacement air springs for Range Rovers (the owner drives one!!). They have several options. Complete replacement air spring assemblies similar to OEM are $105 (front) and $169 (rear)! They also make an improved second-generation design (far superior to OEM), with crimped bellows attachments. These are sold in pairs -- $205 a pair (front) and $358 a pair (rear). Tey also make bellows-only replacements (see below). It is hard to believe for long-suffering Range Rover owners used to air suspension problems, but all Arnott part come with a Lifetime Warranty!! Typical of Arnott's quality approach is their detailed installation instructions, with photographs, on their website. Daniel Golenia of Australia reports: "I imported a set and they transformed the ride quality of the vehicle."
Car Cannibal offer new air springs complete with limited warranties for similar pricing.


Air Springs (Bladder Only):
An aftermarket US manufacturer and supplier, Arnott Industries (who make air spring components for other vehicles such as Ford cars) now sell a replacement rubber bladder only (you re-use the aluminum or plastic top and bottom of the spring) for $89 each for the front and $105 for the rear. These parts have a lifetime warranty. Typical of Arnott's quality approach is their detailed installation instructions, with photographs, on their website.
Recently, a US manufacturer of coil conversion kits, Strutmasters, started offering replacement spring bellows and has the lowest cost I have seen (February 2005) for them in the US. They sell the front bellows only for $79 and the rear one for $95. Their parts also come with a lifetime warranty. This is hard to believe for long-suffering Range Rover owewners, but this effectively put an end to expenses on new air springs!!


Another new option (May 2004) is an Australian company called Airbag Man who supply RR air bellows worldwide for front (their part # AB0001) and rear (their part # AB0002) of all Range Rover models. Their own specially made versions are produced by Dunlop (same factory as original units). This provides the assurance of performance at least as good as original (they state the Arnott's units, by comparison, appear to be quite short once aged). Their export price is A$110 - about US$80 for either front or rear bladders. (Prices for Australian customers are significantly higher due to local import duty and taxes). Airbag Man's rear bellows are longer than the factory units as the originals start to leak and fall off once aged; this also allows a small suspension lift as has been carried out by Hardy Neale of Australia recently.

Compressor:
The Range Rover air suspension compressor sells for $440 at the dealer (November 2003). It does wear out and at 130,000 miles mine needed replacing. Until recently it (like other air suspension components) has not even been listed by aftermarket suppliers. However searching around for a replacement for mine, I found it recently in the new Atlantic British catalog for $389.95, The Rover Connection for $385 plus shipping, and at SpeedyCarParts.com for $370 with free shipping (listed as "suspension pump").


I recently discovered that Airbag Man in Brisbane Australia sells brand new compressors to export customers for A$400 or US$300 for inexpensive worldwide shipping, They also supply a compressor service kit from the OEM manufacturer (Thomas Pumps) that includes new sleeve and piston/conrod assy, and sells for A$200.00 or US$150. (prices to Australian customers are higher due to local import duty and taxes).

When my compressor went out at about 140,000 miles I obtained a used one from a wrecker for $225. Subsequent traffic from Ron Beckett and others on the rro email list suggested the Range Rover compressor might be a generic Thomas pump, and after searching their catalogs I concluded it is their model number 315CDC5612 (specs available on the Thomas Pumps site at this link). This is a 1/5 horsepower model with a thermal cutout and is rated for intermittent duty up to 150psi (the pressure used in the EAS system). Independently, Abe Thietten found a Thomas 315 series compressor at Puma Sales for $109, but I am not sure if this is the exact replacement as there are at least 7 identical-looking models in the 315 range with different specs (only the 315CDC5612 can attain the necessary 150 PSI, and the "standard" 315 model only reaches 130).



However, Abe reports that he found a better alternative at the same company, the more powerful 1/4 horsepower Blowjax DC2000 for $99 that he says fits perfectly. (See the EAS compressor diagnosis, replacement and repair page) You can line up the bracket on old air compressor with the new one and drill two holes to attach, easy. Because of this compressor's slightly larger size, the lid to the EAS system will only attach on the front not on the back, but that is no big deal. For the air line, the old adapter screws directly into the new Blojax air compressor, but before you do this you will have to rotate the top cylinder head so it points backwards. This pump comes with a filter and it is located on the side; it fits into the enclosure with no modification. The Blowjax pump is rated for a 50% duty cycle as opposed to the 15% of the OEM part, but does not have thermal cutout protection. Therefore you need to ground the thermal sensor wire going to the compressor connector to fool the Range Rover suspension ECU into thinking the non-existent thermal switch is working. As a result, there is a possibility this pump could overheat, so use at your own risk (Abe reports it runs very cool however). When using all these generic replacements you will also need to re-wire them using your old connector.


For more information on compressor replacement with genuine and generic replacements, see the EAS compressor diagnosis, replacement and repair page.


Coil Conversion Kits:
For those who are tired of dealing with the EAS, several manufacturers and vendors now offer coil conversion kits for the 4.0/4.6 models. Atlantic British offers a kit with aluminum perch adapters, instructions, a specially developed EAS override module to eliminate error mesages, and coil springsdesigned to ride at standard height, for $849. They also sell a heavy duty off road version with a higher ride height for $949. I recently discovered (Sept 2004) that British Pacific has developed a heavy duty conversion set, which has upgraded Old Man Emu springs, hardware and instructions, and their EAS override 'black box' to tell the BECM computer that everything is fine. Extensively road tested. Vehicle height just a touch higher than the middle setting on the air suspension. Uses existing shocks. $799.95.
A new development in this field is the Arnott Industries coil conversion kit, also using existing shocks, for $579. Typical of their thorough approach, their spring seats are CNC machined from solid 6061-T6 aluminum alloy, and the mounts are designed to bolt directly to the current suspension brackets. The kit features powder coated variable rate coil springs made in the USA, and includes step by step instructions on how disarm your EAS alarm. Strutmasters makes a simpler kit with fewer components for $495.


More information on this topic can be found on the 4.0/4.6 Coil Conversion Page.


Delay/Turnoff Timer:
(ANR4652): This part supplies power to the EAS ECU, and controls the periodic activation of the system even when the ehicle is unattended. On inspecting mine I found it is made by TRW, whose part number for it is 51606A0A. It therefore ought to be available from some other source -- please email me if you find one!


EAS ECU:
My parts manual states ANR3773 was used up to mid 1995 (VIN #MA308966). After that, it was ANR4499. David Sparks reports (November 2004) that the earlier versions are no longer priced, presumably meaning they have been replaced by the third version (RQT10040). If you buy this part new, it is the third version you would be quoted for.
Rovers North lists the regular price of the ECU as $392.13, but has them on sale for $159. (They use part number RQT10040). Another good source for ECUs is Car Cannibal, who specialize in recycled Rover parts and warranty everything they sell.

If you tire of the OEM system, Dakota Digital makes a complete air suspension control system for $795 including a remote control option. It does all the automatic ride height functions, as well as lets you control each bag individually. It also comes with a nice display to let you know what's going on. If anyone tries this, please email me so we can share your experiences with other owners.

Shocks:
The lowest price I have seen for the genuine shocks is at The Rover Connection for $90 each.
Various aftermarket shocks are available for the 4.0/4.6. Probably the most popular upgrades are the famous Bilsteins; these are now advertized at SpeedyCarParts.com (click on "Rover" parts) for $96 with free shipping. Kevin Kelly found them at www.shox.com which sells them for $314.80 for a set of four. Atlantic British offers aftermarket Boge replacement shocks for $89 each or $279 for a set of four. SpeedyCarParts.com also has an aftermarket shock by KYB specified for the 4.0/4.6 for $70. (free shipping). AutoPartsGIANT.com offers some KYBs for about $64 front and $61 rear (search for a late model 4.0/4.6 such as 1998). Brent Wilhelmi found Monroe Wilderness 4x4 shocks (RS010 front, RS001 rear) for his 4.6HSE for $62.95 each at DAP Enterprises.
The lowest price I have seen for 4.0/4.6 shocks is at British Pacific who offer their version of the "original type" shock for only $52.50 under part # STC3672 (front) or STC3671 (rear).


Transfer Case

I have yet to see new 4.0/4.6 transfer cases offered by aftermarket parts houses. One temporarily offered a rebuilt unit for $2,300 but they are no longer available. Recently (Feb 2004) I was surprised to come across rebuilt and fully warrantied (12 months and unlimited mileage) units at Car Cannibal for only $1,850. They even have rebuilt examples of the Callaway T-case (which was uprated for more torque and power) for $2,150.

