4.0L 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 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. Remove the tape or plugs from the opened discharge line fittings and compressor and condenser ports.

2. Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto 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.

3. For clearance, position the A/C condenser (3) toward the left side of the vehicle.

4. Connect the A/C discharge line (5) to the A/C condenser and install the retaining nut (4) hand tight.

5. Reposition the A/C condenser and install the bolt (2) that secures the condenser to the right side of the radiator (1). Tighten the bolt to 5 Nm (44 in. lbs.).

6. Tighten the nut that secures the A/C discharge line to the A/C condenser to 22.5 Nm (200 in. lbs.).

7. Install the grille.





8. Connect the A/C discharge line (1) to the A/C compressor (4).

9. Install the nut (2) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 12 Nm (105 in. lbs.).

10. Install the air cleaner housing.

11. Reconnect the negative battery cable.

12. Evacuate the refrigerant system.

13. Adjust the refrigerant oil level.

14. Charge the refrigerant system.
