1. Recover the refrigerant from the refrigerant system.
2. Disconnect and isolate the negative battery cable.
3. Remove the air cleaner housing, air intake tube and the resonator.
4. Remove the nut (3) that secures the A/C suction line (2) and the A/C liquid line (10) to the A/C expansion valve (1).
5. Disconnect the A/C suction line from the A/C expansion valve and remove and discard the O-ring seal.
6. Remove the nut (1) that secures the A/C liquid line (2) to the receiver/drier (3).
7. Disconnect the A/C liquid line from the receiver/ drier and remove and discard the dual plane seal.
8. Disengage the two liquid line retainer clips (4) from the right frame rail (3). If required remove the clips from the liquid line
9. Disconnect the A/C liquid line (1) from the A/C expansion valve (2) and remove and discard the O-ring seal.
10. Install plugs in, or tape over the opened liquid and suction line fittings and the receiver/drier and expansion valve ports.
11. Remove the A/C liquid line from the engine compartment.
INSTALLATION
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 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 receiver/drier (3).
7. Install the nut (1) that secures the A/C liquid line to the receiver/drier. Tighten the nut to 20 N.m (15 ft. lbs.).
NOTE: LHD model with 5.7L engine shown in illustration. RHD model and other engines similar.

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 23 N.m (17 ft. lbs.).
11. Install the air cleaner housing, air intake tube and the resonator.
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system.
14. Charge the refrigerant system.
