To install:


CAUTION
If the A/C compressor is being replaced, be certain to adjust the refrigerant system 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 accumulator and 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 accumulator and the A/C liquid line can cause serious damage to the replacement A/C compressor.


NOTE
When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be removed from the new A/C compressor.


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. If the A/C compressor (1) is being replaced, 70 milliliters (2.4 oz.) of refrigerant oil must first be drained from the new A/C compressor. 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. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
  2.  
  3. Position the A/C compressor into the engine compartment.
