Additional Notes

  • The Valtra (Valmet) T5 Direct cooling system capacity is uniform at 28 liters across all variants in the lineup, covering the T145, T155, T175, T195, T215, T235, and T255 Direct. A 28-liter figure is consistent with large agricultural tractor cooling systems, where substantial coolant volume is needed to manage heat from high-displacement diesel engines under sustained field loads.
  • All seven T5 Direct variants share an identical coolant check interval of every 10 hours of operation under normal use conditions. A 10-hour check interval is notably short and reflects the demanding thermal environment of agricultural machinery, where coolant level and condition can be affected by extended high-load work cycles.
  • The coolant change interval for all T5 Direct variants is set at 2400 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger structure means time-based degradation is accounted for even in machines that accumulate hours slowly, since coolant additives break down chemically over time regardless of engine runtime.
  • The consistency of the 28-liter capacity across the T145 through T255 Direct variants, despite the range spanning meaningfully different power outputs, suggests a shared engine block architecture or cooling circuit design across the T5 Direct series introduced from 2021.
  • The 2400-hour service threshold places coolant changes on a long-interval schedule relative to other fluid systems on agricultural tractors, which typically see more frequent oil and filter changes. At average seasonal usage rates, 2400 hours can represent several years of field operation, making the 24-month calendar limit the more frequently triggered condition for lower-utilization machines.
