Additional Notes

  • The Valtra (Valmet) N4 Versu cooling system capacity is 18 liters across all four variants — the N134, N154, N154e, and N174 — for the 2015-2021 model years, indicating a consistent system volume regardless of engine output differences between variants.
  • An 18-liter cooling system capacity is a moderately large fill volume, typical of agricultural tractor engines where sustained high-load operation demands substantial thermal management.
  • The coolant check interval is set at 10 hours under normal use conditions across all N4 Versu variants, reflecting the frequency at which the system level should be inspected during regular operation.
  • The coolant change interval for the N134, N154, N154e, and N174 Versu is 2400 hours or 24 months under normal use conditions, whichever comes first, meaning both an operational hour threshold and a calendar-based limit apply simultaneously.
  • A 24-month calendar interval running alongside the 2400-hour threshold means that a machine with lower annual usage would still require a coolant change within two years, independent of accumulated engine hours.
  • The N154e Versu shares the same 18-liter capacity and 2400-hour/24-month change interval as the non-emissions-variant N154, despite the "e" designation typically indicating an engine configuration with additional emissions-related components.
