Additional Notes

  • The Case IH Maxxum CVT cooling system capacity is 21 liters across all listed variants, from the Maxxum 110 CVT through the Maxxum 145 CVT. A consistent capacity across multiple power ratings within the same model family typically reflects a shared engine block or cooling circuit architecture.
  • The 21-liter figure represents a service fill capacity, meaning the volume required when refilling the cooling system during a drain-and-refill service. Overhaul or full system flush procedures on large agricultural engines can sometimes require additional fluid to purge air pockets from the circuit.
  • The change interval is specified as 48 months or 3,600 hours, whichever comes first, under normal use conditions. The dual-trigger format is standard practice for agricultural equipment, where calendar time and operational hours can accumulate at very different rates depending on seasonal workloads.
  • A 3,600-hour change threshold is notably high relative to many other fluid systems on agricultural tractors, reflecting the long-life coolant formulations typically used in modern heavy-duty cooling systems. Reaching 3,600 hours before 48 months would require averaging roughly 75 hours of operation per week.
  • The coolant level check interval is set at every 10 hours across all listed variants. A 10-hour check frequency aligns with daily pre-operation inspection routines common in agricultural field work, where tractors may run for extended continuous periods.
  • The Maxxum 110 CVT, 120 CVT, and 130 CVT share a 2015-2020 production window, while the Maxxum 115 CVT, 125 CVT, 135 CVT, and 145 CVT are listed with a 2016 start year. Despite the different introduction years, all variants carry identical cooling system capacities and service intervals.
  • All specifications are listed under normal use conditions. In agricultural equipment contexts, normal use generally refers to standard field operation as opposed to severe-duty cycles involving extreme ambient temperatures, heavy continuous loads, or highly dusty environments that could accelerate coolant degradation.
