Potentially Missing Connection to Proportioning Valve of the ECO-Power Steering Pump when Exchanging Engines
When replacing engines on vehicles with an ECO power steering pump, the wiring harness on the new engine also has to be replaced. Order the wiring harness as outlined in Parts Information.
Note:
When replacing engines 272 or 642 on the above models, the connection of the proportioning value of the ECO-power steering pump may be missing on the engine wiring harness of the new or reconditioned engine.
Repair Description
1. Check to see if an ECO power steering pump is installed. The ECO power steering pump has an electrical connection (see Figure 1, arrow) and can also be recognized via the engine number (see Table 1).
2. If an ECO power steering pump is installed, replace the engine wiring harness of the reconditioned engine with the appropriate one in Parts Information.
3. If an ECO power steering pump is not installed on the existing engine being replaced, the wiring harness must not be changed.
Warning!
The ECO power steering pump must be connected; otherwise a too light steering feel can occur around the steering wheel center position at higher speeds, which could lead to diminished handling capacity.
