General Information: Notes
Power steering pump is not designed to be serviced. If a customer has reported a problem, determine cause via the pressure test and leak test. If there is a problem, replace the power steering pump.
Oil circulation in Right Hand Drive (RHD) vehicles is identical to Left Hand Drive (LHD) vehicles except that the hydraulic lines are routed from left to right at the steering gear.
NOTE:
- If power steering fluid is low in the reservoir, check the steering system for leaks.
- In case of leaks near line connections, check lines/line connections for proper seal, if necessary tighten and wipe dry.
- Replacement pumps from the distribution center do not contain any fluid. Before installing, fill pump with G 002 000 hydraulic oil and turn pump by hand. Otherwise, the pump may be noisy when operating or may even get damaged.
- Oil type: G 002 000 hydraulic fluid
