New Holland TL

Coolant capacity & service interval

New Holland TL models require 14 liters of coolant. Service intervals include checking every 10 hours and changing every 2400 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The New Holland TL series cooling system capacity is 14 liters across all four variants — the TL 70, TL 80, TL 90, and TL 100 — for the 1998-2001 model years.
  • A uniform 14-liter capacity across the TL 70, TL 80, TL 90, and TL 100 indicates a shared cooling system architecture despite the differing engine output levels each model designation implies.
  • The coolant check interval is set at every 10 hours of operation under normal use conditions, which reflects the frequency typical of early operational monitoring in agricultural equipment.
  • The coolant change interval is specified at 2400 hours or 12 months, whichever comes first, under normal use conditions across all four TL variants in the 1998-2001 range.
  • A 2400-hour change interval is a relatively extended service cycle, consistent with heavy-duty agricultural machinery where operational hours accumulate over long working seasons rather than daily commuting patterns.
  • The combination of an hour-based and calendar-based change interval — 2400 hours or 12 months — accounts for machines that may sit idle for extended periods without accumulating sufficient operating hours to trigger a time-based service need.
