Additional Notes
- The Mazda MX-5 / Miata NC (EU) cooling system holds 7.5 liters across all four configurations covered, spanning both the 1.8 and 2.0 engine variants from 2005-2015.
- A 7.5-liter cooling system capacity is a relatively modest figure, consistent with the compact displacement and lightweight character of a two-seat roadster platform.
- Neither engine displacement nor the 2011 production split produces any variation in cooling system capacity, with the 7.5-liter figure applying uniformly to the 1.8 and 2.0 across both generational halves.
- Under normal use conditions, a coolant level check is specified at 40,000 km or every 24 months, whichever comes first, for all four configurations.
- The coolant change interval under normal use is set at 200,000 km or 132 months, the latter equaling 11 years, which places this among the longer-duration fluid service intervals found in modern passenger vehicles.
- The 132-month change interval reflects the use of long-life coolant formulations, which are engineered to maintain corrosion inhibitor effectiveness and freeze protection over extended periods without requiring earlier replacement under normal conditions.
- The gap between the check interval (40,000 km / 24 months) and the change interval (200,000 km / 132 months) means the cooling system is inspected multiple times before a full fluid replacement is due.
