Additional Notes
- Both the KONA EV 48.4 kWh and the 65.4 kWh variants share an identical coolant capacity range of 12.9 to 14.27 liters, despite differing battery sizes.
- The capacity is expressed as a range rather than a fixed value, which reflects normal variation in how much fluid the cooling system accepts depending on fill method and air purging during service.
- Both configurations carry a note referencing the hot radiator emblem cap, meaning the coolant reservoir or cap access point is located behind or integrated with the front emblem, a design specific to the Hyundai KONA EV.
- The listed capacity applies under normal use conditions, meaning standard operating environments rather than severe or high-stress duty cycles.
- A cooling system capacity in the 12.9 to 14.27 liter range is relatively substantial for an electric vehicle, reflecting that the thermal management circuit covers not only the motor and inverter but also the high-voltage battery pack.
