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, refer to 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 opened. Failure to replace the
rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
1. Position the A/C discharge line (2) into the engine compartment.
2. Remove the tape or plugs from the opened discharge line fittings and the condenser and compressor ports
3. 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-ring as it is 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.
4. Install the A/C discharge line to the A/C compressor.
5. Install the nut (1) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 23 Nm (17 ft. lbs.).
6. Install the A/C discharge line to the A/C condenser (4).
7. Install the nut (3) that secures the A/C discharge line to the A/C condenser. Tighten the nut to 23 Nm (17 ft. lbs.).
8. Reconnect the negative battery cable.
9. Evacuate the refrigerant system See: Heating and Air Conditioning/Service and Repair/Refrigerant System Evacuate.
10. Adjust the refrigerant oil level See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Level.
11. Charge the refrigerant systemSee: Heating and Air Conditioning/Service and Repair/Refrigerant System Charge.
