| 1. Establish the car on an equal horizontal platform. |
| 2. Start the engine and warm up a liquid of the amplifier of a steering to temperature 50~60°C. Turn a steering wheel from an emphasis against the stop some times. |
| 3. At engine work idling turn a steering wheel from an emphasis against the stop some times. |
| 4. Check up that in a tank of the amplifier of a steering there is no foaming. |
| 5. Switch off the engine and check up a difference of levels of a liquid in a tank at the working and switched off engine. |
|
The prevention
If a difference of levels of a liquid more than 5 mm, remove air from a hydraulic drive of the amplifier of a steering.
If liquid level suddenly raises after engine deenergizing, the further prorolling of a hydraulic drive of the amplifier of a steering is not required.
Incomplete prorolling of a hydraulic drive of the amplifier of a steering leads to occurrence of the noise published by the pump and reduces durability of work of the pump.
