Additional Notes

  • The Honda Odyssey RL6 3.5 V6 cooling system capacity falls within a narrow range of 6.38 to 6.42 liters, which is consistent with a full cooling system service fill rather than a partial drain-and-refill procedure.
  • The 0.04-liter spread between the minimum and maximum capacity values reflects normal variation in fill levels across individual vehicles, such as differences in air pocket purging during the refill process.
  • The service interval for the 3.5 V6 cooling system is governed by a flexible schedule tied to the on-board maintenance system, meaning the vehicle's computer monitors operating conditions and calculates when service is due rather than following a fixed mileage or time-based interval.
