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.
12. Connect the A/C discharge line (2) to the A/C compressor (3).
13. Install the nut (1) that secures the A/C discharge line to the A/C compressor. Tighten the nut to 20 Nm (15 ft. lbs.).

INSTALLATION
CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system See: 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.
CAUTION: The A/C liquid line must be replaced if an internal failure of the A/C compressor has occurred. Failure to replace the A/C liquid
line can 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: 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.
