A/C Discharge Line - Installation

INSTALLATION

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system 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 system 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.





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 Nm (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 Nm (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 a variable displacement compressor. Failure to follow these instructions will result in serious A/C compressor damage.

8. Evacuate the refrigerant system Refrigerant System Evacuate.
9. Adjust the refrigerant oil level Refrigerant Oil Level.
10. Charge the refrigerant system Refrigerant System Charge.
