Installation
5.9L/6.7L DIESEL ENGINES
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.
NOTE: The A/C suction line for the 5.9L and the 6.7L diesel engine is serviced as an assembly with the A/C discharge line.
1. If removed, install the A/C pressure transducer (4) onto the A/C suction and discharge line assembly (3).
2. Remove the tape or plugs from the opened refrigerant line fittings and the condenser and compressor ports.
3. Position the A/C suction and discharge line assembly into the engine compartment.
4. Lubricate new O-ring seals with clean refrigerant oil and install them and new gaskets onto the refrigerant line fittings. Use only the specified
O-ring 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.
5. Connect the A/C suction and discharge line assembly to the A/C condenser (1).
6. Install the nut (2) that secures the A/C suction and discharge line assembly to the A/C condenser. Tighten the nut to 23 Nm (17 ft. lbs.).
7. Connect the A/C suction and discharge line assembly to the A/C compressor (6).
8. Install the bolt (7) that secures the A/C suction and discharge line assembly to the A/C compressor. Tighten the bolt to 23 Nm (17 ft. lbs.).
9. Connect the wire harness connector (5) to the A/C pressure transducer.
