Dodge Journey: Line, A/C discharge

DESCRIPTION

Heating & Air Conditioning
Fig. 241: Discharge Line Description

NOTE: 2.7L shown. Other engines similar.

The A/C discharge line (2) is the refrigerant line that carries refrigerant from the A/C compressor to the A/C condenser.

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.

The A/C discharge line has no serviceable parts except for the metal gaskets (1) and rubber O-ring seals (3) used on the fittings. The O-ring seals are made from a special type of rubber not affected by R-134a refrigerant.

The O-ring seals and gaskets must be replaced whenever the A/C discharge line is disconnected.

The A/C discharge line cannot be repaired and must be replaced if leaking or damaged.

REMOVAL

WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation. Failure to follow the warnings and cautions may result in possible serious or fatal injury.

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

6. Disconnect the A/C discharge line from the A/C compressor and remove the discharge line from the engine compartment.

7. Remove and discard the O-ring seals and gaskets and install plugs in, or tape over the opened discharge line fittings and the compressor and condenser ports.

INSTALLATION

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 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 disconnected. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.

NOTE: 2.7L shown. Other engines similar.

1. Remove the tape or plugs from the opened discharge line fittings and the compressor and condenser ports.

2. 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.

3. Position the A/C discharge line (1) into the engine compartment and connect it to the A/C compressor (2).

4. Install the nut (3) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 20 N.m (15 ft. lbs.).

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

6. Install the nut (5) that secures the A/C discharge line to the tapping block. Tighten the nut to 20 N.m (15 ft. lbs.).

7. Reconnect the negative battery cable.

CAUTION: Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/C system when equipped with the Denso 6SEU16 variable displacement compressor. Failure to follow this caution will result in serious A/C compressor damage.

8. Evacuate the refrigerant system.

9. Adjust the refrigerant oil level.

10. Charge the refrigerant system.
