Steering System, Checking for Leaks

• Following installation operations and with no hydraulic fluid in the expansion tank, the steering system must be checked for leaks.

- Remove the noise insulation.

- Start engine.

- Turn steering wheel in both directions to full lock and hold briefly.

This builds up the maximum possible pressure.

• To avoid damage to pump, steering wheel must not be held at stop longer than 10 seconds during this test.

In this position, the following components must be checked for leaks.

• Seal ring for steering pinion at the steering gear valve housing.

• All line connections.

• All wiring connections.

• Power steering pump

• Seal rings for steering rack.

• This test can only be performed with bellows slid back.

- Open the spring-type hose clamp and boot hose clamp.

- Slide back bellows.

If fluid is visible in steering gear housing and/or in bellows, steering gear must be replaced.
