Additional Notes

  • The JetMax 250i (CF250T-6A) cooling system carries a total capacity of 2.1 liters split across the radiator and engine block, with an additional 0.3 liters held in the reservoir, bringing the full system volume to 2.4 liters when both are serviced together.
  • The 0.3-liter reservoir capacity is separate from the primary 2.1-liter radiator and engine fill, meaning a top-up service limited to the reservoir alone accounts for only a fraction of the total coolant volume.
  • Under normal use conditions, the specified change interval for the JetMax 250i (CF250T-6A) cooling system is 24 months, which is a time-based interval rather than one tied to mileage or operating hours.
