Fendt 800 Vario COM2

Additional Notes

• Across all listed variants of the Fendt 800 Vario COM2 — the 815, 817, and 818 Vario TMS — the cooling system capacity is uniformly specified at 20 liters. In agricultural machinery of this class, a 20-liter cooling system reflects the demands of high-displacement diesel engines operating under sustained load conditions typical of field work.
• The coolant change interval is set at 2000 hours or 24 months, whichever comes first, for all six configurations listed. The dual-trigger format is standard practice for heavy equipment, ensuring fluid degradation is addressed by calendar time even when annual operating hours are low.
• Each row is designated for normal use conditions. In the context of fluid service intervals, a normal use classification generally corresponds to standard operating environments without the accelerated contamination or thermal stress that would shorten intervals under severe use definitions.
• The 815 and 817 Vario TMS variants each appear in two distinct serial number ranges: an earlier group running from serial suffix 0000 through 2000, covering model years 2002-2005, and a later group beginning at serial suffix 2001, covering 2006-2009. Despite the serial number boundary, the cooling system capacity and change interval remain identical across both ranges for each variant.
• The 818 Vario TMS follows the same serial number split structure as the 815 and 817, with an early range spanning 2002-2005 and a later range from 2006-2007. As with the other variants, the 20-liter capacity and 2000-hour/24-month interval apply uniformly to both serial ranges.
• The consistency of the 20-liter capacity across the 815, 817, and 818 model designations — which differ in engine output — suggests a shared cooling system architecture within the 800 Vario COM2 platform rather than cooling circuit sizing scaled individually to each power rating.
