A/C Refrigerant Discharge Line

A/C Refrigerant Discharge Line


Review safety precautions and warnings in this group before performing this procedure. Failure to follow the warnings and cautions may result in serious or fatal injury.

Removing

- Disconnect and isolate the negative battery cable.

- Recover the refrigerant from the refrigerant system. Refer to => [ Refrigerant System, Recovery ] Refrigerant System, Recovery.

- Remove the nut (3) that secures the A/C discharge line (1) to the condenser tapping block (2) located in the right front corner of the engine compartment.

- Disconnect the A/C discharge from the A/C condenser.

• 4.0L engine shown. Other engines similar.

- Remove the nut (2) that secures the A/C discharge line (1) to the A/C compressor (3).

- Disconnect the A/C discharge line from the A/C compressor.

- Remove the A/C discharge line from the engine compartment and remove and discard the O-ring seals and gaskets.

- Install plugs in, or tape over the opened refrigerant line fittings and the condenser and compressor and ports.

Installing


Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Refer to => [ A/C Compressor Refrigerant Oil Charge ] A/C Compressor Refrigerant Oil Charge. 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.

• 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. Refer to => [ A/C Compressor Refrigerant Oil Charge ] A/C Compressor Refrigerant Oil Charge.

• 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 may result in a refrigerant system leak.

• 4.0L engine shown. Other engines similar.








- Position the A/C discharge line (1) into the engine compartment.

- Remove the tape or plugs from the opened refrigerant line fittings and the compressor and condenser ports.

- 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.

- Connect the A/C discharge line to the A/C compressor (3).

- Install the nut (2) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 23 Nm (17 ft lbs).






- Connect the A/C discharge line (1) to the condenser tapping block (2).
