Additional Notes

  • The Valtra (Valmet) N5 Active cooling system capacity is 18 liters across all four variants: the N135, N155, N155E, and N175 Active.
  • An 18-liter cooling system capacity is relatively substantial for agricultural tractor applications, reflecting the thermal management demands of high-torque diesel engines in this power class.
  • The coolant check interval is set at 10 hours of operation, which aligns with a daily or pre-shift inspection routine common in professional agricultural use.
  • The coolant change interval is specified at 2400 hours or 24 months under normal use conditions, meaning whichever threshold is reached first would govern the service event.
  • A 2400-hour or 24-month change interval is consistent with modern extended-life coolant formulations, which are engineered to maintain corrosion inhibitor effectiveness over longer service periods compared to conventional coolants.
  • The N135, N155, N155E, and N175 Active variants all share identical capacity and interval specifications, indicating no differentiation in cooling system service requirements across the engine output range within the N5 Active lineup from 2021 onward.
