Discharge Line

INSTALLATION

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, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant systemRefrigerant Oil Level

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.





NOTE: A/C compressor for 4.0L engine shown. 3.8L engine A/C compressor similar.

1. Position the A/C discharge line (3) into the engine compartment.
2. Remove the tape or plugs from the discharge line fittings and the condenser and compressor ports.
3. 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.
4. Connect the A/C discharge line to the A/C compressor (2).
5. Install the nut (1) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 23 Nm (17 ft. lbs.).




6. Connect the A/C discharge line (2) to the A/C condenser (3).
7. Install the nut (1) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 23 Nm (17 ft. lbs.).




8. Position the radiator end air seal (2) to the right side of the A/C condenser (3) and install the retaining pins (1).
9. Install the front fascia.
10. Install the radiator closure panel 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.
