A/C Discharge Line - Installation

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, 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 seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber and metal seals could result in a refrigerant system leak.

NOTE: 5.7L model shown in illustrations. 3.6L model similar.





1. Position the A/C discharge line (3) into the engine compartment.
2. Remove the tape or plugs from the opened refrigerant line fittings and the compressor and condenser ports.
3. Lubricate new seals with clean refrigerant oil and install them onto the refrigerant line fittings. Use only the specified seals 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.
5. Install the nut (2) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 20 Nm (15 ft. lbs.).





6. Engage the A/C liquid line (5) to the A/C discharge line (4) and connect the lines to the A/C condenser (1).
7. Install the nut (6) that secures the A/C discharge and liquid lines to the A/C condenser. Tighten the nut to 20 Nm (15 ft. lbs.).
8. Install the bolt (2) that secures the A/C liquid line to the upper radiator support. Tighten the bolt securely.
9. If removed, install the A/C pressure transducer (3) onto the A/C discharge line. Tighten the A/C pressure transducer to 5.1 Nm (45 in. lbs.).
10. Connect the engine wire harness to the A/C pressure transducer.
11. Install the grille Grille - Installation.
12. Install the air cleaner housing, air intake tube and resonator, as equipped.
13. Install the engine trim cover, if equipped.
14. Reconnect the negative battery cable.
15. Evacuate the refrigerant system Refrigerant System Evacuate.
16. Adjust the refrigerant oil level Refrigerant Oil Level.
17. Charge the refrigerant system Refrigerant System Charge.
