No, You don't put anything on Head, Exahust or intake gaskets. CJ
actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a Ford master technician, you ALWAYS use silicone when replacing intake and head gaskets.

Where is the thermostat located on the 1995 Chevrolet Monte Carlo?
On the 3.1 LS model, the thermostat is in the intake manifold, just underneath the air intake, and between the exhaust crossover and the manifold. Trace the upper radiator hose back to a metal pipe from the engine, that is the thermostat housing. Replacing it means using a ratcheting box-end (10mm?) or open end wrench to start and finish, and fingertips for the rest, so NOT when the engine is hot! The thermostat fits horizontally into the manifold, and comes with its own molded gasket, which fits into a recess, and doesn't require gasket sealant. I just changed mine, so good luck.
