A/C Suction Line - Installation

3.7L ENGINE

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system 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.

NOTE: 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 systemRefrigerant 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.





1. Remove the tape or plugs from the opened refrigerant line fittings and the compressor and expansion valve ports.
2. Lubricate new O-ring seals with clean refrigerant oil and install them and a new gasket on 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.
3. Connect the A/C liquid line (4) to the A/C suction line (1).
4. Connect the A/C liquid and suction lines to the A/C expansion valve (3) and install the retaining nut (2). Tighten the nut to 23 Nm (17 ft. lbs.).





5. Connect the A/C suction line (1) to the A/C compressor (4).
6. Install the nut (2) that secures the A/C suction line to the A/C compressor. Tighten the nut to 12 Nm (105 in. lbs.).
7. Install the air cleaner housing.
8. Reconnect the negative battery cable.
9. Evacuate the refrigerant systemRefrigerant System Evacuate.
10. Adjust the refrigerant oil levelRefrigerant Oil Level.
11. Charge the refrigerant system Refrigerant System Charge.
