A/C Discharge 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 REFRIGERANT OIL CAPACITIES  to determine how much oil should be added to the refrigerant system .

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.

  1. Position the A/C discharge line into the engine compartment.
