Where is the thermostat in my 1993 Saturn
when you open the hood and look down, you see the radiator. the radiator is a flat thing with a fan ni a plastic cage attached to it. the radiator has two large rubber hoses connecting it to the engine. where the top large hose connects to the engine is the thermostat housing. so you have to drain the cooling system, take off that hose, remove the housing and the thermostat will fall into your hand. if your heater is not working, replacing the thermostat will not fix it.
