IMT All models

Coolant capacity & service interval

IMT All models use coolant with a capacity range of 8,5 to 17,5 liters. Service intervals include checks at 10 hours and changes at 800 hours, 1000 hours, or 12 months. The data covers 10 configurations.

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

Additional Notes

  • The IMT 539 (1983-1996) carries a cooling system capacity of 8.5 liters, which is notably smaller than the 10-liter figure shared by the 540 through 569 model range, reflecting a difference in engine displacement or cooling circuit size between these configurations.
  • The IMT 577 and 577 DV (1983-1996) hold the largest cooling system capacity in the lineup at 17.5 liters, nearly double the 10-liter figure of the mid-range models, indicating a substantially larger engine and cooling circuit consistent with higher-output tractor applications.
  • The 539 and the 577/577 DV share a 10-hour coolant check interval under normal use conditions, a short-cycle inspection point that reflects the operational demands of agricultural machinery where cooling system integrity is monitored frequently between longer service events.
  • The 539 specifies a change interval of 1,000 hours or 12 months under normal use, whichever comes first. The dual-condition format means calendar time can trigger a change even when hour accumulation is low, as is common in seasonal or low-utilization working patterns.
  • The 577 and 577 DV carry a change interval of 1,000 hours with no accompanying calendar-month condition listed, distinguishing the interval structure of the largest-capacity model from the time-plus-hours format applied to the 539.
  • Models 540 through 569, spanning the 1986-1996 production period, all share an 800-hour or 12-month change interval under normal use. The 800-hour threshold is shorter than the 1,000-hour interval on the 539 and 577 series, placing more frequent coolant renewal requirements on the mid-range models.
  • The 10-liter capacity is consistent across a wide range of variants including standard, De Luxe, and DV configurations within the 540-569 group, indicating that trim level and dual-variant (DV) designations do not alter the cooling system volume for those models.
  • No coolant check interval is listed for the 540 through 569 models, whereas the 539 and 577/577 DV both specify a 10-hour check. The presence of a dedicated check interval on those two models points to a more closely monitored cooling maintenance schedule relative to the mid-range group.
