Additional Notes

  • The Mazda CX-9 TC SKYACTIV-G 2.5 T cooling system holds 9.9 liters across all listed configurations, covering both FWD and AWD variants in the USA and CAN markets from 2015-2023 and 2016-2023 respectively.
  • A 9.9-liter cooling system capacity is consistent with a turbocharged four-cylinder engine in a mid-size crossover, reflecting the volume needed to circulate coolant through the engine block, cylinder head, heater core, and associated passages.
  • Under normal use conditions, the coolant change interval is set at 60,000 miles or 60 months, whichever comes first, applying equally to both the FWD and AWD configurations across USA and CAN markets.
  • The first change only condition carries a significantly extended interval of 120,000 miles or 120 months, which applies to the initial factory-fill coolant charge before transitioning to the standard 60,000-mile or 60-month cycle for subsequent changes.
  • The doubling of the interval under the first change only condition reflects the extended service life typically associated with long-life OEM coolant formulations used at the factory, which are formulated to last longer than conventional refill coolant.
  • The AWD configurations in both the USA and CAN markets share an identical 9.9-liter capacity and the same dual-interval structure as the FWD variants, indicating no difference in cooling system volume between the two drivetrain configurations.
  • The CAN-market FWD configuration carries a start year of 2015, while the CAN-market AWD configuration starts in 2016, representing the only model year variation across the listed specifications.
