THE GENERAL DATA

Elements of a central air of air

1. The switch of the cooling fan of radiator N2 (the 6-cylinder engine) 2. Relay N1 block The coupling relay (marks MG CLT) The heater relay (marks HTR) The relay of the second cooling fan (marks FAN NO.2) The relay of the third cooling fan (marks FAN NO.3) 3. Relay N2 block The main relay of the engine (marks ENGINE MAIN) The relay of the first cooling fan (marks FAN NO.1)

4. A refrigerator 5. The switch of the cooling fan (the 4-cylinder engine) 6. The store 7. The pressure gauge 8. The refrigerator fan 9. The compressor 10 Switch of the cooling fan of radiator N1 (the 6-cylinder engine)

Within the limits of maintenance service it is necessary to spend following checks regularly:

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

Check

PERFORMANCE ORDER

1. Warm up the engine to working temperature. 2. Establish the handle of adjustment of temperature in position of cold air. Include the maximum speed of the delivery fan. 3. After the central air will reach working temperature, touch two tubes connected to a refrigerator. 4. More thin tube should be cold, and thicker tube should be even colder (approximately–16 ° With or–12 °). If the thick tube is much warmer, than thin, the system should be charged in addition a coolant. Insert the thermometer into the centre of a ventilating aperture. The temperature of air arriving from an aperture should be more low 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 systems R-134a


For additional charge of a central air of air by a coolant, coolant R-134a is used. Any motorist can spend additional charge of a central air independently. 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 gauges of pressure of a central air by means of a crosspiece (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 a central air of air, usually use special disinfectants. And, though, the best decision would be to address in a specialised workshop, you can process central air elements.

PERFORMANCE ORDER

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