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.

INSTALLATION:

Install a new thermostat the gasket, O-ring or sealant (as applicable). Always install the spring end of the thermostat facing the engine.
Tighten the thermostat cover-to-thermostat housing bolts to 9 ft. lbs. (12 Nm).
Connect the radiator hose to the thermostat housing.
Fill, then bleed the cooling system. Check for leaks.