Transmission Range Rover 4.0 / 4.6 /P38A

Rebuilt and Used Transmissions
Rebuilt ZF electric shift automatic transmissions for the 4.0 used to e extremely expensive, when available at all. However, I was recently amazed to find rebuilt units available from Car Cannibal for only $2,195 with a 1-year unlimited mileage warranty. The 4HP24 variant used on the 4.6 is $2,250.
Because the ZF transmissions used in Range Rovers are also OEM equipment in many other vehicles, some transmission rebuilding and parts houses also have them. Dwight Smith found a very low cost generic source of the electric shift ZF 4HP24 used in the 4.0 and 4.6 -- Phoenix Remanufactured Transmissions who have it for $1,250!! (You should check with them by phone for the minor variations for your exact application). Phoenix is a major rebuilding and parts house, and all their remanufactured transmissions are dyno tested and warrantied.


Used (not rebuilt) transmissions are another option -- I found they can be obtained from Car Cannibal for $850 for the 4.0 unit and $1,000 for the 4.6. Even these ones include a 6 month, 8,000 mile warranty!


Transmission Filter Kits:
Every 30,000 miles the transmission filter is supposed to be changed. Since the ZF transmission, with variations, is used on a number of other European vehicles, the filter kit to do this can be obtained from aftermarket sources. Atlantic British sells it for $59.95 and SpeedyCarParts.com (click on "Rover" parts) lists it for $35.


Washer/Wiper System Range Rover 4.0 / 4.6 /P38A

Headlight Wiper Blades:
Robert J N Watson reports that the little short wiper blades for the headlights (DKC100860) seem to be $13 each at the dealer or $26 for a set of two. He found that one 'narrow fit' blade for $3 can be sectioned to length to replace both! Ron Beckett bought a wiper blade at Kmart and cut the notches to fit the headlight wiper arms.
Washer System Pump:
The front windshield washer pump costs $57 from Rovers North. However, I found it for $15.33 at ExpressAutoparts.com!! (Select brand "Land Rover", and look in the "wiper" category. Part number is 65-01). I also found it for $14.99 at partsamerica.com. The lowest price I have seen for the same part was at JCWhitney.com for $12.95 (although it takes a lot more searching work to find it on their site!)

Windshield Wiper Blades:
Genuine wiper blades are expensive; even The Rover Connection charges $15 each for them, and the cheapest aftermarket ones offered by Atlantic British cost $12.95 each. I found Bosch replacements at SpeedyCarParts.com (click on "Rover" parts) for $8.42 each (in their body electrical category), but ExpressAutoparts.com have AC-Delco replacements for $4.01 each!!!


Wiper Blade, Rear:
This is a different part on the 4.0/4.6 -- Atlantic British sells an aftermarket one for $12.95, but I found Bosch replacements for $5.45 at Speedycarparts.com! (in their body electrical category).

Wheel Bearings Range Rover 4.0 / 4.6 /P38A

Genuine and Aftermarket Parts: The Range Rover 4.0/4.6/P38 had new lighter, stronger and simpler axle assemblies. The wheel bearings are pressed into the hub, eliminating the need for the inumerable seals, gaskets, washers, spacers and other paraphenalia that makes the reassembly of a Classic hub impossible without referring to a diagram. The only downside is that the procedure for replacement of the wheel bearings, according to the shop manual and Land Rover dealers, is to replace the entire $500 hub assembly as a unit. The lowest prices I have seen for these assemblies are at Rovers North, which has the rear hub assembly (FTC3223) for $466, the front left (FTC3243) for $469 and the front right (FTC3226) for $499. However Atlantic British now has a much less expensive solution -- they can sell you just the bearings already (part number FTC1507) for $199. In this case you need a means of pressing the old bearings out of the hub and the new ones in.
Generic Parts: When replacing my right rear hub assembly (see hub and bearing replacement page), I found the inner bearing was a Timken unit inscribed with part number NP275832. It also had a "DV" symbol on it, and was made in France. (I think front and rear use the same bearings). Andy Cunningham (at this link) describes the numbers printed on the boxes of Joe Godfrey's Timken bearings he got from Kaid Ltd in the UK for about GBP80 ($150). These were NP275832 followed by "90VA1" or "90UA1" (unclear). Also on the boxes were the numbers 200304 FR and 64922. DAP Industries sells an equivalent as partnumber FTC-3223B for $110. Recently, (January 2005), I found replacement bearings at Speedycarparts.com, who specify SKF bearings for front or rear (2 per wheel needed) for $28.76 each or $57.52 per wheel.
If you have tried using generic parts for this job, please email me!!).

Please email me if you have any other information on replacement parts for the 4.0/4.6.

Thanks for the plug coach!

The EAS on the p38 is a much refined version of the classics, and if taken care of will work very well with no troubles. I overhauled my entire system, including new airlines, airsping bladders, compressor internals, and valve block orings for a total of about $500, over $400 of that was the bladders.

The "valve stuck" fault is often the ECU's way of diagnosing a compressor problem. If there is no air in the tank, opening the LR valve will not raise the LR corner. The ECU isn't smart enough to realize that there's not enough air pressure to lift that corner, and assumes the valve won't open.

It's been 10 months since the initial post, what's happend to this Rangie?
Did it get castrated?

BECM

Car Electronic Services rebuilds BECMs on an exchange basis. New ones can be obtained through The Rover Connection for about $790.

Body & Chassis Parts Range Rover 4.0 / 4.6 /P38A

Tailgate & Hood Struts
Tailgate Strut: Aftermarket replacements for the tailgate strut are available at SpeedyCarParts.com (click on "Rover" parts) for $27. I recently (October 2004) found it was even less at British Pacific (their part number ALR10050) for $24.25. I recently found (October 2004) that Atlantic British trumps all comers in this category with a price of $29.95 for the pair!!


Hood strut: The genuine part allows locking of the hood in the position and costs a lot -- well over $50. SpeedyCarParts.com have a low cost non-locking replacement for the hood strut for $26.24.


Grille:
I discovered that the genuine radiator grille is now available from Atlantic British for $189.


Rear View Mirror:
Paul Smail of Annapolis MD reports "I have twice replaced the auto-dimming mirror in my Range Rover. A couple of years ago I purchased a comparable replacement directly from Donnelly (OE manufacturer) after being quoted nearly $700 for a genuine replacement. The ersatz replacement cost around $250 and was supposedly better constructed, using some sort of gel photochromic matrix rather than the liquid in the original mirror, plus it had a nifty compass! Notwithstanding this new technology, the replacement mirror waited just until it was out of warrantly to fail. Have since purchased a genuine parts replacement from The Rover Connection out in Utah for a price comparable to that of a Magna-Donnelly replacement. The Rover Connection also have mirrors for other model Land Rovers in the $250 price range.

Wing/Fender:
The easily-damaged front fender or wing is now available from aftermarket suppliers such as Atlantic British, who have it in stock for $459.95.


Braking System Range Rover 4.0 / 4.6 /P38A

ABS Accumulator:
Most suppliers do not seem to list this part separately, but I did find it at Rovers North for $326. SpeedyCarParts.com (click on "Rover" parts) lists new units for $239 with free shipping. Recently, (October 2004) I found it at British Pacific (STC2784) for only $199.99!


ABS Pump:
This component is so expensive that most suppliers don't seem to even list it. I did find it at Rovers North for $1075, but the lowest price I have found so far is at British Pacific, who have it for $999.

Calipers & Caliper Repair Kits:
When the calipers start leaking, the new ones (especially for the front) cost over $300 each, or you can get rebuilt ones (eg Rovers North has them for about $141 each for the front ones, and partsamerica.com has them for about $135). Alternatively, you can easily rebuild them yourself, using an aftermarket caliper rebuild kit that includes all the seals -- I found one for the 4.0/4.6 at SpeedyCarParts.com (click on "Rover" parts) for only $41 for the front brakes and $29.97 for the rear. I also found one for the front brakes at British Pacific (STC1919) for $15.99, who also have rear kits (STC1909) for $26.95. Atlantic British does not have the front kits but has one for the rear for only $14!

Caliper Guide Pin Kits
A more common problem than worn out or leaking calipers is frozen caliper guide pins, which you will notice when you try to do a brake job. I shopped around and found Atlantic British has them for $28.95 (front axle set) and $26.95 (rear axle set) including new pins, rubber boots and special lubricant.

