A/C Discharge Line - Installation

4.0L ENGINE

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, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system Refrigerant Oil Level .

NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. 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 Grille - Installation.





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 Air Cleaner Body - Installation.
11. Reconnect the negative battery cable.
12. Evacuate the refrigerant system Refrigerant System Evacuate.
13. Adjust the refrigerant oil level Refrigerant Oil Level.
14. Charge the refrigerant system Refrigerant System Charge.
