Power Steering Pump, Hydraulic Pipes and Reservoir Assembly Overview






Power Steering Pump, Hydraulic Pipes and Reservoir Assembly Overview

The power steering pump is not designed to be serviced. If there are customer complaints, the cause must be determined using a pressure and leak test. If there is a malfunction, replace the pump.

If power steering fluid is low in reservoir, check steering system for leaks.

If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry.

Pump is delivered without oil. Therefore, hydraulic oil must be filled before installation and turned by hand. Otherwise, noises when driving or damage to pump may occur.
