Additional Notes
- Both the 2.0i and the 2.5i V6 share an identical cooling system capacity of 7.5 liters, which represents the total volume of the cooling circuit including the radiator, engine block passages, heater core, and expansion reservoir.
- A 7.5-liter cooling system capacity is a moderately sized figure for passenger cars of the early-to-mid 1990s, consistent with engines in the 2.0 to 2.5-liter displacement range that generate enough heat to require a well-developed coolant circuit.
- The Mazda MX-6 (EU) coolant change interval is set at 24 months under normal use conditions for both the 2.0i and the 2.5i V6, meaning a calendar-based schedule governs replacement rather than a mileage threshold alone.
- A 24-month coolant change interval reflects the service life of conventional ethylene glycol-based antifreeze formulations, which degrade in pH buffering capacity and corrosion inhibitor effectiveness over roughly two years regardless of distance driven.
- The normal use condition tied to the 24-month interval and 7.5-liter capacity applies uniformly across both engine variants in the 1992-1996 production span, with no differentiation recorded between the four-cylinder and V6 configurations for coolant service scheduling.
