1994 Chevrolet Beretta Parts Questions & Experts Answers

• Q: How to disconnect the negative battery cable and replace the water pump on 1994 Chevrolet Beretta?

  A: Disconnect the negative battery cable from the battery, ensuring that the lockout feature is turned off on models equipped with the Delco Loc II audio system before proceeding. Drain the cooling system, saving the coolant if it is in good condition, and for Quad-4 models, disconnect the heater hose from the thermostat housing to ensure complete drainage. For all engines except Quad-4, loosen the water pump pulley mounting bolts while holding the pulley, remove the drive belt, and then take off the water pump pulley. On 2.0/2.2 liter four-cylinder engines, remove the alternator and brackets. For Quad-4 engines, remove the exhaust manifold, then detach the radiator outlet pipe from the water pump cover while leaving the lower radiator hose attached, and remove the water pump cover-to-block bolts. For all models, detach the water pump from the engine, clean the fastener threads and threaded holes, compare the new pump to the old one, and remove old gasket material. Clean the mating surfaces with lacquer thinner or acetone, apply a thin coat of ATV sealant to the engine side of the new gasket, and to the gasket mating surface of the new pump before carefully mating them. Attach the pump and gasket to the engine, starting the bolts/nuts finger tight, and for Quad-4 models, lubricate the splines of the water pump drive with chassis grease and the O-ring on the radiator outlet pipe with antifreeze solution. Tighten the fasteners in 1/4-turn increments to the specified torque without overtightening, following the correct order for Quad-4 models. Reinstall all parts removed for access to the pump and refill the cooling system, then run the engine and check for leaks.
