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.
