General Information

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 power steering pump.

If there is no fluid in the reservoir, then the steering system must always be checked 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.
Power steering pump is delivered without oil. Therefore, Hydraulic Fluid must be filled before installation and turned by hand. Otherwise, noises when driving or damage to power steering pump may occur.