Pads:
Part Numbers: Front STC3685, Rear STC3684. Dealer Price (Oct 2004) approx $180 per axle set.
Atlantic British offers several aftermarket brake pad options from $44.95 to $130 for front pad sets and $32.95 to $100 for rear sets. British Pacific stocks the genuine front pads (SPF100460G) for $69.95 and the well-known Ferodo aftermarket brand for $44.95 (SPF100460). For the rear pads, they stock two options -- SPF100470F for $59.95 SPF100460P for $39.95.
The lowest prices from Rover aftermarket specialists for the front pads seem to be British Pacific (SPF100460) Ferodo brand pads and Atlantic British Lockheed brand pads (made in the UK) for $44.95.
For the rear pads, I thought the record was held by SpeedyCarParts.com (click on "Rover" parts) for Deluxe PBR brand pads for $35.78. (Their options for the front include $70 for Mintex and $96 for OEM Lucas pad sets). However, Atlantic British now (October 2004) offers the highly respected Lockheed brand rear pads for only $32.95!!
If you want to try a real generic part (not really advisable when it comes to brakes in my opinion!), you can try the Wagner rear pads I found at AutoPartsGIANT.com for $26.00 or the rebuilt "Wearever Silver" ones from partsamerica.com for $11.48 -- if you attempt this please let me know the results!!
Parking Brake Shoes:
I have not seen these listed in mail order catalogs but SpeedyCarParts.com (click on "Rover" parts) has them for $121 for a set with free shipping.


Rotors/Discs: The extra weight and speed of the 4.0/4.6 models is hard on brakes an they seem to wear out the rotors rapidly. The stock front brake rotors are $81 from Rovers North, but aftermarket units are now available. The lowest prices I have seen after searching many sources are the following:
Front: SpeedyCarParts.com (click on "Rover" parts) Brembo front vented discs for $65 each (their rear ones are $46). Atlantic British has aftermarket front rotors for $50.95.
Rear: Atlantic British has rear rotors for $41.95 each.

Climate Control Range Rover 4.0 / 4.6 /P38A

A/C Compressor & Clutch:
The compressor/clutch assembly is now about $500 from discount mail order houses such as Atlantic British, which is a bit lower than prices for the Classic equivalent. In October 2003, Alan Rawson reported finding a company in Abilene, TX that rebuilds compressor clutches and has a stock of other parts. Hancock Industries (http://www.hancockindustries.com/) sold Alan a rebuilt AC clutch for $110 (+$50 core). It turned out to be very easy to take the old one off his '96 4.6HSE and slip the new one on w/o disturbing the AC charge--it only took courage dealing with the unknown. They sell a complete (rebuilt?) compressor w/clutch for $250 ($75 core). The parts had no written instructions since they are intended for professional AC shops, but John, in the Hancock rebuild shop, was extremely helpful in explaining how the clutch was mounted and what to do in getting it off, how to set the air gap. I did find a generic replacement for the clutch bearing at partsamerica.com for $42.99 (retail cost given as $129).
Please email me if you find any other low cost generic replacement for the A/C compressor or parts thereof.


A/C Condenser Unit:
This is a very expensive item to replace. I found aftermarket versions of the condenser only at Atlantic British for $429.95, or the complete unit with fans for $949.95. SpeedyCarParts.com has the complete assembly (Valeo brand) with fans for only $772.94.


A/C Receiver/Drier:
I found this item for $119.95 from Atlantic British. I also found it (October 2004) in stock at SpeedyCarParts.com (click on "Rover" parts) for $83.97 with free shipping! If you wish to try a generic solution, the Ready Aire 4086 is listed for the 4.0/4.6 by partsamerica.com for only $61.99!


Climate Control Head Unit:
The control panel and ECU that is the mastermind of the 4.0/4.6 climate control system usually costs about $600 even at aftermarket parts suppliers I have searched. I was therefore pleasantly surprised to find it at Car Cannibal for only $395 exchange, for models with or without heated seats, whether the problem with yours is display readout failure or complete malfunction.

Expansion Valve:
Until recently I was never able to locate a low cost source for this part; it was not even listed in the catalogs I tried. The usual replacement part is about $180, but recently (October 2003) I finally found a generic replacement (Egelhof brand) for only $34.79 at SpeedyCarParts.com.


Blend/Flap Motors:
These motors that control air distribution from the heater body are a common failure item (see heater blend motor diagnosis and replacement page). Atlantic British stocks the set of three with the harness (STC3259) for $199. The lowest cost I have seen for them to date (October 2004) is at SpeedyCarParts.com where they have them for $175 (free shipping). The separate blend motor for the fresh air/recirc flaps (mounted to the blower motors behind the extreme left and right fasia vents) can be had for $109 at Atlantic British (STC3266). You should also be able to use this part to replace any single one of the other blend motors insteatd of all three, and splice the leads into the wiring harness.


Heater Core:
This component (STC3261) does not fail as readily as on the Classic, but eventually it does. Unfortunately it is a more expensive part than the old Classsic version. SpeedyCarParts.com has it for $369, and I found the genuine part available at Atlantic British for $339.95.


3-Way Pressure Switch:
This vital component (which attaches to the receiver/drier and makes sure the system pressure is within prescribed limits before it allows the compressor to be turned on) failed on mine (see A/C problems section) and the A/C blew hot air. I found you can now get a replacement at SpeedyCarParts.com for only $82.

Cooling System Range Rover 4.0 / 4.6 /P38A

Belt (Serpentine):
The lowest price I have seen for the serpentine belt (1995-98) after searching many catalogs and websites is $19.99 at British Pacific (ERR4460).
For 1999-02 models, the lowest price I have seen (October 2004) is $22.99 at British Pacific

Belt Tensioner Assembly:
This is a known weak point on the 4.0/4.6. The price of a replacement from Rovers North is now down to $81.52; this seems to be the lowest price currently available (October 2004) if shipping costs are not counted. SpeedyCarParts.com lists an replacement for $87 with free shipping, which would probably work out cheaper overall.

Expansion Tank Cap:
Atlantic British has these (ESR1480) for only $21.95, guaranteed to fit.


Fan Blades
I found these at SpeedyCarParts.com for only $103. Atlantic British lists an aftermarket design, slightly different from the original, for $79.95.


Hoses:
For the radiator top hose (usually the first to go as it is the hottest), aftermarket replacements average about $11. A Gates replacement part #20357 is listed at AutoPartsGIANT.com for $7.82. The lowest price I have ever seen (October 2004) is at Partsamerica.com which has a Drive-Rite brand generic replacement (curved, cut to fit) for $5.99!!


Radiator:
95-98 Models: I found new OEM and aftermarket radiators for 95-98 models (genuine part equivalent PCC106940 for VIN numbers to WA410481) at SpeedyCarParts.com (click on "Rover" parts) for $423 with free shipping. Radiator.com did offer a replacement for $445 but recently they changed their website and I find it too difficult to navigate. The lowest price I have been able to find after searching high and low is at Atlantic British who now list them (February 2005) for $349.95. (To find it, do a search for "radiator" under RR 4.0/4.6 in all categories or the engine category on their website).
99-02 Models: The radiator for the later Bosch engine models is part number PCC106850. SpeedyCarParts.com has them for $394.92 with free shipping, and the lowest cost source I have seen is British Pacific for $389.


Thermostat:
On 4.0/4.6 engines the thermostat is a large, expensive item in a separate housing with several hoses connected to it. After searching many sources (October 2004) I found the best deals at British Pacific which has them for $87.50, and at Atlantic British who have them for $79.95 plus shipping.


Viscous Fan Clutch:
As of October 2004 the cost of the 4.0/4.6 viscous fan clutch is $229 at Rovers North, who also sell an aftermarket versionn for $209. The best deal I can find for this part after searching multiple sources is at Atlantic British for $183.95.


Water Pump:
SpeedyCarParts.com (click on "Rover" parts) have these for $162 (free shipping). Atlantic British now lists an aftermarket water pump for the 4.0/4.6 for $155.
The lowest price I have seen to date is an A1 Cardone brand unit (try at your own risk -- let me know of your experience) for $148 with free shipping at ExpressAutoparts.com.
Update August 2004: The Rover Connection has just announced that they have water pumps for all 4.0/4.6 RR models for $89!!


Water Pump Gasket:
I found a British made generic replacement for this at SpeedyCarParts.com for only $6.52.


Water Temperature Sender:
This sensor that drives the temperature gauge is not as expensive as on early Classics. Aftermarket versions are available at reasonable prices; SpeedyCarParts.com (click on "Rover" parts) sells one for $22 (listed in their "Body Electrical" category, not Cooling System!).


Cruise Control Range Rover 4.0 / 4.6 /P38A

Vacuum Pump:
This item is a fairly expensive one to replace. Even at aftermarket suppliers like Atlantic British it is $404.95. However, I recently (October 2004) found a replacement at SpeedyCarParts.com (click on "Rover" parts) for $150.53 (Body Electrical parts category).


