Remove

  1. Drain the coolant from the power conversion system. See Penthouse Coolant (Drain and Refill).
  2. Remove the HV battery negative contactor. See Contactor - Negative - HV Battery (Remove and Replace).
  3. Cut a slit halfway through 2 absorbent pads and surround each coolant output tube fitting with a pad.
  4. Use the coolant connector removal tool to spread the tube fitting clips wider than the barb on the power conversion system.
    Example of Coolant Connector Removal Tool Use
  5. Pull up on the tool and the tube fitting together to disconnect the fitting from the power conversion system.
  6. Repeat step 4 and step 5 for the other tube fitting at the battery flange.
  7. Release the clip that attaches the tube to the HV battery AC inlet harness, and remove the tube from the vehicle.
  8. Install plugs into the power conversion system and the battery flange.
  9. Wipe up any spilled coolant.
    Caution:
    Spilled coolant can create an electrical path.

Install

  1. Wipe up any spilled coolant.
    Caution:
    Spilled coolant can create an electrical path.
  2. Make sure that the o-rings are not damaged and that they are properly seated in the connector groove prior to inserting the tube into the power conversion system. Replace components as necessary.

  3. Lubricate the coolant output tube o-rings with Silaramic lubricant.
  4. Remove the plugs from the power conversion system and the battery flange.
  5. Install the coolant output tube into the power conversion system and the battery flange.
  6. Firmly press down on the tube fittings, to make sure that the fittings are securely connected.
    Caution:
    Verify that both clips have fully engaged the barb on the power conversion system and battery flange, and then pull up on the fittings to check retention.
