The thermostat is located right on the front of the engine block. It is not a normal thermostat like you see in most vehicles. It is actually the flange that the lower radiator hose slips on to. Drain your engine coolant, remove the clamp on the lower radiator hose going to to the motor. remove the two 10mm bolts from the radiator hose flange to the motor, and the entire assembly will come out. when you purchase a new thermostat, it will come already mounted in a new housing. Replace the gasket, place the new thermostat in the motor, and reinstall the bolts.

The Thermostat is inside the goose neck, just follow the hose from the radiator to the goose neck, unbolt the goose neck. Look inside the goose neck and you will find the thermostat.

Follow the top radiator hose to the engine, what that mounts to is the thermostat housing, remove this and there is your thermostat. * ** *** **** ***** Actually, on my 1997 SL2, the thermostat is on the bottom radiator hose. I would check the "Saturn Thermostat Pictures" link below, which also has installation and removal instructions.
Inside the fuel tank.
