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 system See: Heating and Air Conditioning/Service and Repair/Refrigerant Oil Level.
NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line is disconnected. Failure to replace the rubber
O-ring seals may 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 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 (8) into the engine compartment.
4. Connect the A/C discharge line onto the A/C compressor (9).
5. Install the bolt that secures the A/C discharge line to the A/C compressor. Tighten the bolt to 22 Nm (16 ft. lbs.).
6. Connect the A/C discharge line onto the A/C condenser (7).
7. Install the nut that secures the A/C discharge line to the A/C condenser. Tighten the nut to 6 Nm (53 in. 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.
12. Install the air cleaner housing See: Filters/Air Cleaner Housing/Service and Repair.
