Replacing the power-steering pump in a 2002 Pontiac depends on the type of system you have. Pontiac has two different power-steering pump systems: the regular power steering system and the TFE system with electrical actuator and fittings. Without the TFE actuator and fittings both pumps look the same, but the two will not interchange. You will need to know what model 2002 Pontiac you have. Your auto parts house can till you what system you have based on the VIN.
Remove the negative battery cable with a wrench and place it aside. Remove the upper strut housing tie bar if necessary for access. Remove the power steering serpentine drive belt and electrical plug on the TFE off as applicable. Remove the lower bolt from the mounting bracket using a socket and ratchet if necessary for access. Take off the inlet and outlet hoses from the power steering pump. Remove the reservoir hose only on the supercharged engine. You will need a flat-head screwdriver for this task.
Place the power steering pump pulley so the bolts can be accessed through the hole in it. Remove the mounting bolts, using a socket and ratchet, through the hole in the pulley. Take the power-steering assembly out from the bracket. If necessary transfer the pulley to the new pump with a pulley puller.
Replace the power steering pulley assembly before you install the pump using the pulley-install tool from your kit. Start the power steering inlet hose connection to the pump by hand. Replace the power steering pump assembly to the engine. Replace the lower bolt first, making sure the hose and heater pipe have enough clearance so they do not touch. If the two rub together they will make noise after the installation is finished. Replace the outlet hose to the pump, directing the hose under the engine harness and the heater hose. If the engine is supercharged it will be necessary to connect the hose from the reservoir.
Torque the power steering gear inlet hose to 20 foot-pounds and the hose clamp at the pump to 15 inch-pounds. Torque the pump mounting bolts to 20 foot-pounds. If equipped with a TFE pump, attach the connection. Replace the power steering drive belt or serpentine belt if you removed either. Replace the upper strut tie bar and torque the nuts to 18 foot-pounds. Replace the negative battery cable and fill the power steering reservoir with fluid. Bleed the steering system by starting the engine and turning the steering wheel right and left until all the air is out.
