Additional Notes

  • The Case IH Quantum N cooling system capacity varies by generation. The 2008-2014 models (75N, 85N, 95N, and 105N) hold 10 liters, while the 2018 and later models (80N, 90N, 100N, and 110N) hold 14 liters, representing a 4-liter increase across the updated lineup.
  • When a cabin heater circuit is included, coolant capacity rises by 2 liters across all Quantum N variants. The 2008-2014 models reach 12 liters with cabin, and the 2018 and later models reach 16 liters with cabin. The cabin addition applies uniformly regardless of engine output rating.
  • The 16-liter figure on the 2018 and later Quantum N models with cabin represents the largest cooling system capacity in the range. A higher total volume generally means the system can absorb and dissipate more heat, which is relevant for tractors operating under sustained load conditions.
  • A coolant check interval of 10 hours applies to all Quantum N variants across both generations. In agricultural equipment, a 10-hour check interval reflects the short daily operating cycles typical of field work, where coolant level and condition can shift quickly under variable load and ambient temperature.
  • The coolant change interval is set at 1200 hours or 24 months for all Quantum N models, whichever comes first. The dual-trigger structure means time-based degradation is accounted for even when annual operating hours fall short of the 1200-hour threshold.
  • The 1200-hour or 24-month change interval is consistent across both the 2008-2014 and 2018 and later Quantum N generations, despite the difference in system capacity. The interval applies under normal use conditions as specified in the data.
  • Within the 2008-2014 generation, four power variants are listed: the 75N, 85N, 95N, and 105N. All four share identical cooling system capacities and service intervals, indicating the cooling system architecture was standardized across that engine output range rather than scaled per horsepower rating.
  • Within the 2018 and later generation, the 80N, 90N, 100N, and 110N also share identical cooling system capacities and service intervals. As with the earlier generation, the cooling system specifications are uniform across the power variants rather than differentiated by output level.
