Where is the thermostat located in a 1996 Pontiac grand am and is it possible for it to get stuck and your car overheat?

if it is a four cyl it is most likely under the passenger side of the engine at the end of the bottom radiator hose it is best to take of the exhaust manifold to replace it is possible that it can overheating if it it bad I have a 1996 Grand Am SE, and mine runs hot too. Its probably not the thermostat, if not, then try flushing the coolant system, or the radiator might be clogged up.
