Additional Notes

  • Across all New Holland PowerStar cooling system specifications, capacity varies based on cab configuration rather than engine size or model variant. Without a cab, all listed models hold 14 liters. With a cab, capacity rises to 16 liters. The 2-liter difference reflects the additional coolant volume required to serve the cab heating circuit.
  • The 2-liter cab-related capacity difference applies equally to the 2021 and later PowerStar 65, 75, 90, 100, 110, and 120, as well as the 2012-2018 T4.55, T4.65, and T4.75 PowerStar models, indicating a consistent cooling system architecture across both generations.
  • Coolant level checks are specified at 10-hour intervals for all listed models, regardless of cab configuration or model year. A 10-hour check interval is typical for agricultural equipment where daily or near-daily inspections are standard practice during active use seasons.
  • The 2012-2018 T4.55, T4.65, and T4.75 PowerStar models carry a coolant change interval of 1,200 hours or 24 months, whichever comes first. The dual-trigger format means a time-based limit applies even when hourly usage is low, preventing coolant degradation from age alone.
  • The 2021 and later PowerStar 65, 75, 90, 100, 110, and 120 models specify a coolant change interval of 3,600 hours, with no accompanying time-based limit stated in the specifications. At 3,600 hours, the change interval is three times longer than the 1,200-hour interval on the earlier T4-series models.
  • The extended 3,600-hour change interval on the 2021 and later models reflects the use of modern long-life coolant formulations, which are engineered to maintain corrosion inhibitor effectiveness over significantly longer service periods than conventional coolants.
  • All specifications listed are under normal use conditions. In agricultural equipment service manuals, normal use conditions typically represent standard field and transport operation, as opposed to severe conditions involving extreme temperatures, heavy dust, or prolonged idling.
