Additional Notes

  • Across all five variants of the Fendt 300 Vario COM3b covered here, the 309, 310, 311, 312, and 313 Vario, the cooling system capacity is uniformly 29 liters, indicating a shared cooling circuit architecture regardless of model designation.
  • A 29-liter cooling system capacity is relatively substantial for agricultural tractors in the 300 series class, reflecting the thermal management demands of continuous field operation under load.
  • The check interval for the cooling system is set at every 10 hours of operation under normal use conditions, which aligns with the kind of frequent visual or level inspections typical of high-duty agricultural equipment.
  • The coolant change interval is specified at 2000 hours or 24 months under normal use conditions, meaning whichever threshold is reached first would govern the service event in practice.
  • The 24-month time-based limit on coolant changes means that even machines with low annual operating hours would still require a coolant change within two years, preventing degradation of corrosion inhibitors over time.
  • The 2012-2014 model years covered by serial number ranges beginning at 1001 for each variant all share identical service intervals, with no variation in check or change schedules across the 309 through 313 Vario lineup.
