So Fix it

The fuel pump to your Saturn is what pressurizes the gasoline in the fuel tank and sends it to the fuel injectors and then to the engine to burn. If you are experiencing problems while driving your Saturn, such as sudden bursts of acceleration when pressing on the gas pedal steady or if the fuel pump is making noise and/or leaking, then the pump may be faulty and need replacing. This is a task that requires additional and more advanced knowledge about automotive repair, specifically in fuel and exhaust systems.

Oldsmobile installed an integral rack and pinion power steering system on the 1986 Cutlass Ciera. A belt-driven power steering pump mounted on the front of the 2.8-liter engine supplies hydraulic pressure. Over time, the power steering pump can become worn and cease to deliver sufficient pressure. Allowing the pump to run low on fluid can also damage or destroy the internal components of the pump. Replace damaged or worn pumps to restore the full function of the power steering system.

Remove the blower motor ground terminal from the motor case, using a nut driver. Remove the blower motor retaining screws from the blower case, using a nut driver, and remove the blower assembly from the case.

2

Place the catch pan under the water pump area of the engine. Using a screwdriver, loosen the heater hose clamp at the water pump and then remove the hose from the pump nipple. Position the hose so that it will lose a minimum of coolant while remaining out of the way for the rest of the procedure.

3

Place the catch pan under the power steering pump. Remove the hydraulic lines from the pump, using a flare-nut wrench. Cap the lines with plastic caps or tape to minimize power steering fluid loss.

4

Loosen the front pump bracket-to-cylinder head bolts, using a ratchet and socket. Loosen the rear pump bracket adjuster nut, using a ratchet and socket. Push the bottom of the power steering pump toward the engine to loosen the pump drive belt. Remove the belt from the pump pulley. Finish removing the loosened bolts and nuts and then remove the pump from the engine.

5

Insert the smooth end of the threaded puller assembly into the center hole in the pulley. Install the split puller collar that most closely fits the size of the center boss on the pulley. Slide the outer collar in place over the split collar. Hold the bottom nut on the threaded puller in place with a wrench and turn the threaded puller clockwise by hand until it bottoms on the pump shaft. Turn the threaded puller using a ratchet and socket until the pulley separates from the pump shaft.

6

Remove the rear pump bracket and front pump bracket from the old pump, using a ratchet and socket. Install the front and rear pump brackets on the new pump. Tighten the rear pump bracket nuts to 35 foot-pounds, using a foot-pound torque wrench and socket. Tighten the front pump bracket bolts to 25 foot-pounds.
