A/C Compressor - Installation
3.0L ENGINE
CAUTION: If the A/C compressor is being replaced, be certain to adjust the refrigerant system oil level Refrigerant Oil Level. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.
CAUTION: The A/C receiver/drier must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C receiver/drier can cause serious damage to the replacement A/C compressor.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be removed from the new A/C compressor Refrigerant Oil Level.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

1. If the A/C compressor (4) is being replaced, the refrigerant oil in the old compressor must be first drained and measured. Then the oil in the new A/C compressor must be drained. Finally, the new compressor must be refilled with the same amount of new refrigerant oil that was drained out of the old compressor Refrigerant Oil Level. When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system Refrigerant Oil Level. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
2. Position the A/C compressor to the engine and install the three bolts (2 and 3) that secure the compressor to the engine. Tighten the bolts to 55 Nm (41 ft. lbs.).
3. Connect the wire harness connector (2) to the A/C compressor.
4. Remove the tape or plugs from the opened refrigerant line fittings and the compressor ports.
5. Lubricate new dual-plane seals with clean refrigerant oil and install them onto the refrigerant line fittings. Use only the specified seals as they are made of a special material for the R-134a system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
6. Connect the A/C suction line (1) and the A/C discharge line (2) to the A/C compressor (4).
7. Install the nuts (5 and 6) that secure the refrigerant lines to the A/C compressor. Tighten the nuts to 20 Nm (15 ft. lbs.).
8. Install the accessory drive belt (3) Accessory Drive Belt - Installation.
9. Install the belly pans.
10. Lower the vehicle.
11. Replace the A/C receiver/drier if the A/C compressor is being replaced due to an internal failure Removal and Installation.
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system Refrigerant System Evacuate.
14. Charge the refrigerant system Refrigerant System Charge.
15. Install the beauty cover onto the top of the engine.
