Additional Notes

  • The Fendt 800 Vario COM3b cooling system capacity is listed as a range of 35-45 liters across all five variants, which reflects the variable volume that a large agricultural tractor cooling circuit can hold depending on exact configuration and fill conditions.
  • A 10-liter spread between the minimum and maximum capacity values is notable, as cooling systems in heavy machinery of this class often include expansion tanks, intercooler circuits, and cab heating loops that contribute to total system volume variability.
  • The 819, 822, 824, 826, and 828 Vario Stage IIIb / EPA 4i variants all share an identical capacity specification of 35-45 liters, indicating no differentiation in cooling system volume across the model range for the 2011-2016 period.
  • All five variants carry a coolant change interval of 24 months under normal use conditions, meaning the time-based interval applies to standard operating environments rather than extended or severe service scenarios.
  • A 24-month coolant change interval is a calendar-based service schedule, which is common for modern coolant formulations where degradation of corrosion inhibitors occurs over time regardless of machine operating hours.
  • Each variant is identified by a distinct serial number prefix, with the 819 using 832, the 822 using 833, the 824 using 834, the 826 using 835, and the 828 using 836, all beginning from sequence 0101 onward within the 2011-2016 span.
