Pontiac 19209288 Engine Coolant Pump Kit

Disconnect the negative battery cable. Drain the radiator. Reaching inside the radiator shroud, remove the bolts which secure the fan to the water pump hub. Remove the fan and spacer(if equipped). A thermostatic fan clutch must remain in the "in car"osition. If equipped with a two-piece radiator shroud, remove the upper half of the shroud for better access to the water pump. It is now necessary to loosen and remove all drivebelts from the water pump pulley. The number of belts will depend upon model, year.and equipment Loosen the adjusting and pivot bolts of each affected component (air pump, alternator, air conditioning compressor) and push the component inward to loosen the belt enough to be removed from the water pump pulley. Disconnect and remove all mounting brackets which are attached to the water pump. These may include on late model vehicles the alternator, air conditioning compressor, and power steering brackets. Disconnect the lower radiator hose, heater hose, and bypass hose at the water pump. Remove the remaining bolts which secure the water pump to the front cover of the engine. Lift the water pump housing straight out of the front cover and then away from the engine. If installing a new or rebuilt water pump, transfer all fittings and studs to the new water pump (If a replacement pump is used, transfer all hose fittings from the old pump to the new). Clean the gasket surfaces of the front cover completely using a gasket scraper or putty knife. Use a thin coat of gasket sealant on the new gaskets and install the new water pump. Place the pump into position on the front cover and secure loosely with the bolts. Do not torque-tighten these bolts until all brackets have been installed to their original position on the water pump. Tighten all water pump bolts to torque specifications. Install the engine components in the reverse order or removal,tightening the appropriate fasteners to torque specifications. Adjust all drivebelts to the proper tension. Connect the negative battery cable and fill the radiator with a mixture of ethylene glycol antifreeze and water in a 50/50 mixture. Start the engine and allow to idle until the upper radiator hose gets hot. Check for leaks. With engine hot, fill with more coolant mixture until the level is at the bottom of the filler neck. Install radiator cap and check coolant level periodically over the next few miles of driving.

To replace the fuel pump/sending unit assembly, start by relieving the fuel pressure and disconnecting the negative battery terminal. Remove the fuel tank or access cover from the trunk floor pan, depending on the model year. The assembly is held in place by a cam lock ring mechanism. Unlock the assembly by turning the inner ring clockwise or tapping the lock ring counterclockwise. Carefully remove the assembly from the tank, being cautious of the fuel level float and sending unit. Check the condition of the rubber O-ring and replace if necessary. Inspect and clean the filter on the fuel pump. If needed, separate the fuel pump and sending unit, being careful not to damage the rubber insulator and fuel strainer. To install, position the rubber gasket around the tank opening and guide the assembly into the tank. Turn the inner lock ring counterclockwise until the locking cams are engaged. Finally, reinstall the fuel tank or the fuel pump access cover.

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

A failure in the water pump can cause serious engine damage due to overheating.

The exhaust manifold heat shields and the exhaust manifold should be removed.

This is for the 3.8L engine
