Check of level of liquid of system of hydrostrengthening of a wheel


1. Periodically check liquid level in system of hydrostrengthening of a wheel in order to avoid emergence of problems with management of the car, such, as damage of the steering pump. Act as follows.

Do not hold a steering wheel povyornuty against the stop in this or that party more than five seconds. It can put out of action the steering pump.

2. The tank of system of hydrostrengthening of a wheel is located in an impellent compartment and has an unscrewing cover with built in in it measuring the shchupy.
3. Park the car on an equal platform and cock the parking brake.
4. Engine 112: Remove the left hose of absorption of air.

5. Turn to the left on 1/4 turns a cover (1) and take out the index of level (2).

6. At cold oil its level should be between marks of "MIN" and «MAX» (3/4) indexes. Cold it is considered oil if its temperature makes approximately +20°С.
At warm oil (+80°С) its level should be between marks of "MIN" and index «MAX» (5/6).
7.При need in the tank should add liquid level. For addition of level use only new liquid as even the most insignificant impurity can lead to violation of work of hydraulic system.

If liquid level in the tank fell below a zone corresponding to temperature of liquid, the steering with the hydraulic amplifier of the steering mechanism is necessary for checking in a specialized workshop as liquid loss takes place. In this case it is not enough to be limited only to addition of level of liquid.

8. Insert a cover with the index and turn.
9. Engine 112: Fix the left hose of absorption of air.
10. At the working engine turn a steering wheel several times from an emphasis against the stop. Thus air will be removed from system.
