Additional Notes
- The Honda HR-V RU5/RU6 1.8 2WD cooling system carries a service fill capacity range of 5.25 to 5.98 liters, meaning the actual refill volume can vary within that band depending on how completely the system drains and how air pockets are purged during the procedure.
- The 1.8 AWD variant holds a fixed service fill capacity of 5.25 liters, which sits at the lower bound of the range specified for the 2WD configuration.
- Both the 2WD and AWD configurations share a flexible service interval governed by the on-board maintenance system, meaning coolant service timing is determined by the vehicle's own monitoring rather than a fixed mileage or time schedule.
- The 5.25-liter figure appears in both drivetrain configurations, suggesting the base cooling system volume is consistent across the 2WD and AWD layouts for the 1.8-liter engine in the HR-V RU5/RU6.
- All capacities listed are designated as service fill values, which represent the amount of coolant added during a drain-and-refill service rather than the total system volume measured during a full overhaul or component replacement.
