Buick 89017311 Engine Coolant Pump Kit

Disconnect the negative battery cable from the battery. Caution: On models equipped with the Theftlock audio system, be sure the lockout feature is turned off before performing any procedure which requires disconnecting the battery. Drain the cooling system. If the coolant is relatively new or in good condition, save it and reuse it. Remove the air cleaner if necessary. Remove the windshield washer reservoir and the coolant recovery reservoir, as necessary. Remove the serpentine belt and tensioner. Remove the alternator and its brackets and the air conditioner compressor, as necessary. Remove the exhaust manifold heat shields and the exhaust manifold. Remove the radiator outlet pipe-to-radiator pump cover bolts, leaving the lower radiator hose attached. Pull down on the radiator outlet pipe to disengage it from the water pump and detach the pipe from the oil pan and transaxle. Remove the water pump cover-to-cylinder block bolts. On 3.1L engines, remove the small belt guard just above the water pump. Remove the bolts/nuts and detach the water pump from the engine. Clean the fastener threads and any 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 water pump mating surfaces with lacquer thinner or acetone. Carefully attach the pump and gasket to the engine and start the bolts/nuts finger tight. Tighten the fasteners in 1/4-turn increments to the torque figure listed in the Specifications. Don't overtighten them or the pump may be distorted.
