New Holland TN-NA

Coolant capacity & service interval

New Holland TN-NA coolant capacity ranges from 10 to 12 liters. Service intervals include checking every 10 hours and changing every 1200 hours or 24 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The New Holland TN-NA series cooling system holds 10 liters as the base capacity across the TN70NA, TN75NA, and TN95NA configurations for the 2006-2010 model years.
  • When a cabin is fitted, the cooling system capacity rises to 12 liters, reflecting the additional volume required to circulate coolant through the cab heating circuit.
  • The 2-liter difference between the base and cabin-equipped capacity is consistent across all three variants, indicating a standardized cabin heating loop regardless of engine displacement or trim level.
  • Coolant level checks are specified at every 10 hours of operation under normal use conditions, which is a relatively short interval typical of early-hours monitoring during regular service routines.
  • The coolant change interval is set at 1,200 hours or 24 months under normal use conditions, whichever comes first, meaning time elapsed can trigger a change even before the hour threshold is reached.
  • The TN70NA, TN75NA, and TN95NA share identical coolant capacities and service intervals, meaning no variation exists in cooling system specifications across the three models within the 2006-2010 range.
