Additional Notes
- The Honda Odyssey 3.5 V6 carries two distinct coolant capacity figures: an overhaul capacity of 9.4–9.7 liters and a service fill capacity of 7–7.5 liters. The overhaul figure reflects a fully drained and refilled system, while the service fill figure accounts for residual coolant remaining in the system during a standard maintenance drain.
- The gap between the 7–7.5 liter service fill and the 9.4–9.7 liter overhaul capacity on the 2005-2010 Odyssey 3.5 V6 is approximately 2–2.7 liters, representing the volume of coolant that typically remains trapped in the engine block, heater core, and other passages during a routine service drain.
- The cooling system service interval for the Odyssey 3.5 V6 (2005-2010) is governed by a flexible schedule tied to the on-board maintenance system rather than a fixed mileage or time interval. The on-board maintenance system monitors driving conditions and calculates service needs accordingly, adjusting the interval based on actual vehicle operation.
