Additional Notes
- The 2011-2013 Honda Odyssey RL5 3.5 V6 cooling system carries two distinct capacity figures: 10 liters for an overhaul and 7.3 liters for a service fill. The overhaul capacity reflects a fully drained system, including components such as the engine block, heater core, and all hoses, while the service fill represents the amount needed during a routine coolant exchange without a complete drain.
- The 7.3-liter service fill capacity on the 2011-2013 3.5 V6 indicates that a standard coolant flush does not evacuate the entire system volume, leaving roughly 2.7 liters of residual fluid within the circuit.
- For the 2014-2017 3.5 V6, only a single capacity figure of 7.3 liters is listed, which aligns with the service fill value seen in the earlier model years.
- Both the 2011-2013 and 2014-2017 configurations share the same 7.3-liter service fill figure, indicating consistency in the cooling system's serviceable volume across the full 2011-2017 production span.
- Service intervals for both configurations are governed by a flexible schedule tied to the on-board maintenance system, meaning coolant service is triggered by the vehicle's monitoring logic rather than a fixed mileage or time interval.
