INSTALLATION
2.8L DIESEL ENGINE
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - 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 system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT OIL LEVEL).
NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals could result in a refrigerant system leak.
NOTE: RHD model shown in illustrations. LHD model similar.
1. Position the A/C discharge line (5) into the engine compartment.
2. Remove the tape or plugs from the discharge line fitting and compressor port.
3. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it on the discharge line fitting. Use only the specified O-ring 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 discharge line to the A/C compressor (4) and install the retaining bolt (2). Tighten the bolt to 12 N·m (106 ft. lbs.).
5. If removed, install the A/C high pressure switch (3) onto the A/C discharge line. Hand-tightened the switch securely.
6. Connect the engine wire harness (1) to the A/C high pressure switch.
7. Install the front skid plate (refer to 13 - FRAME & BUMPERS/FRAME/FRONT SKID PLATE - INSTALLATION).
8. Lower the vehicle.
9. Engage the A/C discharge line (1) into the retaining clip (2).
10. Remove the tape or plugs from the discharge line fitting and condenser port.
11. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it on the discharge line fitting. Use only the specified O-ring 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.
12. Connect the A/C discharge line to the A/C condenser (3).
13. Install the nut (4) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 22.5 N·m (200 in. lbs.).
14. Reconnect the negative battery cable.
15. Evacuate the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE).
16. Adjust the refrigerant oil level (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT OIL LEVEL).
17. Charge the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM CHARGE).

1. Position the A/C discharge line (4) into the engine compartment.
2. Remove the tape or plugs from the discharge line fittings and the compressor and condenser ports.
3. Lubricate a new rubber O-ring seals with clean refrigerant oil and install them on the discharge 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.
4. Connect the A/C discharge line to the A/C compressor (7) and install the retaining nut (1). Tighten the nut to 27 N·m (20 ft. lbs.).
5. Connect the A/C discharge line to the A/C condenser (6) and install the retaining nut (5). Tighten the nut to 22.5 N·m (200 in. lbs.).
6. If removed, install the A/C pressure transducer (2) onto the A/C discharge line. Hand-tightened the transducer securely.
7. Connect the wire harness connector (3) to the A/C pressure transducer.
8. Reconnect the negative battery cable.
9. Evacuate the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM EVACUATE).
10. Adjust the refrigerant oil level (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING/REFRIGERANT OIL - STANDARD PROCEDURE - REFRIGERANT OIL LEVEL).
11. Charge the refrigerant system (refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM CHARGE).
