Well it depends on the type of engine you have, but that only has to do with the thermostat's location. The Haynes GM manual #38025 has instructions on how to change the thermostat in section 3-3. Amazon has copies of it dirt cheap.
The Thermostat is located in the neck where the upper radiator hose connects to the engine. you have to take off the upper intake plenum to access this. Alot of crap just to change the thermostat. excellent design GM. Jamie
At the engine end of the top radaitor hose, under the thermostat housing.

Take it to a garage it's a big job cost me $300. to get it done have to tear half the motor apart. Idiot GM does it on purpose! Murray
Follow the top radiator hose back to the engine. The radiator hose connects to a housing that is bolted to the intake manifold. Remove the radiator hose the remove the two bolts that hold down the housing and the thermostat is right there.
