Power Steering Pump

3.8L Vin K:

A constant displacement vane-type pump provides hydraulic pressure and flow for the power steering system. The pump (32) is located on the engine and is belt driven by the power steering pulley (31). The major components of the pump (32) are the drive shaft, pump housing, pump fitting, flow control valve and spring, thrust and pressure plates, pump ring, rotor and vanes. The power steering system has a remote reservoir (10). The reservoir cap (24) has a fluid level indicator attached to show the fluid level in the reservoir. The bore at the front of the housing contains the flow control fitting, working with the flow control valve and spring, it limits the maximum flow of the pump (32). The pressure relief valve, inside the flow control valve, limits the maximum pump (32) pressure. The flow control valve, spring and pump fitting are located in the casting boss that runs across the housing.
