Opel Corsa B 1993–2000 Service and Repair Manual: Power-assisted steering - bleeding

1. After any of the hydraulic unions has been disturbed, or if the fluid level has been allowed to fall so low that air has been introduced into the system, bleeding should be carried out as follows.

2. Top-up the reservoir with fresh clean fluid of the specified type. Fluid drained from the system must not be re-used.

3. If the pump is dry, start the engine momentarily and then switch it off. Top-up the reservoir to the lower mark on the dipstick, run the engine briefly again and repeat the process until the fluid level stabilises. It is important that the pump is not allowed to run dry.

4. With the engine running at idle speed, turn the steering wheel approximately 45º to left and right of centre, then from lock to lock. Do not hold the wheel on either lock, as this improves some strain on the hydraulic system.

5. Switch off the engine and correct the fluid level.
