GENERAL INFORMATION

Elements of central air of air

1. The switch of the cooling fan of a radiator of N2 (the 6-cylinder engine)
2. N1 relay block
Coupling relay (MG CLT marking)
Heater relay (HTR marking)
The relay of the second cooling fan (FAN NO.2 marking)
The relay of the third cooling fan (FAN NO.3 marking)
3. N2 relay block
Main relay of the engine (ENGINE MAIN marking)
The relay of the first cooling fan (FAN NO.1 marking)

4. Refrigerator
5. The switch of the cooling fan (the 4-cylinder engine)
6. Store
7. Pressure sensor
8. Refrigerator fan
9. Compressor
10 Switch of the cooling fan of a radiator of N1 (the 6-cylinder engine)

Within maintenance it is necessary to carry out the following checks regularly:

  – check a condition of a driving belt of the compressor. If necessary replace a belt;
  – check a tension of a belt and if necessary adjust it;
  – examine system hoses on existence of cracks, swellings, and the ground places. If necessary replace hoses;
  – examine edges of the refrigerator and clean the dirt which has got stuck in them;
  – check, pressure of a coolant.

Check

PERFORMANCE ORDER
1. Warm up the engine to working temperature.
2. Establish the handle of adjustment of temperature in the provision of cold air. Include the maximum speed of the delivery fan.
3. After central air will reach working temperature, touch two tubes connected to the refrigerator.
4. Thinner tube should be cold, and thicker tube should be even colder (about-16 ° With or–12 ° C).
If the thick tube is much warmer, than thin, the system should be charged in addition a coolant. Insert the thermometer into the center of a ventilating opening. The air temperature, arriving of an opening should be lower on 3–5 ° With, than air temperature. If not so, system it is necessary to charge it in addition a coolant, for this purpose address to the expert.

COOLANT

Set for additional charge of R-134a systems


For additional charge of central air of air by a coolant, coolant R-134a is used. Any motorist can independently carry out central air additional charge. For this purpose it is necessary to get a special set for additional charge with the appendix of instructions on its use.

PERFORMANCE ORDER
1. Connect a hose to the valve located on a tube of a coolant (it is specified by an arrow).
2. Close contacts 1 and 4 sensors of pressure of central air by means of a crossing point (it is specified by an arrow) that the compressor continued to work when you charge system a coolant.

CENTRAL AIR SMELLS

For removal of the smells arising in central air of air, usually use special disinfectants. And, though, the best decision would be to address in a specialized workshop, you can process central air elements.

PERFORMANCE ORDER
Remove the resistor of the delivery fan and process disinfectant structure the evaporator.
