2. Disconnect the wire from the terminal «minus» battery.
3. Remove the right engine splash guard (see «Removing and installing mudguards and engine crankcase protection»).
4. Remove the accessory drive belt (see «Replacement of auxiliary drive belts»).
5. Check the condition of the drive belt.
Note: Replace the belt if upon inspection you find:
- signs of wear on the toothed surface, cracks, cuts, folds or separation of the fabric from the rubber;
- cracks, folds, indentations or bulges on the outer surface of the belt;
- fraying or delamination on the end surfaces of the belt;
- traces of oil on the surface of the belt.
Warning: A belt with traces of motor oil on any of its surfaces must be replaced, as oil quickly destroys rubber. The reason for oil getting on the belt (usually due to a leak in the engine shaft seals) must be eliminated immediately.
6. Unscrew the bolts securing the flanges of the low A and high B pressure pipelines to the compressor body and disconnect the pipelines.
Warning: Immediately after disconnecting, plug the compressor and pipe openings to prevent moisture and dirt from entering the air conditioning system.
7. Disconnect the wiring harness connector of the electromagnetic clutch of the compressor.
8. Remove the four mounting bolts...
9.... remove them from the mounting holes and remove the air conditioning compressor by lowering it down.
10. Install the compressor and all removed parts in the reverse order of removal. Tighten the compressor mounting bolts to 25 N·m.
Warning: Open the new compressor flange access plugs only immediately before connecting the pipes. When installing new pipe flange sealing rings, be sure to lubricate them with air conditioning compressor oil.
11. Make sure that when installing the drive belt, the V-grooves coincide with the pulley grooves...
12....and the belt tension is within the norm.
13. Fill the air conditioning system with refrigerant at a specialized car air conditioning service center.
Helpful Hint: When purchasing a new compressor, ask the seller about the amount and type of oil that is filled into the new compressor. This information may also be useful for mechanics who will subsequently fill the system with refrigerant.
