Follow upper radiator hose to engine to locate thermostat housing.

REMOVAL:

With the engine cold, drain the cooling system.
Disconnect the radiator hose from the thermostat housing outlet.
Remove the thermostat housing outlet and remove the thermostat.
Using a putty knife, clean the gasket mounting surfaces.

If the thermostat is equipped with a pin valve, be sure to install the thermostat with the pin facing upward.
