littlebear 0 Posted July 7, 2007 Changing my thermostat on the corrado has proven to be more of a chore then I expected. That thing is leaking like crazy. I changed the seal and RTVed the hell out of it and still it leaks anyone have any Ideas. I will post pictures and directions online as soon as I get her all buttoned up so if anyone else wants to take the challenge of thermostat changing they will at least have pictures to follow if they cant read LOL!!!

double-6s 0 Posted July 7, 2007 I've got an idea mate - buy a good 2nd hand one off me! :) Quote Share this post Link to post Share on other sites
littlebear 0 Posted July 7, 2007 I would but mine is really in good shape no need for another one. I think what happen was I did not let the RTV cure long enough and I may have not tightened the bolts properly so the housing may have not seeded right. Tomorrow I will get it all taken care up. But I will keep you in mind if I get pissed and throw it across the driveway and I need to get a new one!!! Quote Share this post Link to post Share on other sites
VEEDUBBED 0 Posted July 8, 2007 Bastid of a job,especially if working on your back on a jacked up car with stands..,you don't really need any kind of gasket goo,just remember to replace the plastic housing's O-ring and coat it in a little grease and make sure that the O-ring itself hasn't fallen off or been disloged while tying to relocate the housing in that god awful location. 1 other thing,make sure you use the correct length bolts on the aluminium PS pump housing that bolts to the engine block and don't over tighten them otherwise the longest bolt will just pinch the very edge of the plastic thermostat housing,dislodging the O-ring and cause a small leak,i learnt after stripping the fu$king thing down three times trying to see the cause of the mysterious leak...

VR6 0 Posted July 8, 2007 Sure it's not a crack in the housing? Quote Share this post Link to post Share on other sites
littlebear 0 Posted July 9, 2007 I don't think its a cracked housing but i will double check tomorrow when i take it off again. Quote Share this post Link to post Share on other sites
Supercharged 2 Posted July 9, 2007 You shouldn't need any sealant, if it gets into the sytem it could jam the stat - just make sure the mating face is clean and that you use a new (VAG) O ring... The housing may be warped if not cracked, they do this because of heat over time, especially on the G60 and VR engines as they run hotter, I would advise always changing the plastic flanges for new when working on the cooling system.

Dogzyboy 0 Posted July 9, 2007 Just changed the water transfer pipe at the weekend. That has to be the worst job ever....I've now got a small leak from the stat housing as it's warped from the heating & cooling it's received over the years. Gonna have to order me some new stat housing parts to stop the drip... Quote Share this post Link to post Share on other sites
