Removal air from the hydraulic system of the power steering (Opel Astra G)

The procedure is carried out at room temperature - do not bleed the system immediately after a trip.

1. Check the fluid level in the power steering reservoir, if necessary, adjust the level, bringing it to the MAX mark (see Chapter Routine maintenance).

If the need to adjust the level occurs regularly and frequently, you should try to identify the source of the leak.

TRW System

The liquid level measuring dipstick is attached to the tank cap.

1. Start the engine, then slowly turn the steering wheel from lock to lock three times.

2. Turn off the engine and check the fluid level in the reservoir. If necessary, make the appropriate adjustments

3. Start the engine again and, turning the steering wheel from lock to lock, listen to the sounds made by the steering pump - if the operation of the pump is accompanied by background noise, then there are air locks in the system and the bleeding procedure must be repeated.
