Disconnect the negative battery cable.
Place a large drain pan under the radiator drain plug. Allow the cooling system to sufficiently cool down before opening the drain plug to avoid personal injury. Drain the coolant to below the thermostat level.
Disconnect the upper radiator hose at the thermostat housing.
Remove the thermostat housing bolts and coolant outlet connector of the thermostat housing.
Remove the thermostat assembly from the vehicle and discard. Discard the old thermostat gasket.

To install:

Clean all gasket mating surfaces.
Install the new thermostat in the correct position. If equipped, align the air bleed valve on top of thermostat to the vent recess in the water box (engine side) of the thermostat housing.
Dip the new new gasket in clean water and install on the water box surface of the thermostat housing.
Install the thermostat housing over the gasket and thermostat, making sure the thermostat is in correct position.
Install the thermostat housing bolts and torque to 20 ft. lbs. (28 Nm).
Reconnect the radiator hose. Tighten the radiator hose clamp.
Connect the negative battery cable.
Fill and bleed the engine cooling system.
Pressure test for leaks.
