As far as I know and have read there is a gasket that goes around the thermostat, the parts store argues everytime I ask for the gasket that I need an o-ring, and I tell them time and time again "Your an idiot, it's a gasket." Am I right or am I the idiot?

 

Can you print out this picture and show it to them......

 

the one on the right is the pontiac v6 and the one one the left is for a chevy v6

 

This is the thermostat seal in the case you are talking about this instead of the thermostat housing gasket

 

oh right o... thats the only one that showed up in a search at napa online

 

I told him to look into the felpro intake gasket set and locate the thermostat GASKET to see and he said all he "ever works on is 3.1 and 2.8's and he know's them better then anyone." I knew it was a gasket though, just doesn't seem like the oring would do a friggin thing. Thanks guys.
