Chevy Monte Carlo

Where is the thermostat on a 2002 Monte Carlo?

generally located where the upper radiator hose meets the block, under the throttle body

Follow the upper radiator hose to the engine, there should be the thermostat housing. And there is no drain plug on an 2002 Monte Carlo 3.8 v6 , so you will lose less antifreeze if you just disconnect the upper radiator hose from the thermostat housing then hold that hose up. I only lost maybe a quart of antifreeze.
