Additional Notes
- The Mazda MX-3 (EU) 1.6i carries a cooling system capacity of 6 liters, while the 1.8i V6 requires 7.5 liters, reflecting the greater thermal demands of the larger six-cylinder engine.
- A 1.5-liter difference in coolant capacity separates the two engine variants, a gap that is relevant when calculating the correct volume of coolant concentrate and water needed to achieve a proper mixture ratio during a full system fill.
- Both the 1.6i and the 1.8i V6 share an identical change interval of 24 months under normal use conditions, meaning neither engine configuration calls for more frequent coolant renewal than the other despite the difference in displacement and cylinder count.
- The 24-month interval applies to normal use conditions across the 1992-1998 production span for both variants, so vehicles operated under more demanding conditions would fall outside the scope of what these specifications address.
- The 7.5-liter figure for the 1.8i V6 cooling system represents a full system capacity, which typically accounts for the radiator, engine block passages, heater core, and hoses combined, making it the reference volume for a complete drain and refill rather than a partial top-up.
