Thermostat HELP!
Well this may be the dumbest question I have ever asked, so here we go. I am replacing the t-stat on my gs3 and the previous owner used silicon for the gasket. I just got a new t-stat and rubber gasket but and my question is does the t-stat go on then the gasket or do I put the gasket on then the t-stat???
Because I tried to put the gasket on the housing the the t-stat tightened it down filled and burped the system and it is leaking front the housing!! UGH
Thanks for the help

You don't necessarily have to search in these forums. This is a typical job when installing a t-stat. With the housing off, install the t-stat with the hole in the "up" position. Completely scrape all of the old gasket sealer off the housing (likely your problem) then lay a thin coat on on the outer edges of the housing. I tend to add a thin coat to the other piece of the housing (attached to the block). Wait a few seconds then attach it and bolt it up.

I just did my t belt, so I know the feeling. The gasket actually wraps around the tstat, it doesn't go before like I had thought, I did that and it leaked coolant immediately. The gasket is thick and has a groove made for the tstat to fit around. Look at the gasket very closely and you will see what I mean.
Btw, I didn't use any silicone, sealant, I just followed the manual to the T. Good luck!

wbmx1981 is exactly correct,i did the thermostat yesterday.the gasket has a groove that actually goes around the thermostat.just make sure to dry everything good and place the gasket properly and you wont need any gasket sealer or silicone

dammit! Thats what I was wondering because it actually fit better with the gasket over the t-stat. Well I used a little sealant and it worked great. Hopefully it will be fine and next time I will know.
Thanks for the help guys.

You all had me worried there for a minute, with all this talk of a sealent for the t-stat. I changed my t-stat a couple of days ago. I haven't started the car yet so I don't know if it will leak. I did realize that the gasket fits around the the edge of the t-stat rather above or under it. So, I am reasonably confident that it will not leak. But, thanks for making me double-check.

I used the gray sealant and applied a thin coat to the outer housing. The t-stat will hold in place while you apply the sealant to the housing. Never had a leak. I never trust anything other than the gray sealant.
