If in a receiver the lowered level of liquid is found, it is necessary to check all system of the steering mechanism as soon as possible. Otherwise the amplifier of the steering mechanism can suddenly stop work during movement. The sequence of check below is given:


  1. To turn out a steering wheel once to the right and once on the left against the stop. Thus in the power steering the highest possible pressure is formed, and not tight places become more appreciable.
  2. To leave a steering wheel in one of extreme provisions and to check the following places on a leakage:
  3. Rotor valve. It is located approximately where the steering column incorporates to the steering mechanism. Working liquid in this case acts in car salon under a control panel on a forward wall.
  4. Podtekaniye on sealing laying of a gear lath or sealing laying in the left tip. For check to weaken clips of a casing and to shift it aside.
  5. On the hydraulic pump. For leakage identification, probably, before check it is necessary to wash the engine.
