Additional Notes

  • Every variant in the Valtra T4 HiTech lineup — T144 H, T154 H, T174e H, T194 H, T214 H, and T234 H — shares an identical cooling system capacity of 28 liters across the 2015-2021 model range, indicating a common engine cooling architecture despite the differing power outputs across the series.
  • A 28-liter coolant capacity is a substantial figure for an agricultural tractor, reflecting the large-displacement diesel engines used in heavy-duty machinery of this class, where sustained high-load operation demands significant thermal management volume.
  • The coolant check interval is set at 10 hours under normal use conditions, which aligns with the standard pre-shift or daily inspection routine common in professional agricultural operations, where tractors may accumulate operating hours rapidly during seasonal work.
  • The coolant change interval is specified at 2400 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger structure means calendar time governs the interval even when annual machine hours fall short of the 2400-hour threshold.
  • A 2400-hour service interval for coolant is relatively extended compared to lighter equipment, reflecting the use of heavy-duty long-life coolant formulations typically required in modern agricultural tractor cooling systems of this type.
  • The uniformity of the 28-liter capacity and the 2400-hour/24-month change interval across all six T4 HiTech variants from T144 H through T234 H suggests the cooling system specification was carried unchanged across the entire model family for the 2015-2021 period.
