A/C Compressor - Installation






COMPRESSOR, A/C

CAUTION: Be certain to adjust the refrigerant system oil level when replacing an A/C compressor Refrigerant Oil Level . Failure to properly adjust the refrigerant oil level can 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 Front A/C Receiver Drier - Removal . 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, see 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 disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

NOTE: 3.6L with 10SRE18 compressor shown in illustrations. Other models similar.





1. If the A/C compressor (2) is being replaced, refrigerant oil must first be drained from the new A/C compressor. When replacing multiple A/C system components, see 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 into the engine compartment.

NOTE: The A/C compressor for 2.0L diesel models uses three bolts to secure the A/C compressor to the engine.

3. Install and hand tighten all the bolts (1 and 3) that secure the A/C compressor to the engine. Then tighten the bolts to 25 Nm (18 ft. lbs.).





4. Remove the tape or plugs from the compressor ports and the refrigerant line fittings.
5. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refrigerant line fittings. Use only the specified O-rings 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 (3) and the A/C discharge line (5) to the A/C compressor (1).

NOTE: The A/C compressor for 2.0L diesel models has one common stud and nut retaining both A/C lines to the compressor.

7. Install the nut or nuts (2 and 4), depending on engine application, that secure the A/C suction and discharge lines to the A/C compressor. Tighten the nut(s) to 20 Nm (15 ft. lbs.).
8. Connect the wire harness to the A/C clutch coil or compressor control valve, depending on engine application.
9. On diesel models install the charge air cooler inlet hose .
10. Install the accessory drive belt Serpentine Accessory Drive Belt - Installation.
11. Install the splash shields located under the engine and front fascia Front Lower Fascia Closeout - Installation.
12. Install the right front inner wheelhouse splash shield Splash Shield - Installation
13. Lower the vehicle.
14. Reconnect the negative battery cable.

CAUTION: Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C system when equipped with a variable displacement compressor. Failure to follow these instructions will result in serious A/C compressor damage.

15. Evacuate and charge the refrigerant system Refrigerant System Charge.
