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

Disconnect the cable from the negative terminal of the battery. Drain the cooling system. If the coolant is relatively new or in good condition, save it and reuse it. Detach the radiator hose from the water pump. On 1994 and earlier models, remove the left engine mount. Loosen the water pump pulley bolts. Loosen the water pump pulley mounting bolts then remove the drivebelts and remove the pulley bolts. On 2011 and earlier models, remove the timing belt and tensioner. On 2011 and earlier models, remove the alternator bracket from the water pump. Remove the bolts and detach the water pump from the engine. Note the locations of the various lengths and different types of bolts as they're removed to ensure correct installation. Clean the bolt threads and the threaded holes in the engine to remove corrosion and sealant. Compare the new pump to the old one to make sure they're identical. Remove all traces of old gasket material from the engine with a gasket scraper. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone. Install a new O-ring in the groove at the front end of the coolant pipe and lubricate the O-ring with coolant. Apply a thin coat of RTV sealant to the engine side of the new gasket and to the gasket mating surface of the new pump, then carefully mate the gasket and the pump. Slip a couple of bolts through the pump mounting holes to hold the gasket in place. Carefully attach the pump and gasket to the engine and thread the bolts into the holes finger tight. Note that the bolt that attaches the alternator brace is longer than the other bolts. Install the remaining bolts. Tighten them to the torque in 1/4-turn increments. Don't overtighten them or the pump may be distorted. Reinstall all parts removed for access to the pump. Refill the cooling system and check the drivebelt tension. Run the engine and check for leaks.
