New Holland TND/S

Coolant capacity & service interval

New Holland TND/S 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 TND/S cooling system capacity is listed at two distinct values: 10 liters as the base figure and 12 liters when the cabin heating circuit is included.
  • The 2-liter difference between the base and cabin-equipped capacity reflects the additional coolant volume routed through the cab heater core and associated plumbing.
  • All three variants, the TN 55 D/S, TN 65 D/S, and TN 75 D/S, share identical cooling system capacities across the 1998-2003 production span, indicating a common cooling architecture regardless of engine output rating.
  • A coolant level check interval of 10 hours is specified under normal use conditions, placing routine inspection among the most frequent maintenance tasks in the service schedule.
  • The coolant change interval is set at 1200 hours or 24 months under normal use, meaning whichever threshold is reached first would govern the service event in practice.
  • A 24-month calendar limit alongside the 1200-hour threshold acknowledges that low-utilization machines may degrade coolant through age-related chemical breakdown before accumulating sufficient operating hours.
