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 fitting and the inlet port on the A/C condenser (5).
3. Lubricate a new dual plane seal with clean refrigerant oil and install it onto the discharge line fitting. Use only the specified seal 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 onto the A/C condenser.
5. Reach through the headlamp opening in the upper radiator support and install the nut (1) that secures the A/C discharge line to the A/C condenser.
Tighten the nut to 22 Nm (16 ft. lbs.).
