EA82T - bubbling

timmo · Post by **timmo** » Mon Jan 15, 2007 7:02 pm

The coolant in the water pipe coming out of the top of the turbo seems to bubble when I switch the engine off after driving. Is this normal? Or is there some issue here? The temperature guage hasnt gone above 1/2 yet and I always let the engine idle for a few minutes before switching off.

if you have been on any sort of real boost in the last 10 or so min of driving you will find your turbo is still really hot and the water is actually boiling in the turbo at this point is also sucks cooler water in....

try letting the car sit for 3min before u turn it offf... will be better for your car as it will cool the turbo down and then you wont boil your water and oil in the turbo which will also damage how the oil protacts your car...

I think i have got that right if it makes sence... or get a turbo timer and turn car off and walk away as the car will keep runnign for a set amount of time and then turn off...

It does sound as if the water is boiling but still does it even if I leave it sitting for 5 minutes idling after driving. I'll try bleeding it and see what happens.

Half way on the average guage is close or at the boiling point with the cap off, the fan also comes on about half way. No bleeding is required on EA82T's.
The warning on most caps "Do not open when hot" should be heeded.
