Disconnect the battery's negative terminal and drain the cooling system. Detach the radiator hose from the water pump and remove the left engine mount for 1994 and earlier models. Loosen the water pump pulley bolts, remove the drivebelts and pulley bolts. For 2011 and earlier models, remove the timing belt, tensioner, and alternator bracket. Detach the water pump from the engine, noting bolt locations. Clean bolt threads and engine holes. Compare the new pump to the old one, remove old gasket material, and clean mating surfaces. Install a new O-ring in the coolant pipe, lubricate with coolant, and apply RTV sealant to the new gasket and pump. Attach the pump and gasket to the engine, threading bolts finger tight. Install remaining bolts and tighten in 1/4-turn increments. Reinstall removed parts, refill the cooling system, and check drivebelt tension. Run the engine to check for leaks.

If the water pump shaft bearings fail, there may be a howling sound at the front of the engine while it's running. Shaft wear can be felt if the water pump pulley is rocked up and down.

Clean the bolt threads and threaded holes in the engine to remove corrosion and sealant. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone.

If the water pump is defective, it should be replaced with a new or rebuilt unit.
