Mazda MX-5 / Miata, ND (EU)

Additional Notes

• The Mazda MX-5 ND (EU) SKYACTIV-G 1.5 cooling system holds 5.6 to 5.8 liters with a manual transmission, while the automatic transmission variant is fixed at 5.6 liters, placing the manual's upper fill point 0.2 liters above the automatic.
• The SKYACTIV-G 2.0 in both the 118 kW and 135 kW versions requires a noticeably larger coolant fill than the 1.5, ranging from 6.0 to 6.2 liters with a manual transmission, reflecting the greater displacement and associated cooling demands of the larger engine.
• On the 135 kW SKYACTIV-G 2.0 introduced from 2018, the automatic transmission cooling system capacity is listed as 5.8 to 6.0 liters, whereas the earlier 118 kW version of the same engine specifies 5.9 to 6.0 liters for the automatic, a slight downward shift in the lower bound of the range.
• Across all engine variants and model years covered, the coolant check interval is uniformly set at 40,000 km or 24 months, whichever comes first, applying under normal use conditions.
• Under normal use, the coolant change interval for all listed configurations is 100,000 km or 60 months, equivalent to a five-year or roughly 100,000 km service cycle.
• The initial service condition doubles the coolant change interval to 200,000 km or 120 months, meaning the first factory-filled coolant charge is specified to last ten years or twice the distance of subsequent normal-use changes.
• The check interval of 40,000 km or 24 months remains identical under both normal and initial service conditions across all configurations, indicating the inspection schedule is independent of whether the coolant is the original factory fill or a subsequent service fill.
• Both the 96 kW and 97 kW versions of the SKYACTIV-G 1.5, covering the 2015-2018 and 2018-onward variants respectively, share identical capacity figures and service intervals, with no difference in cooling system specifications between the two power outputs.
