Additional Notes

  • The Hürlimann XB T-TB COM3 cooling system capacity is 11 liters across all listed variants, covering the XB 85 T, XB 85 TB, XB 100 T, and XB 100 TB configurations for 2010-2016. An 11-liter figure is consistent with a mid-range agricultural tractor engine cooling circuit, accounting for the radiator, engine block passages, and associated hoses.
  • The 11-liter capacity is uniform regardless of serial number range, meaning units up to serial 1001 and those from serial 1002 through 5001 share the same cooling system volume. No capacity difference exists between the earlier and later production batches within the same model designation.
  • The T and TB suffix variants also share the identical 11-liter capacity. The TB designation typically denotes a turbocharged configuration with a front loader provision, yet the cooling system volume remains unchanged relative to the standard T variant across both the 85 and 100 power ratings.
  • Coolant level checks are specified at 10-hour intervals under normal use conditions. A 10-hour check interval is notably short and reflects the demanding thermal environment of agricultural machinery, where coolant loss through minor seepage or cap pressure cycling can occur more readily than in on-road vehicles.
  • The coolant change interval is set at 1000 hours or 24 months, whichever comes first, under normal use conditions. The dual-trigger format means a tractor used infrequently enough to reach 24 months before accumulating 1000 hours would still require a coolant change based on calendar time alone, since coolant additives degrade over time independently of engine runtime.
  • All eight listed configurations share the same check and change intervals, indicating no differentiation in service scheduling between the XB 85 and XB 100 power levels or between the T and TB body variants for the 2010-2016 model years.
