Additional Notes

  • The Valtra (Valmet) S6 Series cooling system capacity is 30 liters across all six variants — the S286, S316, S346, S376, S396, and S416 — indicating a uniform cooling system volume regardless of model designation within the range.
  • A 30-liter cooling system capacity is consistent with large agricultural tractors, where substantial engine displacement and extended operational loads require a high-volume coolant circuit to maintain stable thermal conditions.
  • Two service interval schedules apply to the S6 Series cooling system: a normal-use interval of 24 months and an extended-use interval of 60 months, with both tied to the same 30-liter capacity figure.
  • The 24-month normal-use interval represents a standard coolant change cycle, typically associated with conventional coolant formulations that degrade inhibitor packages more rapidly under routine operating conditions.
  • The 60-month extended-use interval is more than double the normal schedule, a duration generally associated with long-life or organic acid technology (OAT) coolant formulations, which maintain corrosion inhibitor effectiveness over a significantly longer service period.
  • The identical capacity and interval values across all six S6 Series variants — S286 through S416 — suggest a shared cooling system architecture across the entire model range introduced from 2023.