Electrical Range Rover 4.0 / 4.6 /P38A
Alternator:
New Alternators: Dealers charge anything up to $700 for new alternators. Rovers North has aftermarket "ProLine" versions now for $399, and SpeedyCarParts.com has brand new Marelli alternators for the 4.0/4.6 for $365.62. The lowest price I have found for new alternators is at British Pacific which offers new alternators for $314.99 (AMR4247 -- 1995 to mid 97) and $349 (AMR2938 -- mid 97 through 98). These two models seem to be interchangeable. The part for 1999 on is ERR5834, but aftermarket suppliers do not seem to offer it yet.


Rebuilt Alternators: The Rover Connection has these for $220 but with a rather massive $150 core charge! AutoPartsGIANT.com has several options for rebuilt units, with the lowest cost one being only $142! SpeedyCarParts.com (click on "Rover" parts) has rebuilt100 amp Bosch units for $220.86 (October 2004). Partsamerica.com lists an Autolite remanufactured alternator for $211.99.
The lowest price I have found for rebuilt alternators is $142 (free shipping) at AutoPartsGIANT.com, which also has a couple of other brands to choose from.

Battery:
Brian Weaver reports that the replacement battery for the 4.0/4.6 is an Interstate Commercial
battery, the 29H-VHD. It retails for $80.95. Here's a link to it at Interstate's website.


Fuse Box:
Unfortunately this is a failure item on the 4.0/4.6 (see the fusebox problem & repair page for ways you might be able to fix yours to avoid replacement). I recently found (Novemner 2004) that Import Parts Bin/Speedy Car Parts stock new fuse boxes for the 4.0/4.6 (1995-98) for $216.71 with free shipping. (Click on "Rover" parts -- body electrical). They also have the 1999 & up fusebox for $164.17 with free shipping. Atlantic British has replacements for prices nearly as low -- $224.95 for 1995-98 and $169.95 for the later Bosch controlled engines (1999 & up).


Headlight Bulbs:
Sylvania lists their part number 9003 for low beam replacement, (with 9003CB for an upgrade), and 9005 for the high beam. For the auxiliary headlights, they list the H3 55W bulb.
The 9003 (Wagner) is listed for $9.03 at ExpressAutoparts.com. and both the Sylvania 9003 and 9005 (high beam) are $8.49 at partsamerica.com. They also list a General Electric H155 high/low beam bulb for $7.59, among many other alternatives and upgrades.


Fog Lights:
H3 55W

Relays:
Most relays on the 4.0/4.6 are Siemens parts.


Starter Motor:
The costs of aftermarket and rebuilt starters for the 4.0/4.6 have come down recently (October 2003). The Rover Connection has them for $350.
The lowest pricse I have seen for new starters are at Atlantic British who have brand new ones for $199.95 plus shipping, and SpeedyCarParts.com who have new ones for $195.30 with free shipping. British Pacific has them (check with them whether new or rebuilt but I think they are new) for $189.00 plus shipping.
Rebuilt Bosch starters for the 4.0/4.6 by Orange County Alternator are available from AutoPartsGIANT.com for $206. Ampere Automotive brand rebuilt starters are available from ExpressAutoparts.com for $178.83. The lowest price I have seen for rebuilt ones is $145 from The Rover Connection (plus a core charge).



Engine Mechanical Range Rover 4.0 / 4.6 /P38A
Camshaft & Rocker Shaft Components:
SpeedyCarParts.com has camshafts for $233 with free shipping, cam followers for $11, rocker shafts for $78, and rockers for $7.

Engine Long Block:
I recently discovered that Car Cannibal offers complete rebuilt 4.6 engine long blocks including, if you wish, a mildly enhanced cam for more power and torque) for only $4,000.


Head Gaskets:
The 4.0/4.6 is unfortunately notorious for blowing head gaskets. I still recall talking to an owner of a brand new 2000 model who had just had this happen on his.The good news is that replacements, made by Elrin, the OEM supplier to Land Rover, are available for only $10 each at SpeedyCarParts.com! (Click on "Rover" parts). They also have a complete set of all required gaskets for a head gasket job for only $128.90! Head gaskets in all these sets are composite material with steel reinforced head bolt and cylinder bore holes.

Intake Manifold Gasket:
This is an item that has had to be replaced innumerable times at considerable expense on my 4.0SE. I recently found out that SpeedyCarParts.com (click on "Rover" parts) stocks the intake manifold valley gasket for only $11!

Main and Rod Bearings:
Aftermarket rod bearings are now available from Atlantic British for $84.95 per set. I found a British-made set of 4.0/4.6 rod bearings at SpeedyCarParts.com (click on "Rover" parts) for only $39. Their main bearings are $82 per set with free shipping.

Timing Chain:
An aftermarket timing chain is available from Atlantic British for $50. SpeedyCarParts.com (click on "Rover" parts) has it for $36. The timing cover gasket needed if you are doing this job is $10.84 from the same supplier.


Exhaust System Range Rover 4.0 / 4.6 /P38A

Catalytic Converters:
These are expensive items to replace, and all 4.0/4.6 models have a single piece Y pipe with both converters that comes as a single unit. The genuine part number is ESR4095 for model years through 97 (cost so high you are afraid to ask). With this in mind, Atlantic British developed their own replacement for this part using quality aftermarket cats and stainless steel pipes. This should last longer than the genuine part, and is priced at $699.95. The Rover Connection lists an aftermarket replacement for the Y pipe and cats for $550. SpeedyCarParts.com lists the combined Y pipe and converters in stock (49 state) for $504.67 (with free shipping, which is a significant factor on such a bulky item).
The lowest price I have seen to date is at Discount Converters Ltd of Houston, Texas, which lists a 49-state replacement part number ROVqq09 for the 4.0/4.6 that includes both left and right converters for $432.95 plus shipping, and a 50 state system for $489.95 plus shipping.

Complete Cat-Back Exhaust Systems:
I found a complete cat-back replacement exhaust system at Atlantic British for about $400 -- a savings even on discount aftermarket pricing for the separate items (see below). aftermarket Borla makes a performance enhancing exhaust system for the 4.0/4.6, available through Atlantic British for $799. Northwest Rover Performance is also working on a system for the 4.0/4.6. Note that these high performance systems can increase noise and resonance at certain speeds.

Mufflers, Center and Rear:


(For full details on replacement of the center and rear mufflers, and the parts needed, see the 4.0/4.6 muffler replacement page)

Center Muffler:
The genuine center muffler and associated tubing is available from The Rover Connection for $185. One is now available from British Pacific (ESR3195, MY 95-97) for $179 and from Atlantic British for the same price. Atlantic British carries the largest selection of 4.0/4.6 exhaust replacement options I have seen, including stainless steel replacements with lifetime warranties.

Rear Muffler(s)
1995-96: Up through 1996 there was only one rear muffler -- the genuine part ESR3538 is $260 from The Rover Connection. The lowest price I have seen so far is for a replacement from Atlantic British for $239.
1997-2002: For these model years there were two rear mufflers. The genuine complete tailpipe/muffler assembly ESR4126 retails for about $400, but can be ordered from The Rover Connection for $280. The lowest price I have seen for rear muffler replacements for these model years is at SpeedyCarParts.com who have the mufflers available as separate parts for only $96.20 each.


Filters Range Rover 4.0 / 4.6 /P38A

Air Filter:
The air filter setup for the 4.0/4.6 is different from the Classic; the genuine part number is ESR341, and the FRAM number is CA8009, Wix number 42272. Alex Schubow reports the genuine filter from the dealer cost him less than the aftermarket ones for the 4.0 engine! (I have found prices from aftermarket suppliers are generally about $12-15). The 1999 and later models with the Bosch intake system have a different-looking air cleaner housing, but it takes the same filter element. For those who wish to try the K&N re-usable filter system, the K&N part for all Range Rover models is the HP2004.

Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics) and the Wix number is 33481. Atlantic British sells a generic filter for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30. I found the FRAM one at partsamerica.com for only $11.99!


Oil Filter:
The Rover V8 is known for losing the prime on the oil pump so it is important to get a filter with an anti- drainback valve. The oil filter used on the 4.0/4.6 is the same as on earlier Range Rovers; FRAM lists the PH16 as a suitable substitute. I found this one at partsamerica.com for $4.49 (October 2004). Alex Schubow reports that Genuine Land Rover oil filters are made by Wix. Paul Supp looked it up on the Wix site and the part number is 51068. A few years ago, Alex bought various substitute oil filters at auto parts stores, finding that prices for Bosch were around $3-4, AC were around $3, Mobil-1 were around $5-6. Bruce Powell uses a PH8A instead due to a larger size in height thus holding a bit more oil which he feels might be better for cooling too. A great deal of information on different oil filters can be found at this link.

