5.2.8. Check of level of coolant in a working path of the K/V system

Observe all necessary precautionary measures connected with service of the K/V systems (see the Section the General information and security measures)!

Location of an observation port of a receiver dehumidifier in a motive compartment of models of release on 12.2000 g.

 PERFORMANCE ORDER

  1. If the receiver dehumidifier To/in is located ahead of a radiator, remove a forward decorative lattice (see the Head Kuzov).
  2. Wipe glass of an observation port (shooter) on assembly of a receiver dehumidifier.
  3. Disunite the socket (2) of the low pressure sensor switch and you peremknit plugs of the last.
  4. Start the engine on single turns.
  5. Turn on the fan of a heater and activate the K/V system in the mode of the maximum refrigerating capacity.
  6. Remove a crossing point from the socket of the sensor switch of pressure and, having glanced in an observation port of a receiver dehumidifier, make sure of lack of signs of a puzyreniye of coolant (at primary start of svezhezapravlenny system formation of air bubbles should not cause concerns, - wait about 10 minutes, - bubbles have to disappear, the insignificant puzyreniye is also admissible at high [> 35 °C] ambient temperatures)

At operation of an electromagnetic clutch coupling of the compressor the speed of a stream of liquid has to increase.

  1. Attentively study an external condition of all components refrigerator To/in, by means of the special detector check them for existence of signs of development of leaks.
  2. Transfer the fan to the high-speed 1 mode and by means of the special measuring instrument measure temperature of the air which is coming out via the central deflectors of the dashboard. 5 minutes of functioning of system later temperature of the air given to salon has to be in limits of the range of +2 °C of ÷ of +12 °C, and the K/V compressor has to pass into the cyclic mode (vkl-vykl), otherwise it is necessary to check a condition of the sensor switch of temperature of the evaporator.
  3. Switch off the conditioner and kill the engine, - more detailed checks of the K/V system have to be carried out in the conditions of a workshop of car service.
