Overview - Hydraulic Line, Reservoir, Vehicles With 6-Cylinder Diesel Engine, Vehicles With Dynamic Steering

WARNING: This page is about a different variant/trim than selected.

The Power Steering Pump Is Not Designed To Be Serviced. If There Are Customer Complaints, The Cause Must Be Determined Using A Pressure And Leak Test. If There Is A Malfunction, Replace The Power Steering Pump.

NOTE:

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.

The power steering pump is delivered without oil. Before installing, fill pump with Hydraulic Fluid and turn pump by hand. Otherwise, the power steering pump may be noisy when operating or may even be damaged.
