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 (refer to 9 - ENGINE/AIR INTAKE SYSTEM/AIR CLEANER HOUSING - INSTALLATION). Air Cleaner - Installation
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.
