  1. Remove the thumbnuts and washers from the coolant service fixture.
  2. Place the coolant service fixture over the coolant Rapid Mate.
  3. Install the washers and thumbnuts.
  4. Prepare the coolant drain tool:
    1. Close the valve.
    2. Connect a compressed air line to the drain tool.
    3. Connect the coolant service fixture fill hose to the drain tool.

    Note
    The drain tool has a pressure regulator to prevent the HV battery from being overpressurized.
  7. Once approximately 2 gallons (7.5 liters) of coolant has been removed, close the valve on the drain tool, then remove the coolant service fixture from the HV battery.

Refill

Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
Only fill the battery with the specified coolant. In this manual, refer to Fluids.
  1. Fill the battery coolant fill tool with the specified coolant.
  2. Connect the coolant service fixture to one of the hoses on the fill tool.
  3. Position the other hose on the coolant service fixture to drain into a bucket or other appropriate used coolant receptacle.
  4. Ensure that the switch on the fill tool is set to "Dispense".
  5. Open the fill valve on the fill tool.
  6. Pump the hand pump to fill the battery with the specified coolant.

    Note
    The fill tool has a pressure regulator to prevent the battery from being overpressurized.
    Informational PurposesAn informational icon, calling your attention
    Note
    Watch the coolant level in the fill tool. If the coolant level drops too low, the fill tool pumps air into the battery and the procedure has to be repeated.
  7. When the battery is nearly full, the coolant starts to rise in the drain hose. Close the fill valve when the coolant exiting the battery is mostly free of air bubbles.
    Informational PurposesAn informational icon, calling your attention
    Note
    The coolant exiting the battery does not need to be completely free of air bubbles.
  8. Open the relief valve on the fill tool.
  9. Remove the coolant service fixture from the HV battery.
    Tip: The 2 hoses on the coolant service fixture can be connected to each other for easier handling and storage.
