1. Remove the refrigerant from the air conditioning system (see «Removing refrigerant from the air conditioning system»).
2. Install the car on an inspection ditch.
3. Disconnect the wire from the terminal «minus» battery.
4. Remove the crankcase protection...
5....and the right engine mudguard (see «Removal and installation of mudguards and engine crankcase protection»).
6. Remove the accessory drive belt (see «Replacing accessory drive belts»).
7. Check the condition of the drive belt.
NOTE: Replace the belt if, upon inspection, you find:
- signs of wear on the toothed surface, cracks, undercuts, folds or 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 the 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.
8. Press the latch...
9.... and disconnect the block of the wiring harness from the block of the electromagnetic clutch for turning on the compressor.
10. Turn out a bolt of fastening of a flange of pipelines of low and high pressure to the compressor, take a bolt from a hole...
11.... and disconnect the pipelines from the compressor.
WARNING: Immediately after disconnecting, plug the compressor and A/C piping to prevent moisture and dirt from entering the A/C system.
12. Turn out bolts of fastening of the compressor to an arm on the block of cylinders.
NOTE: This is how the A/C compressor mounting bolts are located.
13. Remove the bolts from the mounting holes and remove the A/C compressor by lowering it down.
14. Install the compressor and all removed parts in the reverse order of removal.
WARNINGS: Do not open the flange access plugs of a new compressor until just before connecting the piping. When installing new pipe flange O-rings, be sure to lubricate them with A/C compressor oil.
15. Make sure that when installing the drive belt, the wedge tracks coincide with the pulley grooves, and the belt tension is correct.
16. Charge the A/C system with refrigerant at a specialized automotive air conditioner 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.
