Additional Notes

  • The Mazda MX-5 / Miata NC cooling system holds 7.5 liters across both the 118 kW and 125 kW engine variants produced from 2005-2010, placing both outputs on equal footing for service fill volume during standard coolant changes.
  • For the 2005-2010 models in both power outputs, the normal use interval is set at 60,000 miles or 60 months, meaning coolant replacement is expected on a five-year or distance cycle under standard operating conditions.
  • A first change only interval of 120,000 miles or 120 months applies to the 2005-2010 118 kW and 125 kW variants, which reflects the extended service life of the factory-fill coolant before the standard 60,000-mile/60-month cycle takes over for all subsequent changes.
  • The 118 kW engine in the 2010-2015 production period carries a slightly reduced cooling system capacity of 7.2 liters, down from the 7.5 liters specified for the same engine in the 2005-2010 period.
  • The 125 kW engine in the 2010-2015 period is listed with a capacity range of 7.3-7.6 liters rather than a fixed value, indicating a variable fill volume that may depend on specific trim or configuration within that production window.
  • Despite the capacity difference between the 118 kW and 125 kW engines in the 2010-2015 period, both share the same service intervals: 60,000 miles or 60 months for normal use, and 120,000 miles or 120 months for the first change only condition.
  • The first change only interval of 120,000 miles or 120 months for the 2010-2015 118 kW variant applies to a 7.2-liter system, meaning a full drain and refill of that volume is not required under normal conditions until that extended threshold is reached for the initial factory fill.
