Ford F7TZ-8501-AB Water Pump Assembly

Squeeze the upper radiator hose while the engine is at normal operating temperature. If the water pump is functioning correctly, you should feel a pressure surge upon release.

Yes. For those models, you should also: Disconnect the negative battery cable and drain the cooling system. Remove the cooling fan and shroud. Remove the drive belt, pulley, and hoses from the water pump. Proceed to remove the water pump from the engine. Clean the bolt threads and threaded holes in the engine. Compare the new pump to the old one and remove old gasket material. Clean the engine and new water pump gasket mating surfaces with lacquer thinner or acetone. Apply RTV sealant to the engine side of the new gasket and the gasket mating surface of the new pump. Attach the pump and gasket to the engine, threading the bolts in finger-tight. Install the remaining bolts, tighten them evenly in 1/4-turn increments, and reinstall any removed parts. Refill the cooling system and check the drive belt tension before running the engine and checking for leaks.

You can inspect for leaks through the weep or vent holes and listen for a howling sound or feel for shaft wear by rocking the water pump pulley.
