Repair Procedures: Replacement

WARNING: This page is about a different car, the 2016 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.

Recover the refrigerant with a recovery/recycling/charging station.
CAUTION:
- Do not use the same A/C recovery/charging station as conventional belt-driven compressors.
- Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.
- If PAG oil mixes into the POE oil of the system, dielectric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.
Drain the coolant.
(Refer to Traction Motor System - "COOLANT ")
Disconnect the negative (-) battery terminal.
Remove the reservoir tank.
(Refer to Traction Motor System - "RESERVOIR ")
Separate the refrigerant line (A) after loosening the mounting bolt.
