t-stat housing.
How many gasgets is used with the thermostat? I got one big blue that fits over the t-stat? Is there supposed to be one under it as well?
Thanks

One gasket is all you need. The gasket seals between the goose neck and the intake manifold, not directly on the stat. Some people don't use a gasket at all but use a bead of silicone that forms a gasket. If you use silicone be sure to allow 24 hours for it to cure before filling with coolant.
Good luck!! :cheers:

Right, place the t-stat into the depression in the intake base, install the gasket onto the base and then the goose-neck over the gasket.
You don't want any coolant to leak out of the intake, but if a little leaks around the t-stat into the engine it's no big deal, right.

Re: t-stat housing. (devilfish)
devilfish, I just went through the same thing after engine rebuilt.
First, I tried a silicon gasket which said do not use RTV(it was very thick, over .5 cm). I't didn't work. One of the Forum members explained that GM housings warp or bow. You need to check this with a streight edge. To fix this he said use a belt sander.
I threw out the $5.00 gasket and bought an $.89 gasket. RTV on both sides. Drove it after 12 hours cure(I know, I know, I should have waited 24).
I have over 300 miles on it now.
Hope this helps! :thumbs:
