Removal
Warning: The air conditioning system is under high pressure. Do not loosen couplings or remove components without first discharging the system when contacting a branded or specialized service station. Disconnecting the air conditioning system couplings should be done while wearing safety glasses or a mask.
Note: If the compressor is replaced, the battery/drier must also be replaced (see subsection 14) and expansion tube (see subsection 18).
1. Discharge the air conditioning system at an appropriate service station (see warning above).
2. Disconnect the negative battery cable.
3. Clean the areas of the compressor adjacent to the refrigerant line couplings.
4. Remove the drive belt (see chapter 1).
5. Remove the generator (see chapter 5) and the drive belt idler pulley bracket.
6. Disconnect the connector (s) compressor wiring (see illustration).
15.6. Location of compressor mounting bolts: A - connecting nut of the refrigerant circulation line; B - Refrigerant pressure sensor; C - Compressor mounting bolts (the top bolt is shown - the bottom fastener is invisible from this angle); D - Compressor drive clutch connector; E - Drive belt intermediate pulley bracket
7. Disconnect the suction and discharge unit from the compressor. Both lines are connected to the compressor by a twin coupling, which is secured with a single bolt. Plug connectors to prevent clogging and moisture from entering the system. The seals located between the plate and the compressor must be replaced.
8. Unscrew the mounting bolts and remove the compressor.
Installation
9. If replacement is planned, drain the oil from the new compressor into a graduated container to determine the volume that needs to be added to the new compressor. The requirements of the accompanying instructions must be observed.
Note: Sometimes the replacement compressor is supplied with oil filled. Follow the directions in the accompanying instructions for draining excess oil before installation.
Caution: The oil added to the system must be R-134a grade refrigerant.
10. Installation is carried out in the reverse order of removal. When installing a connecting unit for refrigerant circulation lines on a compressor, it is necessary to replace the seals and lubricate them with compressor oil, then tighten the fastening nut securely.
11. Connect the negative battery cable.
12. Charge the air conditioning system by contacting a specialized station.
