Filling and bleeding the servo system (Opel Vectra B)

The servo system must be filled and bled if individual components of the hydraulic system were replaced and therefore it was necessary to drain the hydraulic fluid. The drained fluid cannot be reused. ATF is filled, see chapter on lubrication.

With the engine not running, fill the ATF tank to the top.

Start the engine several times and immediately turn it off. After each shutdown, immediately add ATF to the lower mark on the measuring ruler. The hydraulic pump must not run dry.

With the engine running, slowly turn the steering wheel 45° in both directions two or three times, then from lock to lock twice. Do not hold the steering wheel at the lock for longer than 10 seconds.

Adjust the fluid level again.

About the correct liquid level see chapter on lubrication.
