INSTALLATION 

3.7L ENGINE 

CAUTION: If the A/C compressor is being replaced, be certain to adjust the refrigerant 

system oil level. See 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 receiver/drier must be replaced if an internal failure of the A/C 

compressor has occurred. Failure to replace the A/C receiver/drier 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. See 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.
