Additional Notes
- The Mazda Xedos 6 1.6i carries a cooling system capacity of 6 liters, while the 2.0i V6 variant requires 7.5 liters, reflecting the greater thermal mass and additional coolant passages associated with a six-cylinder engine layout compared to a four-cylinder unit.
- The 1.5-liter difference in coolant capacity between the 1.6i and the 2.0i V6 is a relevant distinction when preparing the correct volume of pre-mixed or concentrated coolant fluid ahead of a service fill.
- Both engine variants share an identical check interval of every 10,000 km or 12 months, whichever comes first, under normal use conditions.
- The change interval for both the 1.6i and the 2.0i V6 cooling systems is set at 24 months under normal use, meaning coolant replacement is time-based rather than mileage-driven for both configurations.
- A 24-month change interval is relatively short by later industry standards and is consistent with older coolant formulations, such as conventional green IAT (Inorganic Additive Technology) types, which degrade in corrosion inhibitor effectiveness more quickly than extended-life OAT or HOAT formulations.
