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.
