Disconnect the cable from the negative battery terminal. Drain the cooling system and save the coolant if it is in good condition. Remove the engine cooling fan assembly. Remove the drivebelt. For 2.7L V6 engines, remove the timing chain and guides. For 3.5L V6 engines, remove the timing belt. For 5.7L VS engines, remove the thermostat. Detach the radiator hose from the water pump and remove the idler pulley for the drivebelt. Remove the water pump from the engine, noting the locations of the bolts. Clean the bolt threads and threaded holes. Compare the new pump to the old one and check the impeller blades for corrosion. Remove old gasket material or O-ring seal. Clean the mating surfaces with lacquer thinner or acetone. Apply RTV sealant to the new water pump O-ring or gasket. Attach the pump to the engine and tighten the bolts in a criss-cross pattern. Connect the hoses and reinstall all removed parts. Refill the cooling system, run the engine, and check for leaks.

On 2.7L V6 engine models, a failed seal may direct fluid to the "valley" of the motor and eventually leak out the back side of the engine. In this case, suspect water pump failure before other major engine leaks first.
