Check and replacement of the compressor and magnetic муфты К/В

Check

 PERFORMANCE ORDER

  1. Start the engine and make sure of absence of a metal sound from the compressor at inclusion К/В. If necessary replace compressor assemblage. If abnormal noise is audible at deenergizing К/В, replace magnetic муфту.
  2. Having the necessary equipment and skills, check up pressure of a coolant and compare it to requirements of Specifications of the Head of System of cooling of the engine, heating, ventilation and an air conditioning.
  1. Separate a socket of the gauge of blocking of the compressor, measure resistance between its contacts 1 and 2 and compare the received result to requirements of Specifications of the Head of System of cooling of the engine, heating, ventilation and an air conditioning. If necessary replace compressor assemblage. Connect a negative wire from the battery to the gauge case, and positive – to contact 3, – thus it should be activated magnetic муфта. Otherwise replace муфту.
  1. Make sure of absence of leaks of a coolant through a control epiploon. If necessary replace the compressor in gathering.
  2. Visually check up tightness of the bearing муфты. Make sure of absence of traces of oil on a press plate.
