Check

PERFORMANCE ORDER
1. Raise and establish a forward part of the car on reliable support.
2. Remove the left forward wheel.
3. Remove локарь niches of a forward left wheel.
4. Launch the engine.
5. Check for hearing and to the touch operation of the pump unit 1 (see rice. Elements of the hydraulic amplifier of steering). If necessary turn a steering wheel against the stop.
6. If the pump unit does not work, check electric chains (see subsection 8.5.6).
7. More careful inspection of the pump can be carried out at service station by means of special devices.
8. Replace the failed pump unit.
9. Establish into place локарь and a wheel.

Replacement

PERFORMANCE ORDER
1. Disconnect a wire from the - plug of the rechargeable battery. On a part of cars the holder of the rechargeable battery (the bigger size) closes a receiver cover. In this case it is necessary to remove the rechargeable battery and its holder (see subsection 10.2).
2. If necessary remove the air filter (see subsection 4.1).
3. Turn off a cover 9 (see rice. Elements of the hydraulic amplifier of steering) a receiver and through a bulk mouth by means of a rubber pear remove working liquid from a receiver.
4. Raise and establish a forward part of the car on reliable support.
5. Remove the left forward wheel.
6. Remove локарь niches of a forward left wheel.
7. Remove an antisplash guard.
8. On models with the control unit of the fan of the conditioner disconnect from the block two blocks 4 and 5 (see rice. An arrangement of the control unit of the conditioner fan) with wires, turn off two nuts 3 fastenings and remove an arm 2 with the block 1.
9. Wring out a spring latch and open the holder 1 (see rice. Extraction of a wire and highways from the holder). Take out from it pressure head 3 and returnable 2 highways, and also a wire 4 sensors of the amplifier of steering.
10. Establish under the pump unit capacity for collecting liquid which will follow from it at removal.
11. Disconnect from the pump unit of 1 block 2 (see rice. Connecting blocks of the pump unit), 3 and 4 with wires.
12. Unclench by means of flat-nose pliers a collar 5 (see rice. Connection of highways to the pump unit) and accurately disconnect the returnable highway 4 from the union of the pump unit.
13. Turn off a nut 2 fastenings and disconnect the pressure head highway 3 from the pump unit.
14. Muffle openings of highways.
15. Turn off three bolts 3 (see rice. Fastening of the pump unit on the car) fastenings also remove an arm 2 with the pump unit 1 in an elastic casing.
16. Turn off three nuts 1 (see rice. The pump unit with an arm assembled) fastenings also remove from an arm the 3rd pump unit 2 in an elastic casing 4.
17. Undo an elastic casing 10 (see rice. Details of the pump unit) also take out from it the pump unit 4.
18. Turn out three rubber support 3. Replace support with the rubber torn, exfoliated or lost elasticity.
19. Install the new pump unit upside-down, having replaced bolts of fastening of an arm of the pump unit new.
20. Replace a sealing ring of the 7th tip of the pressure head highway.
21. After that fill hydraulic system with working liquid and remove from it air (see subsection 8.5.10).
