Power Steering Pump

The power steering pump is a multivaned hydraulic pump. The serpentine accessory drive belt on the engine drives the power steering pump. The power steering pump provides the hydraulic pressure to the power steering gear.

The power steering gear uses the hydraulic pressure to assist in steering the vehicle. The power steering system uses a remote reservoir in order to make available more space in the engine compartment.

No repair procedures are to be done on the internal components of the power steering pump. The only serviceable components of the power steering pump are the power steering pump pulley and the pump itself.

Power Steering Pump Pulley

The power steering pump pulley in this vehicle is not serviceable. If the power steering pump pulley is defective, you must replace the power steering pump assembly.
