Additional Notes
- The Hyundai KONA EV 64 kWh carries a coolant system capacity of 12.5 to 13.4 liters across all listed configurations from 2018-2023, with the range reflecting normal fill variation between a service top-up and a full system refill.
- Two distinct reservoir cap types appear in the 2018-2019 64 kWh specifications: one identified by a hot radiator emblem cap with green fluid, and another by a mechanic emblem cap with blue fluid. Each cap type corresponds to a separate cooling circuit, as electric vehicles commonly use multiple independent loops to manage battery, motor, and cabin thermal systems.
- The hot radiator emblem cap with green fluid entry for 2018-2019 carries no change interval in the specifications, only a capacity figure of 12.5 to 13.4 liters under normal use conditions.
- For the mechanic emblem cap with blue fluid on the 2018-2019 64 kWh, the normal use interval is set at 300,000 km or 24 months, whichever comes first.
- A first change only interval of 600,000 km or 48 months is listed for the mechanic emblem cap with blue fluid on the 2018-2019 64 kWh, meaning the extended interval applies exclusively to the initial factory fill before reverting to the standard 300,000 km or 24-month cycle.
- The 2019-2023 64 kWh retains the same capacity range of 12.5 to 13.4 liters and the same interval structure as the later 2018-2019 entries, with a normal use interval of 300,000 km or 24 months and a first change only interval of 600,000 km or 48 months for the mechanic emblem cap with blue fluid.
