Additional Notes

  • The Fendt 800 Vario COM3 cooling system capacity is 21 liters across the 818 Vario, 820 Vario, and 820 Vario GreenTec configurations. A 21-liter figure represents a full cooling system fill, accounting for the engine block, cylinder head passages, radiator, and associated hoses.
  • The 818 Vario (2007-2009) carries a coolant change interval of 2000 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger structure means time elapsed can mandate a change even when the hour threshold has not been reached.
  • The 820 Vario (2007-2009) shares the same 21-liter capacity and 2000-hour/24-month change interval as the 818 Vario, indicating no divergence in cooling system specification between those two variants despite differing engine outputs.
  • The 820 Vario GreenTec (2008-2010) also holds 21 liters and follows the 2000-hour/24-month normal-use interval, placing the GreenTec variant in full alignment with the broader 820 Vario cooling system specification.
  • All three configurations apply the normal use condition to the 2000-hour/24-month interval. In agricultural equipment contexts, normal use typically refers to standard field and transport operation without sustained extreme thermal loading or contaminated environments.
