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 turned against the stop in this or that party more than five seconds. It can put the steering pump out of action.


2 The tank of system of hydrostrengthening of a wheel is located in a motive compartment and has the unscrewing cover with the measuring probe which is built in in it.

Model 320d: The oil tank cover (an arrow on an illustration) is before the index of level of oil, at a look in the direction of the movement.

Petrol models: The tank is in the area between the engine and a radiator.


3 Park the car on the flat platform and cock the parking brake.

4 On the cold engine the level of liquid has to be about MIN tag. A liquid level tolerance on the probe from a tag of MIN of ±2 mm.


5 Start the engine and warm up it up to the normal temperature. With the engine idling turn a steering wheel from an emphasis against the stop several times to remove air from system of steering. Switch off the engine, uncover the tank, having turned it counterclockwise, wipe the measuring probe dry and close a cover. Again open a cover and check liquid level. It has to be between two tags.
6 Add liquid small doses until it reaches the necessary level.

Do not allow a liquid modulation. If all this happened, remove surplus with the pure syringe. Close a cover.


7 If the frequent dolivaniye of liquid is required, check hoses and nipple connections of system of hydrostrengthening of a wheel for existence of signs of wear and leaks (address the Section Check of a State and Replacement of Hoses of a Motive Compartment).
8 Check a state and a tension of a driving belt (address the Section Check of a Condition of Driving Ridge Belts).
