3.7L ENGINE

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

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: LHD model shown. RHD model similar.

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 Nm (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 Nm (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.

10. Adjust the refrigerant oil level.

11. Charge the refrigerant system.
