A/C Liquid Line Installation
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. 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, see the Refrigerant Oil Capacities chart to determine how much oil should be added to the refrigerant system. Refer to STANDARD PROCEDURE .
NOTE:
The Fiat 500e A/C system uses a
UNIQUE POE OIL
in high-voltage compression because it is non-conductive.
NOTE:
Replacement of the refrigerant line seals is required anytime a refrigerant line is disconnected. Failure to replace the seals may result in a refrigerant system leak.
- Position the A/C liquid line into the engine compartment.
- Install the two RH upper core support bolts (1).
