Ford TF

Coolant capacity & service interval

Ford TF uses coolant with a capacity range of 37 to 39 liters. Service intervals include checking at 10 hours and changing at 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 Ford TF 42 and TF 44 share an identical cooling system capacity of 37 liters, while the TF 46 carries a slightly larger 39-liter capacity, reflecting a difference of 2 liters across the model range.
  • A 37-liter cooling system capacity, as seen on the TF 42 and TF 44, represents a substantial volume consistent with heavy-duty or industrial engine applications where thermal management demands are high.
  • The TF 46 cooling system capacity of 39 liters similarly falls within the range typical of large-displacement or high-output engines requiring greater coolant volume to maintain stable operating temperatures.
  • All three configurations share a coolant check interval of every 10 hours of operation under normal use conditions, indicating a frequent monitoring requirement relative to the change interval.
  • The coolant change interval across all three configurations is set at 1200 hours or 24 months under normal use conditions, whichever comes first, combining both an operational hour threshold and a calendar-based limit.
  • A 24-month calendar interval running alongside the 1200-hour threshold means that in lower-utilization applications, time elapsed rather than engine hours would govern when a coolant change is due.
  • The TF 46 carries a starting year of 1986, placing its introduction three years after the TF 42 and TF 44, which both date from 1983, and the TF 46 also carries the only capacity figure in the range that differs from the other two models.