Pollen Filters:
For quite a while, genuine pollen filters (BTR8037) were less expensive than aftermarket replacements. Now they are both about $14 each from most mail order houses (2 required).


Transmission Filter Kits: Every 30,000 miles the transmission filter is supposed to be changed. (For details on this operation see the 4.0/4.6 transmission service page). The kit to do this, complete with new gasket and O-rings, can be obtained from aftermarket sources such as Atlantic British sells it for $59.95 and SpeedyCarParts.com (click on "Rover" parts) for $36.09. The lowest cost I have seen so far (October 2004) was at partsamerica.com where they list a generic substitute kit for $17.47!


Fuel Delivery System Range Rover 4.0 / 4.6 /P38A

Fuel Filler Cap:
Land Rover Part Number NTC5418: This is one part that is cheaper than the Classic equivalent! I was surprised to find it at Atlantic British for only $11.95. If you are willing to try generic parts (at your own risk -- I don't know if they have the correct air and cacuum venting -- let me know how they do!!) Stant lists the 11819, available from Kragen, Schucks, Checkers etc through partsamerica.com for $7.38. ExpressAutoparts.com lists it for $8.44, and an even lower cost Gates equivalent (#31612) for $6.34!! To find these, click on their "Cap (gas/rad/oil)" parts category.

Fuel Filter:
Genuine: The genuine fuel filter is available from The Rover Connection for $28.
Generic: FRAM part number is GS3727 (Same as for the later Classics). Atlantic British sells a gneric one for $21.95. A Bosch equivalent is available at the SpeedyCarParts.com (click on "Rover" parts) for $13.02. The FRAM filter is listed at ExpressAutoparts.com for $12.30.

Fuel Pump:
Model years 1995 thru 1997 use part number STC4344. The genuine Land Rover part now costs about $360. The best price I have found for a full "plug & play" replacement (April 2004) is $299 at British Pacific and from Atlantic British for $289, including the necessary ring seal for the top of the pump (a $12 item). You can also get the complete assembly minus the seal from SpeedyCarParts.com (click on "Rover" parts) for about $300 with free shipping, which may work better depending on shipping costs. Evan Amaya reports finding a generic equivalent -- the Airtex E3270 -- which worked perfectly for him and only cost him $100 at a local auto parts store. Like the generic replacements for the Classic, this is the pump and motor only, and has to be installed in the original mounting assembly. (See photos on 4.0/4.6 fuel pump replacement page). This pump was used on a number of GM cars. I found this pump at partsamerica.com for $96.99, and the same thing in the "Master" brand for only $74.99 (search for "E3270" on the partsamerica site).


1998 and later models use part number STC4345 which is more expensive -- the best price I have seen for the genuine part is $380 from The Rover Connection. However I was surprised to find it recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $295 with free shipping.

Fuel Pump Relay:
I found this for only $7.95 at Atlantic British

Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.


Fuel Tank Cap:
The genuine gas tank cap is available at The Rover Connection for $27; I found a replacement for this at SpeedyCarParts.com for $18.


Inertia Switch:
This turns the fuel system off in case of collisions. It is an expensive part, but I found a generic version manufactured by Standard at JCWhitney.com for $56.44 (Click on "Replacement Parts"). ExpressAutoparts.com has a similar unit to fit the Range Rover for $57.79.


EFI Parts:
See Fuel Injection System section below.



Fuel Injection (EFI) System

ECUs:
Car Electronic Services can supply rebuilt engine ECUs for the 4.0/4.6. RPI Engineering offers ECU upgrades, available in the US through East Coast Rovers. Kelly Minnick discovered that a company called Superchips Inc produces performance upgrade chips for vehicles previously considered "unchippable". They developed an enhanced chipset for the Range Rover 4.0SE which requires 2 chips instead of one (due to the 4 coil ignition system) and boosts output by 19 bhp and 30 ft-lb of torque. The Rover Connection also lists a Powerchip brand performance chip for about $490.

EFI Parts:
Richard Keys of ATP Electronic Developments Ltd reports having a huge range of remanufactured electronic fuel injection parts available for all Range Rovers.

Fuel Injectors:
The fuel injectors on the 4.0/4.6 should be the same part as on the Classic; SpeedyCarParts.com (click on "Rover" parts) sells the genuine Lucas injectors for $102 each (free shipping), and Bosch replacements are available from Atlantic British for $99.95.
The lowest price I was able to find on a recent search (April 2004) at $599 for a set of 8 ($75 each) at Atlantic British.
Update June 2005: The lowest price I could find for individual injectors was $80 at British Pacific (part number ERR722, 95-98). However I recently discovered that Five 0 Fuel Injector Specialists have brand new warrantied OEM Bosch injectors for all RR models for $280 per set of 8 -- equivalent to about $35 each!! At these prices they do not sell them individually, just in sets. David Giller reports he got a set from them and they arrived in two days -- installing them completely cured his 1998 4.6 hard starting problem.


Fuel Pressure Regulator:
Most aftermarket suppliers do not even list this part, however I found a Lucas brand one recently (October 2004) at SpeedyCarParts.com (click on "Rover" parts) for $136 with free shipping.


Idle Air Control Motor:
This item (ERR4352) is not a constant troublemaker on the 4.0/4.6 as it is on the Classic, but on the downside it has certainly been known to fail and is even more expensive than the Classic equivalent. It seems to be the same part for all models including the later Bosch engines. Lee Schierbaum had a problem with this unit on his 1996 4.0 and instead of the $200-plus genuine item he located a NAPA replacement part (Echlin #2-1856) for $52. The part also fits a Jeep. Another part number I have seen for this is AC-151. Matt LeFande (September 2004) found an even less expensive replacement at partsamerica.com -- a Borg Warner 21774 for $39.95! They also have a Niehoff Ignition 21774 that can substitute.
If you would rather use a regular Rover parts supplier so you know for sure the unit will fit and work according to spec, the best price I have seen for this part (October 2004) is $139 at British Pacific (part number ERR4352).


Mass Airflow Sensor:
The OEM part for the 95-98 models is over $600, but I found a generic replacement for this part at SpeedyCarParts.com for $398 with free shipping. In 1999 the part changed for the Bosch engine controls, and I found the MAF sensor for these models at SpeedyCarParts.com for only $290.


Oxygen Sensors:
The US spec 4.0/4.6 has 4 Oxygen Sensors(one ahead of and one behind each catalytic converter), so replacing them all can get expensive. NOTE: If you get an aftermarket replacement, make sure it is a full 4-wire version, not a "4 wire to 3 wire" version -- see below. One useful source for looking up the sensors specified for the 4.0/4.6 is the manufacturer's website, NGK -- at www.ngk.com.

OEM "plug and play" replacements are available at The Rover Connection; the genuine O2 sensors for the 95-97 models (ERR1834) can be ordered from them for about $220 each, but they can supply aftermarket ones for $130. Sensors for the later models (AMR6244) are $180 from the same supplier. The lowest price I have seen for the OEM style plug and play sensor is $115 from automedicsupply.com (earlier model years); the lowest price I have found for the 1998 & up models is at Atlantic British which has OEM plug & play O2 sensors for $77.95 for the front ones (MHK100940) and $69.95 for the rear(MHK100930)!! (select their exhaust" category).


Michael Nix had the "Check Engine" light come on recently on his wife's 96 Range Rover. A trip to the dealer revealed confirmed that the engine had a slow oxygen sensor. Instead of paying the $275 from the dealer, he got one at a Nissan dealer for $90 (part number: 22690-85E10). He spliced the Range Rover connector on to the Nissan sensor and it fit perfectly. Three out of the four wire colors even matched up. I recently found this part by searching for its part number at SpeedyCarParts.com for $58.43!!

