  5. Take off a belt of the drive of auxiliary units (see the Head Dvigatel).
  6. Disunite the socket (A9x1) of an electrical wiring of the К/В compressor.
  7. Turn out screws (2) and remove entrance (4) and pressure head (3) lines of a refrigerator path, - at once muffle the open ends of lines and connecting unions in order to avoid hit to the highway of moisture, prepare replaceable sealing rings (5).
  8. Turn out fixing screws (1) and remove assembly of the compressor (A9) of the К/В system.
  9. Remove assembly of a receiver dehumidifier (see the Section Removal and installation of a receiver dehumidifier), - the receiver is subject to replacement without fail. Do not forget to cork the open ends of refrigerator lines.
  10. Installation is made upside-down

Fixing screws (1) have to be filled on the places before installation of the compressor.

  1. Track that to system it was added necessary (on number of the replaced components, - see Specifications) amount of refrigerator oil. Do not forget to oil before installation new sealing rings compressor.
  2. Start the engine and let's it work on single turns within about 4 minutes with the conditioner which is switched on on the maximum refrigerating capacity, - air temperature, given to salon via deflectors of the central air ducts on the dashboard should not fall below value of +5 °C.
  3. Make sure of lack of signs of development of leaks from a refrigerator path.
