Additional Notes
- The Honda CR-V e:FCEV ZC4 runs two separate coolant circuits, each with its own capacity figures — one serving the electric motor system and one serving the fuel cell system.
- For the electric motor cooling circuit, the initial fill capacity is 7.6 liters, which reflects the total volume required when the system is dry, such as during a full overhaul or component replacement.
- The service fill capacity for the electric motor cooling circuit is 3.9 liters, representing the volume needed during a routine coolant change where residual fluid remains in the system.
- The fuel cell cooling circuit carries a notably larger initial fill capacity of 14.9 liters, indicating a substantially greater total fluid volume within that circuit compared to the electric motor circuit.
- The service fill capacity for the fuel cell cooling circuit is 5.5 liters, which is the working volume used when performing a standard coolant service rather than a full system drain.
- Both cooling circuits on the ZC4 operate on a flexible service interval determined by the on-board maintenance system, meaning the vehicle itself monitors conditions and signals when service is due rather than following a fixed mileage or time schedule.
