Additional Notes

  • The Case-IH Optum CVT cooling system holds 21 liters, a capacity consistent with the demands of a high-output agricultural tractor engine requiring stable thermal management across extended field operations.
  • Both the Optum 270 CVT and Optum 300 CVT share an identical 21-liter cooling system capacity, indicating a common cooling architecture across the two power variants introduced in 2016.
  • The coolant change interval under normal use conditions is set at 48 months or 3,600 hours, whichever comes first, meaning time elapsed and accumulated engine hours are both tracked as triggers for service.
  • A 3,600-hour coolant change threshold reflects the kind of extended drain interval associated with modern long-life coolant formulations, which maintain corrosion inhibitor effectiveness over prolonged periods.
  • The coolant check interval is specified at every 10 hours of operation under normal use conditions, a notably frequent inspection point that reflects the importance of catching low coolant levels before they affect engine temperature regulation.
  • The 10-hour check interval stands in contrast to the 3,600-hour change interval, illustrating a distinction between routine monitoring and full fluid replacement within the same cooling system service schedule.
