Power Steering Pump: Description and Operation

Power Steering Pump

The power steering pump is not designed to be serviced. If a customer has reported a problem, determine cause via pressure test and leak test. If there is a malfunction, replace the vane 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.

• Replacement pumps from the distribution center do not contain any fluid. They must be filled with hydraulic fluid before installation and turned by hand, otherwise pump noise or damage can result in operation.
