How to Install a Water Pump on a 1995 Jeep Cherokee

81

A Jeep’s water pump can be bad even if you hear no noise emanating from it. The fins on the back of the impeller can corrode to the point where the pump is no longer effective. The only way to check is to remove the water pump. Also, do not mistake the sound of a squealing drive belt for a water pump bearing failure. If the drive belt is not making the sound, you should replace the pump.

Tools Used: Tools, Wire brush, RTV sealant, Gasket scraper, Acetone/lacquer thinner, Shop rags, Water pump gasket, Torque wrench, Power steering fluid, Wrench, Antifreeze

Install a Water Pump

Use a wire brush to clean the water pump bolt threads and threaded holes. Connect the heater hose to the water pump. Use RTV sealant on the threads. Remove traces of the old gasket using a gasket scraper.

Use acetone or lacquer thinner to clean the mating surfaces on the engine and water pump. Apply a coat of RTV sealant to the engine side of the gasket. Apply a layer of RTV sealant to the water pump side of the gasket.

Hold the gasket in place by slipping a few bolts through the mounting holes. Attach the pump to the engine. Tighten the mounting bolts manually. Install the remaining bolts. Tighten the bolts to 22 foot-pounds with a torque wrench in quarter-turn increments. Install the idler pulley.

Install the power steering pump. Tighten the bolts. Connect the return and high pressure hoses. Fill the reservoir with power steering fluid. Install the drive belt. Install the cooling fan and shroud. Tighten the bolts with a wrench. Fill the cooling system with antifreeze. Run the engine. Check for leaks.
