General Information
The power steering pump is not designed to be serviced. If a customer has reported a problem, determine the cause via a pressure test and leak test. If
there is a malfunction, replace the pump.
‹› If the fluid is low in the reservoir, always check the 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.
‹› The pump is delivered without fluid. Therefore, the pump must be filled with hydraulic fluid before installation and turned by hand. Otherwise,
noises when driving or damage to the pump may occur.
Removing
‹› To prevent damage to the ribbed belt, check the alignment of the Air Conditioning (A/C) compressor and the power steering pump pulleys.
Check the ribbed belt alignment after replacing the following components.