Alan Rawson delved more deeply into the O2 sensor problem on his 96 RR, adding substantially to our collective knowledge. He found the dealer price had dropped to $130. He found NAPA offers a similar item but with different connectors, their part # OS 778 (I recently looked it up and priced it at $81.99; it looks like the Nissan part mentioned above). Alan initially chose a Nissan part by NTK, which he found for $56 at a web company in southern CA., www.automedicsupply.com (their part # 250-2505). However, this replacement was a curious one with 4 wires at the connector reducing to 3 at the sensor. The vendor thought it would work fine, since the 4th wire is just data ground. All appeared to be OK at first, but Alan found that when the wires to one sensor were sheared off during an off-road trip the GEMS computer could not detect the problem (no light came on) and gas mileage went down the tubes. After further research, Alan found another part by NTK for $89.99 (current price $114.95 as of October 2003) which has the OEM connector (www.automedicsupply.com part number 250-8004) listed for the 4.0, quoted to replace OEM #70399A-- that number was stamped on his old original ones!). The 4th wire provides data ground, and with the semiconductor circuits used in the GEMS computer it appears to be important to have this separate ground, so the computer can detect failure of an individual sensor through the ground circuit. Ron Beckett checked the NGK manufacturer's website at www.ngksparkplugs.com and reports that their part number for the O2 sensor with the right plug for 95-98 models is 25017. Their UK site calls it a OTD3J-5C1, number of wires 4, connector style 57, lead length 521 mm. On Australian models a 3 wire unit is specified, OTD3G-3A1, with connector style 55.


Lowest Price (95-97 models): After scouring different sources for these parts, the best deal I have found so far was from a part number search for the Nissan equivalent 22690-85E10 at SpeedyCarParts.com (their part# C5010-65234) and found it there for $58.43 (free shipping). (To do a part number search on their site, go to the "Replacement Catalog" link on their main page). This is a Bosch part# 13388, and is the 4 wire version but with two connectors -- the wires can easily be spliced to the single Range Rover connector from your old part. For "Direct Fit" replacements with the OEM connector, the lowest price I have found is $114.95 at automedicsupply.com.(Click on year and make "Land Rover").
1998 & up models: the lowest price seems to be at Atlantic British which has OEM plug & play O2 sensors for $77.95 for the front ones (MHK100940) and $69.95 for the rear(MHK100930)!! (select their exhaust" category).


Ignition System Range Rover 4.0 / 4.6 /P38A

Coil Pack and Individual Coils:
The 4.0/4.6 uses a four-coil pack costing about $700-800. Usually only one of the four coils fails, but parts houses only sell the complete pack. Walter Gates recently reported spending $750 on new ones after his failed and caused misfiring and rough running. (For details of diagnosis and replacement see the 4.0/4.6 Ignition Coil Failure, Diagnosis &Replacement Page).I recently found the complete pack for $619.95 at Atlantic British. SpeedyCarParts.com (click on "Rover" parts) who recently had them (April 2004) for $621 with free shipping. Patrick Bennett has subsequently discovered that Car Cannibal can supply individual coils (used but warrantied) for about $60 each. Email me if you find a less expensive source!


Crankshaft Position Sensor:
This sensor's failure is often the cause of intermittent ignition problems. The genuine part is about $64; SpeedyCarParts.com (click on "Rover" parts) has it for $44.83. (search under "engine electrical - reference sensor") and I recently found an aftermarket one at Atlantic British for $37.95.

Ignition Leads:
A full set of aftermarket ignition leads cost around $50-60 from any of the sources I have checked. Email me if you find one for less! Update September 2004: I just found out that British Pacific offers a set of leads for the 4.0/4.6 models for only $39.99! This is part number GWS101 for the GEMS models (95 to 98) and GWS102 for the Bosch models (1999-2002). Use their part number price lookup feature to get current pricing and specials.
I recently found an aftermarket lead set from Nology that claims to boost horsepower. It is probably only a mild boost and there may well be other ways of increasing power for less money, but if you are interested see this link: Land Rover Range Rover V8 95-97 Nology HotWires

Spark Plugs:
The original equipment plug is the Champion RN11YC. Generic parts are Autolite 64 (available for about $1.45 each from Kragen or AutoPartsGIANT.com). SpeedyCarParts.com (click on "Rover" parts) lists many replacement alternatives from a $1.45 Bosch plug to a $13.61 Denso Iridium IW16 plug.



Radio


Range Rover sound systems are supposedly designed to withstand the rigors of off-road use but I personally have found they need replacing or repairing at regular intervals. For example, the LCD panel on the radio goes dim on one side if one of the bulbs illuminating it from behind fails. The procedure for replacing the backlight bulbs is detailed on the Radio Display Backlight Bulb Replacement page, but is a slightly tricky operation (sometimes resulting in further damage from the soldering iron such as burnt LCD microchips and connections). This and other radio problems can of course be fixed by paying the $1500 requested by the dealer for a new radio, but I recently discovered that John Monaghan of Roverville Radio Repair & Exchange provides top quality radio work with all genuine factory parts at a fraction of Land Rover's prices and down time. John specializes in the Clarion Diversity units (AMR 2672) used on all 4.0/4.6 models from 1994 through 1999.5, and the RTC7788 model used on Defenders. He also buys these units in any condition and sells fully reconditioned units for $425 (a far cry from the $1500 Land Rover price). He actually repairs these units for many Land Rover dealers who do not want to wait several months for the official Clarion repairs -- John's usual turnaround time is a splendid 24 hours from the time of receipt. John has kindly agreed to help sponsor this website, so if you use his services please mention you were referred by Rangerovers.net.


Scan Tools Range Rover 4.0 / 4.6 /P38A

TestBook:
This is the official Land Rover diagnostic system used by the nealer network. It is basically a custom touchscreen controlled portable computer that connects to the 16 pin OBD-II plug under the dash, but accesses many more vehicle functions than standard OBD-II systems. It basically accesses anything that is computer controlled, which is nearly everything -- the engine, transmission, transfer case, suspension, BeCM, ABS, cruise control, and on and on. Originally, the system was not even available to anyone outside the dealer network, making it doubly frustrating when you run into the notation "Refer to Testbook" in the factory repair manual. Even though "Testbook" is now available to the public as an official Land Rover part, most private owners and local repair shops cannot afford the $20,000 tariff for it, so aftermarket equivalents have been developed by other manufacturers to fill the void (see below).

Rovacom Diagnostic System:
The Rovacom system was the first aftermarket equivalent for the "TestBook" to become available. It is claimed to be even better than the TestBook. It is certainly more portable. It uses a rugged custom case and hardware with a 12 inch touch screen. It draws its power from the vehcile's diagnostic connector or a 12 volt jack. The unit comes with all the software installed for the various Land Rover models, but you can pay for only the ones you want activated. The basic unit with no software activated is about £2,000. Thus, you can get a system customized to cover all the systems on your particular Range Rover 4.0/4.6 for about £3700 ($6,000). Rovacom recently started selling used units for up to 50% off, bringing them down to the £4,500 range ($7300) for units with software activated for all models. In the US the Rovacom system is available through Rovers North ([email protected] and ask for Arthur or George) or British parts International (Phil Prince, [email protected]).
Update: In 2003 the "Rovercom Lite" system became available, allowing customers to purchase only the functionality they need for their own model, and run the software on their own laptop computer. This has brought the price down to the region of £600 ($1,000), which is getting within the reach of owners who may live a long way from the nearest dealer.

Autologic Diagnosis System:
The Autologic Diagnosis System is another aftermarket TestBook equivalent. In the US it is available through Atlantic British. Their price is $10,500 for a complete system covering all late model Land Rovers -- feasible for some local shops but not many individual owners.

OBD-II Scan Tools:
Standard OBD-II scan tools can give you much of the same information as TestBook about engine and transmission fault codes, although they will not let you diagnose some of the other systems like the electronic air suspension. Trevor Briggs and Kelley Minnick found an OBDII Automotive Scan Tool Browser for $122 from Alex C. Peper, 67 Scotch Pine Dr., Islandia, NY 11772. This generic OBD II software gives the basic readouts and can reset the various codes. (Choose ISO gateway router for Range Rovers, rather than the VPW or PWM versions for GM and Ford vehicles). It runs on any Windows 3.1, 95 or 98 computer, 386 or higher, and is optimized for low cost laptops. The system includes a protected RS-232 interface, OBD-2 connector and cable, world wide shipping, handling and taxes. You can actually download the "software only" for free, and make your own cable and interfacing. New browser features advertized include Land Rover, Nissan, Subaru defined test results.

Michael Nix went to Auto Zone and bought an Actron OBDII diagnostic tester to diagnose the oxygen sensors on his wife's 96 RR. (Actron's web-site is www.actron.com. Their latest hand-held Actron scanner is really convenient and works on all American and Imported OBD-II vehicles. It is sold thorugh JCWhitney.com for $159.99. On the older version Michael used (CP9035F), he found the codes had to read and reset with the engine running, which is contrary to what the manual said. Also, it took multiple tries to read the codes and reset the check-engine light.

