2. Manually turn the power steering pump pulley a few turns.
3. Make 5 or 6 full turns of the steering wheel left and right.
4. Disconnect the central high-voltage wire.
Caution: Do not locate the central high-tension wire near the fuel rail.
5. Make several short crankings of the starter while constantly turning the steering wheel left and right (five or six times within 15–20 seconds).
Attention! When removing air, it is necessary to constantly add fluid and make sure that its level does not fall below the lower position of the filter. If you remove air while the engine is running, air will be sucked in and enter the working fluid. Therefore, it is necessary to remove air from the hydraulic system only when the engine crankshaft is turned by the starter.
6. Connect the central high-voltage wire.
7. Turn the steering wheel right and left until the air bubbles in the power steering reservoir disappear.
8. Make sure that the working fluid is transparent, without cloudiness, and that its level in the tank corresponds to the normal position on the dipstick.
9. Make sure that the difference in fluid levels when turning the steering wheel left and right is insignificant.
Fig. 13.6. Checking the level of working fluid in the reservoir of the hydraulic system of the power steering: A - with the engine running; B - with the engine not running
10. Check that the difference in the levels of the working fluid in the tank with the engine running and not running is within 5 mm (Fig. 13.6).
11. If the level difference reaches 5 mm or more, it means that the air has not been completely removed from the hydraulic system, so the air removal operation should be repeated.
Attention! If the fluid level rises sharply after the engine is stopped, it means that the air from the hydraulic system has not been completely removed. If the air from the hydraulic system of the power steering is not completely removed, extraneous noises will occur from the pump and the control valve, operation in this mode will lead to a reduction in the service life of the pump and other elements of the hydraulic system.
