There is no provision for servicing the power steering pump. If there are customer complaints, the cause must be determined using a pressure and leak test. If a malfunction is present, the power steering pump must be replaced.
NOTE:
- If the fluid level in the reservoir is low, the steering system must be inspected 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.
- Pumps from service parts inventory do not contain fluid. They must be filled with hydraulic fluid before installation and turned by hand, otherwise pump noise or damage can result in operation.
