| There is no provision for repairing the power steering pump. If problems are reported, trace the fault by means of a pressure test and a leakage test. Renew the power steering pump if there is a fault. |
Note| t | Always check steering system for leaks if fluid level is low in reservoir. |
| t | If leakage is visible at the pipe connections first tighten connections and wipe dry, then check for leaks again. |
| t | The power steering pump is supplied without fluid filling. Prior to installation, the pump must therefore always be filled with hydraulic fluid and turned by hand. Otherwise, there is a possibility of pump damage or noise while driving. |
