Hey everyone ! New member, any help would b greatly appreciated. I don't have a manual yet & my 2006 Lr3 hse, V8 is giving me problems with the coolant. I started having problems one day i was driving thru town (20 mph) & i heard a bubbling noise then saw white smoke billow out from under the hood on the drivers side. I immediately pulled over & had it towed home. When this happened i glanced at the temp & it went from halfway all the way down 2 the blue line. so i got a ride 2 the Auto zone looking 4 some coolant & The men said I HAD 2 get the zerex, yellow-clear coolant due 2 the fact they won't b carrying my old coolant (orange-pink Peak) is Zerex ok 2 use for my Lr3 ?? I did a coolant flush, & ever since whenever I drive about 5 miles (under 35 mph thru town) the coolant starts bubbling (boiling??) Out of the reservoir cap. The temp never went above half way ( which I've read doesn't really mean it isn't over heating b cuz the gauge is crappy. & I don't have the tool they suggested getting 2 tell an accurate temp) I'm in the boonies & not near a dealership, so I've been going 2 a local mechanic. So far we replaced the coolant reservoir, the cap twice ( the 1st he ordered was a euro spare & I asked him 2 get a genuine cap), the Thermostat, the water pump, the T bleeder valve. & it's still boiling- bubbling out. At this point I'm ready 2 tear out my hair in frustration. We did the compression test twice 2 c if any hoses r leaky, that was fine. We did a combustion test twice 2 c if the head gasket is cracked & that didn't change color. Anyone out there have any suggestions ?
