12. Remove the A/C suction and discharge line assembly from the engine compartment.
13. Install plugs in, or tape over the opened refrigerant line fittings and the condenser and compressor ports.
14. If necessary, remove the A/C pressure transducer from the A/C discharge line See: Heating and Air Conditioning/Refrigerant Pressure Sensor /
Switch/Service and Repair/A/C Pressure Transducer - Removal.
A/C Suction Line - Installation
INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: Heating and Air Conditioning/Service
and Repair/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 systemSee: Heating and Air Conditioning/Service and Repair/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.
NOTE: The A/C suction line for 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) See: Heating and Air
Conditioning/Refrigerant Pressure Sensor / Switch/Service and Repair/A/C Pressure Transducer - Installation.
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.
