Additional Notes

  • All Valpadana 6600 Series variants covered in these specifications share a base cooling system capacity of 6.5 liters, which represents the standard engine circuit fill without any supplemental climate control hardware.
  • When a cabin heating or air conditioning unit is fitted, the total coolant capacity rises to 7.5 liters across all listed configurations, reflecting the additional volume held within the cabin heat exchanger circuit.
  • The 1.0-liter difference between the base and cabin-equipped capacity figures is consistent across all eight variants, regardless of engine type or transmission configuration.
  • The coolant change interval is set at 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger structure accounts for machines that accumulate operating hours slowly, ensuring time-based degradation of coolant additives is also addressed.
  • The 6660 sub-series uses the Yanmar 4TNV84T engine, a turbocharged four-cylinder diesel, while the 6675 sub-series uses the John Deere 4024 HF295, also a four-cylinder diesel. Despite the difference in engine origin, both sub-series share identical cooling system capacities and service intervals.
  • Within each engine family, four transmission or configuration variants are listed: ARM, ISM, ISR-REV, and VRM. None of these variants alter the cooling system capacity or change interval, indicating the cooling circuit design is uniform across transmission types within each sub-series.
  • The 1,000-hour service threshold is a common benchmark in agricultural and compact utility machinery, where annual usage can vary widely depending on seasonal workloads, making the 12-month calendar limit a practical parallel constraint.
