A/C Liquid Line - Installation

INSTALLATION

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 opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.





1. Position the A/C liquid line (1) into the engine compartment.
2. Remove the tape or plugs from the opened liquid and suction line fittings and the receiver/drier and expansion valve ports.
3. Lubricate a new O-ring seal with clean refrigerant oil and install it onto the rear liquid line fitting. Use only the specified O-ring seal as it is 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.
4. Connect the A/C liquid line to the A/C expansion valve (2) and engage the two liquid line retainer clips (4) to the frame rail (3).





5. Lubricate a new dual-plane seal with clean refrigerant oil and install it onto the front liquid line fitting. Use only the specified seal as it is 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 liquid line (2) to the A/C receiver/drier (3).
7. Install the nut (1) that secures the A/C liquid line to the A/C receiver/drier. Tighten the nut to 20 Nm (15 ft. lbs.).






NOTE: LHD model with 5.7L engine shown. RHD model and other engines similar.

8. Lubricate a new O-ring seal with clean refrigerant oil and install it onto the rear suction line fitting. Use only the specified O-ring seal as it is 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 A/C suction line (2) to the A/C expansion valve (1).
10. Install the nut (3) that secures the A/C suction line and the A/C liquid line (10) to the A/C expansion valve. Tighten the nut to 20 Nm (15 ft. lbs.).
11. Install the air cleaner housing, air intake tube and the resonator (if equipped) Air Cleaner Body - Installation.
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system Refrigerant System Evacuate.
14. Adjust the refrigerant oil level Refrigerant Oil Level.
15. Charge the refrigerant system Refrigerant System Charge.
