A service operation for the 3.8L engine start with draining the engine coolant. The first step involves disconnecting the upper radiator hose from the water hose connection followed by removing the thermostat housing by unscrewing the bolts. End the thermostat removal task then check and clean both the water outlet connection and the thermostat itself. 144 Acceptance Services requires users to dispose of the previous gasket before performing extensive cleaning work on both surfaces.
