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:
-
Position the coolant service fixture drain hose into the coolant waste
reservoir, a bucket, or other appropriate used coolant receptacle.
1 Hose to coolant waste reservoir, bucket, or other appropriate used coolant receptacle 2 Hose to coolant drain tool CAUTIONNever allow the pressure inside the HV battery to exceed 25 psi. -
Slowly open the valve on the drain tool.
NoteThe 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.
Refill
CAUTION
Only fill the battery with the specified coolant. In
this manual, refer to 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.
NoteThe fill tool has a pressure regulator to prevent the battery from being overpressurized.NoteWatch 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.
NoteThe 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.