Danny Ledford reports that TRW has a scan tool called the Laser 2000 that is very affordable. He says it does engine management, ABS, and electronic air, and works on new OBD-II and older serial ports.

The Lowest Prices I have seen for a full function hand-held OBD-II scanner for the 4.0/4.6 are $106.95 for the Actron CP9135 at Tradervar, and $114.99 for the Equus 3100 at partsamerica.com. This scanner works on all US and foreign vehicles. I saw the older, more basic Actron CP9035 (mentioned above) with only a digital numeric readout on sale at Tradervar for $59.95.


Sound System

See Radio section above.

Steering Range Rover 4.0 / 4.6 /P38A
Steering Damper:
OEM steering dampers are available from Atlantic British for $97.95 plus shipping (April 2004). The SpeedyCarParts.com (click on "Rover" parts) sells them for $82 with free shipping.

Power Steering Box:
This is not a weak point as it is on the Classic; however when it does fail it is even more expensive than on the older model. The lowest cost I have recently found (April 2004) for the brand new genuine part is $1195 from Atlantic British.-- this includes the core charge which is refundable.
The lowest price I have seen for a rebuilt 4.0/4.6 steering box is a remanufactured unit by Maval sold by SpeedyCarParts.com (click on "Rover" parts) for $353 with free shipping. However last time I checked this was no longer available -- please email me if you find a better one.


Power Steering Pump:
Until recently, the lowest costs I had seen on these were for rebuilt units from ExpressAutoparts.com for $216 and AutoPartsGIANT.com for $182.75 (both with free shipping). However more recently (April 2004) I found the steering pump at Atlantic British for only $119.95!!



Suspension Range Rover 4.0 / 4.6 /P38A
Air Springs (Complete)
Air Springs (Bladder Only)
Air Compressor
Coil Conversion Kits
Delay/Turnoff Timer
ECU
Shocks

Air Springs (Complete):
These used to be very expensive but have been coming down in price. The Rover Connection has the front spring for $150. SpeedyCarParts.com list it for $148.77 with free shipping. The same part is now available (April 2004) at Atlantic British for as little as $119.95.
The rear springs have a longer rubber bellows and are still somewhat expensive; they are $189.95 from Atlantic British and $280 from The Rover Connection. .


Long-standing aftermarket air suspension maker Arnott Industries has been active in developing replacement air springs for Range Rovers (the owner drives one!!). They have several options. Complete replacement air spring assemblies similar to OEM are $105 (front) and $169 (rear)! They also make an improved second-generation design (far superior to OEM), with crimped bellows attachments. These are sold in pairs -- $205 a pair (front) and $358 a pair (rear). Tey also make bellows-only replacements (see below). It is hard to believe for long-suffering Range Rover owners used to air suspension problems, but all Arnott part come with a Lifetime Warranty!! Typical of Arnott's quality approach is their detailed installation instructions, with photographs, on their website. Daniel Golenia of Australia reports: "I imported a set and they transformed the ride quality of the vehicle."
Car Cannibal offer new air springs complete with limited warranties for similar pricing.


Air Springs (Bladder Only):
An aftermarket US manufacturer and supplier, Arnott Industries (who make air spring components for other vehicles such as Ford cars) now sell a replacement rubber bladder only (you re-use the aluminum or plastic top and bottom of the spring) for $89 each for the front and $105 for the rear. These parts have a lifetime warranty. Typical of Arnott's quality approach is their detailed installation instructions, with photographs, on their website.
Recently, a US manufacturer of coil conversion kits, Strutmasters, started offering replacement spring bellows and has the lowest cost I have seen (February 2005) for them in the US. They sell the front bellows only for $79 and the rear one for $95. Their parts also come with a lifetime warranty. This is hard to believe for long-suffering Range Rover owewners, but this effectively put an end to expenses on new air springs!!


Another new option (May 2004) is an Australian company called Airbag Man who supply RR air bellows worldwide for front (their part # AB0001) and rear (their part # AB0002) of all Range Rover models. Their own specially made versions are produced by Dunlop (same factory as original units). This provides the assurance of performance at least as good as original (they state the Arnott's units, by comparison, appear to be quite short once aged). Their export price is A$110 - about US$80 for either front or rear bladders. (Prices for Australian customers are significantly higher due to local import duty and taxes). Airbag Man's rear bellows are longer than the factory units as the originals start to leak and fall off once aged; this also allows a small suspension lift as has been carried out by Hardy Neale of Australia recently.

Compressor:
The Range Rover air suspension compressor sells for $440 at the dealer (November 2003). It does wear out and at 130,000 miles mine needed replacing. Until recently it (like other air suspension components) has not even been listed by aftermarket suppliers. However searching around for a replacement for mine, I found it recently in the new Atlantic British catalog for $389.95, The Rover Connection for $385 plus shipping, and at SpeedyCarParts.com for $370 with free shipping (listed as "suspension pump").


I recently discovered that Airbag Man in Brisbane Australia sells brand new compressors to export customers for A$400 or US$300 for inexpensive worldwide shipping, They also supply a compressor service kit from the OEM manufacturer (Thomas Pumps) that includes new sleeve and piston/conrod assy, and sells for A$200.00 or US$150. (prices to Australian customers are higher due to local import duty and taxes).

When my compressor went out at about 140,000 miles I obtained a used one from a wrecker for $225. Subsequent traffic from Ron Beckett and others on the rro email list suggested the Range Rover compressor might be a generic Thomas pump, and after searching their catalogs I concluded it is their model number 315CDC5612 (specs available on the Thomas Pumps site at this link). This is a 1/5 horsepower model with a thermal cutout and is rated for intermittent duty up to 150psi (the pressure used in the EAS system). Independently, Abe Thietten found a Thomas 315 series compressor at Puma Sales for $109, but I am not sure if this is the exact replacement as there are at least 7 identical-looking models in the 315 range with different specs (only the 315CDC5612 can attain the necessary 150 PSI, and the "standard" 315 model only reaches 130).



However, Abe reports that he found a better alternative at the same company, the more powerful 1/4 horsepower Blowjax DC2000 for $99 that he says fits perfectly. (See the EAS compressor diagnosis, replacement and repair page) You can line up the bracket on old air compressor with the new one and drill two holes to attach, easy. Because of this compressor's slightly larger size, the lid to the EAS system will only attach on the front not on the back, but that is no big deal. For the air line, the old adapter screws directly into the new Blojax air compressor, but before you do this you will have to rotate the top cylinder head so it points backwards. This pump comes with a filter and it is located on the side; it fits into the enclosure with no modification. The Blowjax pump is rated for a 50% duty cycle as opposed to the 15% of the OEM part, but does not have thermal cutout protection. Therefore you need to ground the thermal sensor wire going to the compressor connector to fool the Range Rover suspension ECU into thinking the non-existent thermal switch is working. As a result, there is a possibility this pump could overheat, so use at your own risk (Abe reports it runs very cool however). When using all these generic replacements you will also need to re-wire them using your old connector.


For more information on compressor replacement with genuine and generic replacements, see the EAS compressor diagnosis, replacement and repair page.


Coil Conversion Kits:
For those who are tired of dealing with the EAS, several manufacturers and vendors now offer coil conversion kits for the 4.0/4.6 models. Atlantic British offers a kit with aluminum perch adapters, instructions, a specially developed EAS override module to eliminate error mesages, and coil springsdesigned to ride at standard height, for $849. They also sell a heavy duty off road version with a higher ride height for $949. I recently discovered (Sept 2004) that British Pacific has developed a heavy duty conversion set, which has upgraded Old Man Emu springs, hardware and instructions, and their EAS override 'black box' to tell the BECM computer that everything is fine. Extensively road tested. Vehicle height just a touch higher than the middle setting on the air suspension. Uses existing shocks. $799.95.
A new development in this field is the Arnott Industries coil conversion kit, also using existing shocks, for $579. Typical of their thorough approach, their spring seats are CNC machined from solid 6061-T6 aluminum alloy, and the mounts are designed to bolt directly to the current suspension brackets. The kit features powder coated variable rate coil springs made in the USA, and includes step by step instructions on how disarm your EAS alarm. Strutmasters makes a simpler kit with fewer components for $495.


More information on this topic can be found on the 4.0/4.6 Coil Conversion Page.


Delay/Turnoff Timer:
(ANR4652): This part supplies power to the EAS ECU, and controls the periodic activation of the system even when the ehicle is unattended. On inspecting mine I found it is made by TRW, whose part number for it is 51606A0A. It therefore ought to be available from some other source -- please email me if you find one!


