Additional Notes
- All four configurations of the Mazda MX-5 / Miata NB (EU) share an identical cooling system capacity of 6 liters, applying equally to both the 1.6 and 1.8 engine variants across the 1997-2005 production span.
- A 6-liter cooling system capacity is a moderately sized fill for a lightweight two-seat roadster, reflecting the relatively compact inline-four engines used in both displacement variants.
- The coolant check interval is set at 30,000 km or 24 months under normal use conditions, meaning whichever threshold arrives first triggers the inspection requirement.
- The coolant change interval extends to 90,000 km or 24 months under normal use conditions. The 24-month time limit applies regardless of mileage accumulation, so low-mileage vehicles still reach a change point at the two-year mark.
- No variation in capacity or service intervals exists between the 1.6 and 1.8 engine configurations, with both sharing the same 6-liter fill, 30,000 km/24-month check schedule, and 90,000 km/24-month change schedule.
- The specifications are identical between the pre-2000 and post-2000 model year groupings for both engine sizes, indicating no cooling system service changes were introduced at the 2000 production boundary.
