2.7L ENGINE

CAUTION: If the A/C compressor is being replaced, be certain to adjust the refrigerant system 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.

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 (5) 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. 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. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

CAUTION: Use care not to deform or damage the automatic transmission cooler lines and retaining bracket when repositioning the A/C compressor.

NOTE: The bolt that secures the transmission cooler line bracket to the A/C compressor must be installed through the bracket and the lower front mounting hole of the compressor prior to final positioning of the compressor to the cylinder block.

2. Loosely install the bolt (3) that secures the automatic transmission cooler line bracket (4) to the A/C compressor and position the compressor, bracket and bolt to the cylinder block (6).

3. Loosely install the bolts (1 and 2) that secure the A/C compressor to the cylinder block.

4. Tighten the three bolts in the following order:
- Upper front bolt to 26 Nm (19 ft. lbs.).
- Lower front bolt to 26 Nm (19 ft. lbs.).
- Rear bolt to 50 Nm (37 ft. lbs.).

5. Install the front belly pan.

6. Lower the vehicle.





7. Remove the tape or plugs from the opened fittings on the A/C suction line (3) and the A/C discharge line (4) and the compressor ports.

8. Lubricate the new dual plane seals with clean refrigerant oil and install them onto the suction and the discharge 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.

9. Connect the suction and discharge lines onto the A/C compressor (5).

10. Install the nuts (2) that secure the suction and discharge lines to the A/C compressor. Tighten the nuts to 23 Nm (17 ft. lbs.).

11. Connect the engine wire harness to the compressor clutch field coil connector (1).

12. Install the accessory drive belt.

13. Replace the A/C receiver/drier if the A/C compressor is being replaced due to an internal failure.

14. Install the air cleaner housing.

15. Reconnect the negative battery cable.

16. Evacuate the refrigerant system.

17. Charge the refrigerant system.