EAS ECU:
My parts manual states ANR3773 was used up to mid 1995 (VIN #MA308966). After that, it was ANR4499. David Sparks reports (November 2004) that the earlier versions are no longer priced, presumably meaning they have been replaced by the third version (RQT10040). If you buy this part new, it is the third version you would be quoted for.
Rovers North lists the regular price of the ECU as $392.13, but has them on sale for $159. (They use part number RQT10040). Another good source for ECUs is Car Cannibal, who specialize in recycled Rover parts and warranty everything they sell.

If you tire of the OEM system, Dakota Digital makes a complete air suspension control system for $795 including a remote control option. It does all the automatic ride height functions, as well as lets you control each bag individually. It also comes with a nice display to let you know what's going on. If anyone tries this, please email me so we can share your experiences with other owners.

Shocks:
The lowest price I have seen for the genuine shocks is at The Rover Connection for $90 each.
Various aftermarket shocks are available for the 4.0/4.6. Probably the most popular upgrades are the famous Bilsteins; these are now advertized at SpeedyCarParts.com (click on "Rover" parts) for $96 with free shipping. Kevin Kelly found them at www.shox.com which sells them for $314.80 for a set of four. Atlantic British offers aftermarket Boge replacement shocks for $89 each or $279 for a set of four. SpeedyCarParts.com also has an aftermarket shock by KYB specified for the 4.0/4.6 for $70. (free shipping). AutoPartsGIANT.com offers some KYBs for about $64 front and $61 rear (search for a late model 4.0/4.6 such as 1998). Brent Wilhelmi found Monroe Wilderness 4x4 shocks (RS010 front, RS001 rear) for his 4.6HSE for $62.95 each at DAP Enterprises.
The lowest price I have seen for 4.0/4.6 shocks is at British Pacific who offer their version of the "original type" shock for only $52.50 under part # STC3672 (front) or STC3671 (rear).


Transfer Case

I have yet to see new 4.0/4.6 transfer cases offered by aftermarket parts houses. One temporarily offered a rebuilt unit for $2,300 but they are no longer available. Recently (Feb 2004) I was surprised to come across rebuilt and fully warrantied (12 months and unlimited mileage) units at Car Cannibal for only $1,850. They even have rebuilt examples of the Callaway T-case (which was uprated for more torque and power) for $2,150.

Transmission Range Rover 4.0 / 4.6 /P38A

Rebuilt and Used Transmissions
Rebuilt ZF electric shift automatic transmissions for the 4.0 used to e extremely expensive, when available at all. However, I was recently amazed to find rebuilt units available from Car Cannibal for only $2,195 with a 1-year unlimited mileage warranty. The 4HP24 variant used on the 4.6 is $2,250.
Because the ZF transmissions used in Range Rovers are also OEM equipment in many other vehicles, some transmission rebuilding and parts houses also have them. Dwight Smith found a very low cost generic source of the electric shift ZF 4HP24 used in the 4.0 and 4.6 -- Phoenix Remanufactured Transmissions who have it for $1,250!! (You should check with them by phone for the minor variations for your exact application). Phoenix is a major rebuilding and parts house, and all their remanufactured transmissions are dyno tested and warrantied.


Used (not rebuilt) transmissions are another option -- I found they can be obtained from Car Cannibal for $850 for the 4.0 unit and $1,000 for the 4.6. Even these ones include a 6 month, 8,000 mile warranty!


Transmission Filter Kits:
Every 30,000 miles the transmission filter is supposed to be changed. Since the ZF transmission, with variations, is used on a number of other European vehicles, the filter kit to do this can be obtained from aftermarket sources. Atlantic British sells it for $59.95 and SpeedyCarParts.com (click on "Rover" parts) lists it for $35.


Washer/Wiper System Range Rover 4.0 / 4.6 /P38A

Headlight Wiper Blades:
Robert J N Watson reports that the little short wiper blades for the headlights (DKC100860) seem to be $13 each at the dealer or $26 for a set of two. He found that one 'narrow fit' blade for $3 can be sectioned to length to replace both! Ron Beckett bought a wiper blade at Kmart and cut the notches to fit the headlight wiper arms.
Washer System Pump:
The front windshield washer pump costs $57 from Rovers North. However, I found it for $15.33 at ExpressAutoparts.com!! (Select brand "Land Rover", and look in the "wiper" category. Part number is 65-01). I also found it for $14.99 at partsamerica.com. The lowest price I have seen for the same part was at JCWhitney.com for $12.95 (although it takes a lot more searching work to find it on their site!)

Windshield Wiper Blades:
Genuine wiper blades are expensive; even The Rover Connection charges $15 each for them, and the cheapest aftermarket ones offered by Atlantic British cost $12.95 each. I found Bosch replacements at SpeedyCarParts.com (click on "Rover" parts) for $8.42 each (in their body electrical category), but ExpressAutoparts.com have AC-Delco replacements for $4.01 each!!!


Wiper Blade, Rear:
This is a different part on the 4.0/4.6 -- Atlantic British sells an aftermarket one for $12.95, but I found Bosch replacements for $5.45 at Speedycarparts.com! (in their body electrical category).

Wheel Bearings Range Rover 4.0 / 4.6 /P38A

Genuine and Aftermarket Parts: The Range Rover 4.0/4.6/P38 had new lighter, stronger and simpler axle assemblies. The wheel bearings are pressed into the hub, eliminating the need for the inumerable seals, gaskets, washers, spacers and other paraphenalia that makes the reassembly of a Classic hub impossible without referring to a diagram. The only downside is that the procedure for replacement of the wheel bearings, according to the shop manual and Land Rover dealers, is to replace the entire $500 hub assembly as a unit. The lowest prices I have seen for these assemblies are at Rovers North, which has the rear hub assembly (FTC3223) for $466, the front left (FTC3243) for $469 and the front right (FTC3226) for $499. However Atlantic British now has a much less expensive solution -- they can sell you just the bearings already (part number FTC1507) for $199. In this case you need a means of pressing the old bearings out of the hub and the new ones in.
Generic Parts: When replacing my right rear hub assembly (see hub and bearing replacement page), I found the inner bearing was a Timken unit inscribed with part number NP275832. It also had a "DV" symbol on it, and was made in France. (I think front and rear use the same bearings). Andy Cunningham (at this link) describes the numbers printed on the boxes of Joe Godfrey's Timken bearings he got from Kaid Ltd in the UK for about GBP80 ($150). These were NP275832 followed by "90VA1" or "90UA1" (unclear). Also on the boxes were the numbers 200304 FR and 64922. DAP Industries sells an equivalent as partnumber FTC-3223B for $110. Recently, (January 2005), I found replacement bearings at Speedycarparts.com, who specify SKF bearings for front or rear (2 per wheel needed) for $28.76 each or $57.52 per wheel.
If you have tried using generic parts for this job, please email me!!).

Please email me if you have any other information on replacement parts for the 4.0/4.6.

Holy crap!!!:D

Thanks for all the info!:drink1:

If you are having intermittant sagging but the system still works (all 4 raise and lower) then you only have a leak. This can be repaired for less than $20 in o-rings. Dealers do not repair any of the parts, they will just replace with new. You can bascially rebuild the entire EAS system for about $500, which includes rebuilding the compressor, all new o-rings in the valve block and in all fittings, and all new air springs. Of that $500, $400 or so is for the springs, about $80 for the compressor rebuild kit, and about $20 for all the o-rings. I suggest you contact shupack on the rangerovers.net forums. He can supply the o-rings, compressor rebuild kit, and even rebuild your compressor and valve block if you wish him to. New bellows for the springs can be had from Arnott Industries

Your A/C problem is most likely blend motors. You can buy the set of 3 for about $150, and with some patience replace them yourself with the excellent writeup on rangerovers.net.

super simple

How involved is it to have the suspension system changed? I know nothjing about the process. Do I need to order the parts? If so, what do I need to get?
Hey, I bought a Strutmaster's conversion w.2in spacers for about $600, I did it because my compressor went and was gonna be like $500 to fix. The air suspension always seems to give you problems when you least expect it. The conversion was insanely easy to do, I was blown away by how easy it was to removes the air springs! the only you'll need to do is rent a set of spring compressor's from a local auto store. The back springs you have to fight in, but once it's done it's done so that's nice, then I had a shop re-wire my EAS system so that the error codes didn't show anymore. I had Rover Automotive in Durham do the re-wire, I wanna say it was $150 which is way less than the $400 box atlantic brittish sells. Then you can enjoy never having a suspension trouble again, and teh strutmaster springs ride great! just as smooth as the air, but way better in cornering!
