Additional Notes
- The Mazda 929 (EU) cooling system capacity holds at 7.5 liters across the 2.0, 2.0i, 2.2, and 2.2i variants, indicating a consistent cooling circuit volume regardless of whether the engine is naturally aspirated or fuel-injected within that displacement range.
- The 3.0i variant carries a noticeably larger cooling system capacity of 9.4 liters, which reflects the greater thermal mass and larger engine block associated with a six-cylinder configuration compared to the four-cylinder units in the lineup.
- The 929 2.0 (1984-1987) specifies a change interval expressed purely in time at 24 months, with no distance figure attached to the normal use condition.
- From 1987 onward, all variants — the 2.0i, 2.2, 2.2i, and 3.0i — share a dual-condition change interval of 40,000 km or 48 months under normal use, whichever comes first, representing a longer time-based interval than the earlier 2.0 specification.
- The shift from a 24-month interval on the 1984-1987 2.0 to a 48-month interval on the 1987-1992 variants marks a doubling of the time-based service period between the earlier and later model year specifications.
- A 9.4-liter cooling system, as seen on the 929 3.0i, requires a proportionally larger volume of coolant at each service fill, which has a direct bearing on the quantity of antifreeze concentrate needed to maintain the correct mixture ratio.
