Changing from dexcool to green coolant.

[PTSchram]

Nah, I'm just old and pay attention to silly worthless things (like molal freezing point depression and boiling point elevation), Reduction/Oxidation and the Kreb's cycle:-)

Everything I need to know, I learned in general chemistry, calculus based physics and financial/managerial accounting.

Maybe that dog drank some Dexcool?

Wait. Dexcool causes animal hair to grow in phallic patterns? That stuff is pure evil.
And freeking hilarious.

Forgot who posted this:

By this logic this very statement you make "i doubt manufacturers would produce anything that would cost them more money"...

and yes I know it's a whole nother ball game,....how about the misaligned oil pump on the '03s. It is a documented problem by the manufacturer and still,...they do not care. So, yes the manufacturer does make mistakes. Some cover it up if possible,...Toyota? Firestone? the list goes on.

Just curious, what does the Land Rover gurus say to use in the vehicles now? Dexcool? If not, why did they change back?

Depends. '03-'05 Rangies use BMW blue coolant, now they have a pinkish product.

So many colors. Orange. Green. Blue. Pink. It's like a rainbow of coolant.

PT: I was at the Biltmore House in Asheville today doing some training and two of the attendees were from the "Land Rover Experience" on the Biltmore property. One of the men was a 20 year tech person, probably along the lines of Disco Mike's background. Plus, he said he studied and worked at Land Rover's manufacturing location. I told him about the debate,...and his response was the intent was to use a longer lasting coolant with Dexcool. He gave no real reason for it being discontinued other than when air is introduced into the system, it had a tendency to coat the inner workings of the cooling system...and said they primarily use the "green" stuff now. He saw no problem in doing a flush, perhaps twice, and then using the green stuff with no ill effects. They use Range Rovers for the "experience" and they are 2012 models.

You mean dex cool doesn't eat thermostats, caps, gaskets, little babies and cause birth defects in dogs?

My h2o gasket went @ 70K my TB gasket @75k and my heads @ 80k. My wife ran dexcool in her car (cast iron block) for many many years with no problem. Lets make no mistake aluminum block engines are more fragile than cast iron blocks. Rover adding a trendy coolant to these things just teased the animals. If nothing else dexcool proved detrimental to these engines due to leaks in the system (these blocks are famous for that) and contaminating the dexcool... Why add such fragile coolant to an engine that leaks like a noodle strainer? Rover was in denial. End of story...

Just like swivel ball grease, Rover made these changes to satisfy folks who do not service their vehicles regularly, if at all.
Auto assemblers make changes to cut costs and make assembly easier.

They only need to last to the end of the warranty period.

Afraid not, but I hear cats walk sideways after a sip.

I have been following this post and I have a question. I am using Dex, I get out of the truck and have a slight coolant smell as I get out of the door. I have searched but can not find evidence of a leak. fluid level is dropping very slowly. What are the main problem areas that will produce a smell, cause very little evidence etc. ? This is my first Rover, what have I gotten myself into ? Thanks for your help !

Check your throttle body heater. Look for an orange crust around it and maybe some on top of the valve cover beneath it.

could be anywhere, Rent a pressure tester and pump up pressure in the system to try and make it leak. Some common leaks are, throttle body heater, any hose, water pump and headgaskets which often leak down back of the heads. Also, tiny cracks in the seams of the radiator can leak as well as the bleeder screw on top radiator hose. (Basically wherever dex-cool has eaten through)

[mtnance]

If and when you do the pressure test, be prepared with your new parts. You could cause a very slight leak to become just a tad larger. However, best to have that happen on your own time in the test area, not doing 70 mph, 70 miles away from anyone that might be able to order parts for you.
