Additional Notes

  • The Yamaha X-Max 300 (USA) cooling system holds a total capacity of 1.1 liters, which represents the full system fill volume used when draining and refilling the entire cooling circuit.
  • A separate reservoir capacity of 0.18 liters is specified alongside the main system volume, reflecting the overflow or expansion tank that holds coolant outside the primary circuit.
  • The 2018-2020 and 2021 configurations share identical capacities of 1.1 liters for the main system and 0.18 liters for the reservoir, indicating no change in cooling system volume between those model year groups.
  • A 36-month change interval is specified under normal use conditions for both the 2018-2020 and 2021 configurations, meaning coolant replacement is tied to elapsed time rather than mileage in normal operating circumstances.
