Additional Notes

  • The New Holland TVT cooling system capacity is 25 liters across all six variants covered in the 2004-2007 period, spanning the TVT135, TVT145, TVT155, TVT170, TVT190, and TVT195. A uniform capacity of this level across an entire model range typically reflects a shared engine block and cooling jacket design rather than variant-specific engineering differences.
  • The 25-liter figure represents a service fill capacity, meaning the volume required to refill the cooling system during a standard drain and refill procedure. Cooling system capacities of this magnitude are common in high-horsepower agricultural tractors, where sustained heavy-load operation demands a large thermal reservoir to maintain stable engine temperatures.
  • Coolant checks are specified at 250-hour intervals under normal use conditions. In agricultural equipment, a 250-hour check interval aligns with routine seasonal service points, allowing inspection of coolant level, concentration, and condition without requiring a full drain.
  • The coolant change interval is set at 1000 hours or 12 months, whichever comes first, under normal use conditions. The dual-trigger structure means time-based degradation of coolant additives is accounted for even in lower-utilization applications where the hour threshold may not be reached within a calendar year.
  • The TVT190 is listed for the 2004-2006 period, while the TVT195 covers 2006-2007. Both share the identical 25-liter capacity and the same 250-hour check and 1000-hour/12-month change intervals, indicating no cooling system specification differences between the two variants despite the model transition.
