Removal and installation of the compressor

You will need: keys "for 10", "for 13".

1. Remove the refrigerant from the air conditioning system (see Removing Refrigerant from the Air Conditioning System). Install the car on a viewing ditch.

Disconnect the wire from the negative terminal of the battery.



2. Remove the engine mudguard (see Removal and installation of mudguard and crankcase protection).

3. Remove the accessory drive belt (refer to Inspection and Replacement of the Accessory Drive Belt).



4. Check the condition of the drive belt.

USEFUL ADVICE: Replace the belt if during inspection you find: – signs of wear on the toothed surface, cracks, undercuts, folds and delamination of the fabric from the rubber; – cracks, folds, depressions or bulges on the outer surface of the belt; – loosening or delamination on the end surfaces of the belt; – Traces of oil on any surface of the belt.

WARNING: A belt with traces of engine oil on any surface must be changed without fail, as the oil quickly destroys the rubber. Cause of oil on the belt (usually due to leakage of the engine shaft seals) must be eliminated immediately.

5. Squeeze the latch and disconnect the wiring harness block from the compressor electromagnetic clutch.

6. Turn away a fastening nut and disconnect flanges of pipelines of low and high pressure from the compressor.

7. Turn out bolts of fastening of the compressor, take bolts from assembly apertures and remove the conditioner compressor.

WARNING: Immediately after disconnecting, plug the compressor and A/C piping to prevent moisture and dirt from entering the A/C system.

8. Install the compressor and all removed parts in the reverse order of removal.

WARNING: Do not open the process flange plugs of a new compressor until just before connecting the piping.

When installing new pipe block flange O-rings, be sure to lubricate them with A/C compressor oil.

9. Charge the air conditioning system with refrigerant at a specialized auto air conditioning service center.

USEFUL ADVICE: When buying a new compressor, check with the seller the amount and type of oil poured into the new compressor. This information may be useful to mechanics who later charge the system with refrigerant.
