1. Position the discharge line into the engine compartment.
2. If equipped with the 3.5L/3.8L diesel engine, install the discharge line to the retaining clip located on the left side of the engine.
3. Remove the tape or plugs from the condenser inlet port and the discharge line fitting.
4. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it on the discharge line fitting. Use only refrigerant oil of the type recommended for the compressor in the vehicle.
5. Connect the discharge line fitting to the condenser inlet port.
6. Install the nut that secures the discharge line fitting to the condenser tapping block. Tighten the nut to 12 Nm (105 in. lbs.).
7. Remove the tape or plugs from the compressor discharge port and the discharge line fitting.
8. Lubricate a new rubber O-ring seal with clean refrigerant oil and install it on the discharge line fitting. Use only refrigerant oil of the type recommended for the compressor in the vehicle.
9. Connect the discharge line fitting to the compressor discharge port on the top of the compressor.
10. Install the bolt or nut (depending on engine application) that secures the discharge line fitting to the compressor. Tighten the bolt or nut to 28 Nm (20 ft. lbs.).
11. Connect the wire harness connector to the A/C pressure transducer or A/C high pressure switch (depending on engine application).
12. Reconnect the negative battery cable.
13. Evacuate the refrigerant system.
