Additional Notes
- The 300 Euro 4 with the 3616 engine carries a cooling system capacity of 14.2 liters in standard cab configurations, a volume consistent with a full system service fill that accounts for the radiator, engine block passages, heater core, and associated hoses.
- The Double Cab variant of the Hino Dutro / 300 series Euro 4 with the 3616 engine requires 15.2 liters of coolant, reflecting the additional plumbing associated with the extended cab layout and its larger heater circuit.
- The 1.0-liter difference between the standard cab at 14.2 liters and the Double Cab at 15.2 liters represents a meaningful distinction when performing a complete coolant drain and refill, as underfilling by that margin could leave portions of the system without adequate fluid coverage.
- Both capacity figures are specified under normal use conditions, meaning neither value applies to a severe-duty or first-change-only service scenario.
