Additional Notes

  • The Fendt 800 Vario S4 cooling system capacity splits into two distinct values across the model range. The 822 Vario S4 holds 32 liters, while the 824, 826, and 828 Vario S4 models each hold 29 liters. A 3-liter difference of this kind typically reflects a larger engine block or additional cooling circuit volume in the higher-displacement configuration.
  • Each model in the 800 Vario S4 range carries a serial number break at the 00F05001 boundary, separating earlier production units (starting from serial suffix 0101, from 2016) from later ones (starting from serial suffix 00F05001, from 2018). Despite the production split, cooling system capacities and service intervals remain identical within each model across both serial ranges.
  • The 10-hour coolant check interval applies under normal use conditions across all listed 800 Vario S4 models. In agricultural machinery, a 10-hour check cycle corresponds roughly to daily inspection during active field seasons, given that a standard working day in heavy tractor use commonly falls within that range.
  • Coolant changes are specified at 2000 hours or 24 months, whichever comes first, under normal use conditions. The dual trigger — hours and calendar time — accounts for machines that accumulate operating hours slowly, where coolant degradation can still occur through oxidation and additive depletion over time even without heavy use.
  • The 32-liter cooling system capacity of the 822 Vario S4 is notably large relative to many agricultural tractors in its class. Capacities at this level are associated with engines producing significant thermal loads, where maintaining stable coolant volume is critical to consistent operating temperatures under sustained high-load conditions.
  • All eight listed configurations share an identical service interval structure: check at 10 hours, change at 2000 hours or 24 months. The uniformity across serial number ranges and model variants within the 800 Vario S4 line indicates a standardized cooling system service schedule regardless of the specific engine displacement or production period.
