On the 4 cylinder Saturn, follow the top radiator hose back to the engine. Note that there is a housing that is bolted to the engine to which the radiator hose is connected. Remove the radiator hose first, then remove the housing. On the 4 cylinder Saturn's, the thermostat is a part of that housing.
