Additional Notes
- The Valtra (Valmet) T4 Active cooling system capacity is 28 liters across all six variants — the T144 A, T154 A, T174e A, T194 A, T214 A, and T234 A — covering the full 2014-2021 model range. A uniform capacity across variants of differing power outputs indicates a shared cooling system architecture rather than engine-specific cooling volumes.
- The 28-liter figure represents the total cooling system fill volume, which in agricultural tractors typically encompasses the engine block, cylinder head passages, radiator, and associated hoses and reservoir. A capacity of this size is consistent with large-displacement multi-cylinder diesel engines used in high-horsepower agricultural machinery.
- Coolant level checks are specified at 10-hour intervals under normal use conditions. In tractor operation, 10 hours corresponds roughly to a standard working day, making the check interval effectively a daily inspection requirement during active use.
- The coolant change interval is set at 2400 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger structure means calendar time governs the interval when annual operating hours fall below 2400, while operating hours govern when usage is more intensive.
- All six T4 Active variants share identical check and change intervals — 10 hours for inspection and 2400 hours or 24 months for replacement. No variant carries a shortened or extended interval relative to the others, reflecting consistent cooling system service demands across the model range.
- The T174e A designation differs from the other five variants by including a lowercase "e" suffix, which in Valtra nomenclature typically denotes an engine variant distinction. Despite this difference, the T174e A carries the same 28-liter capacity and identical service intervals as the remaining T4 Active models in the 2014-2021 range.
