Repair Procedures: Replacement

WARNING: This page is about a different car, the 2019 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • Be sure to read and follow the "General Safety Information And Caution " before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
  • Be sure to shut off the high voltage before doing any work related with the high voltage system (Refer to "HIGH VOLTAGE SHUT-OFF PROCEDURE "). Failure to follow the safety instructions may result in serious electrical injuries.
CAUTION:
  • Put on gloves to protect your hands.
NOTE:
  • When prying with a flat-tip screwdriver, wrap it with protective tape, and apply protective tape around the related parts, to prevent damage.
  • Use a plastic panel removal tool to remove interior trim pieces to protect from marring the surface.
  • Take care not to bend or scratch the trim and panels.
  1. 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.
  2. Disconnect the negative (-) battery terminal.
  3. Shut off the high voltage circuit. (Refer to EV Battery System - "HIGH VOLTAGE SHUT-OFF PROCEDURE ")
  4. Remove the cowl top cover.

    (Refer to Body - "COWL TOP COVER ")

  5. Remove the pipe (A) after loosening the mounting bolts.

    Tightening torque: 

    7.8 ~ 11.7 N.m (0.8 ~ 1.2 kgf.m, 5.7 ~ 8.6 lb-ft)

    CAUTION:
    • Plug or cap the lines immediately after disconnecting them to avoid moisture and dust contamination.

    CAUTION:
    • Do not use the same A/C recovery/charging station as conventional belt-driven compressors.
    • If PAG oil mixes into the POE oil of the system, die electric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.
    • 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.
    • If you're installing a new condenser, add refrigerant oil (POE OIL).
    • Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-134a to avoid leakage.
    • Be careful not to damage the radiator and condenser fins when installing the condenser.
    • Be sure to install the lower mount cushions of condenser securely into the holes.
    • Charge the system, and test its performance.
