Additional Notes
- The Kia EV9 MV (USA / CAN) carries two separate cooling circuits, one serving the electric motor and one serving the high voltage battery, each with its own listed capacity figure.
- On the 76.1 kWh (160 kW) RWD and 99.8 kWh (150 kW) RWD configurations, the electric motor cooling circuit holds 6.16 liters, while the high voltage battery circuit holds 14.32 liters, making the battery thermal management loop more than twice the volume of the motor loop.
- The 99.8 kWh (283 kW) AWD configuration carries slightly larger capacities in both circuits, with 6.53 liters for the electric motor and 14.35 liters for the high voltage battery, reflecting the added thermal demands of the dual-motor drivetrain.
- Under normal use conditions, all three configurations share a coolant change interval of 24,000 miles or 24 months, whichever comes first.
- A separate first-change-only interval of 120,000 miles or 120 months applies across all three configurations, indicating an extended initial fill designed to remain in service far longer before the first scheduled replacement.
- The gap between the normal interval of 24,000 miles / 24 months and the first-change-only interval of 120,000 miles / 120 months is substantial, reflecting that the factory-fill coolant is formulated for a significantly longer initial service life than subsequent fills.
- All six specification rows carry the note referencing a hot radiator emblem cap, indicating that the coolant access point on the EV9 is located behind or integrated with the front emblem rather than a conventional hood-mounted reservoir cap.
