Additional Notes

  • The Fendt 300 Vario S4 cooling system capacity is 24 liters across all variants in the 309-313 range, covering both Power and Profi trim levels from 2015-2021. A 24-liter figure is consistent with a full system fill, accounting for the engine block, radiator, and associated hoses rather than a partial top-up volume.
  • Under normal use conditions, the coolant change interval is set at 2000 hours or 24 months, whichever comes first. The dual-trigger structure means time elapsed can mandate a change even when the hour threshold has not been reached, which is common in agricultural equipment that may sit idle during off-seasons.
  • A separate first-change-only interval of 50 hours applies to all 309-313 Vario variants in both Power and Profi configurations. An early flush at 50 hours is standard practice on new or rebuilt cooling systems to remove manufacturing residues, metal particles, and initial fluid contamination before the long-term service schedule takes effect.
  • The coolant level check interval under normal use is 10 hours across all listed variants. A 10-hour check frequency reflects the high thermal and mechanical demands placed on agricultural tractor cooling systems during intensive field work, where small leaks or evaporation losses can escalate quickly.
  • The Power trim variants carry internal codes ending in /23/ (e.g., 346/23/0101), while Profi trim variants carry codes ending in /21/ (e.g., 346/21/0101). Despite the different trim designations, both share identical cooling system capacities and service intervals within each model number.
  • Each model in the 309-313 range uses a sequential internal code series: 346 for the 309, 347 for the 310, 348 for the 311, 349 for the 312, and 350 for the 313. All ten configurations across these five model numbers share the same 24-liter capacity and the same two-tier service schedule of 50 hours for the first change and 2000 hours or 24 months thereafter.
