WASTE RESERVOIR
The HV battery retains approximately 2 gallons (7.5 liters) of coolant
when it is removed from the vehicle. Follow this procedure to drain the
coolant before shipping the battery, or to refill a new or
remanufactured battery before installing it.
Drain
Warning: If the battery is suspected to have a coolant
leak, do not perform this procedure. Contact Service Engineering for
assistance.
Remove the thumbnuts and washers from the coolant service
fixture.
Place the coolant service fixture over the coolant Rapid Mate.
Install the washers and thumbnuts.
Prepare the coolant drain tool:
Close the valve.
Connect a compressed air line to the drain tool.
Connect the coolant service fixture fill hose to the drain
tool.

Caution: Never allow the pressure inside the HV battery to
exceed 25 psi.
Slowly open the valve on the drain tool.
Note:The drain tool has a pressure regulator to
prevent the HV battery from being overpressurized.
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.
HV Battery Coolant - Refill
Caution: Only fill the battery with the specified coolant. In
this manual, refer to General Information > Fluids and
Capacities > Fluids.
Fill the battery coolant fill tool with the specified coolant.
Connect the coolant service fixture to one of the hoses on the
fill tool.
Position the other hose on the coolant service fixture to drain
into a bucket or other appropriate used coolant receptacle.
Ensure that the switch on the fill tool is set to "Dispense".
Open the fill valve on the fill tool.
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.
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.
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.
Note: The coolant exiting the battery does not
need to be completely free of air bubbles.
Open the relief valve on the fill tool.
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.
