Antonio Carraro Supertrac HTM series (35)

Coolant capacity & service interval

Antonio Carraro Supertrac HTM series (35) uses coolant with a capacity of 12 liters. Service intervals include checking at 50 hours and changing at 2000 hours or 24 months. The data covers 4 configurations.

Additional Notes

  • The Antonio Carraro Supertrac HTM series carries a cooling system capacity of 12 liters across all four variants — the HTM 5400, HTM 5600, HTM 7700, and HTM 8400. A 12-liter figure is consistent with a mid-range agricultural tractor cooling circuit, accounting for the radiator, engine block passages, and associated hoses.
  • All four HTM variants share an identical check interval of every 50 hours under normal use conditions. In tractor operation, a 50-hour coolant check interval is a relatively short cycle, reflecting the thermal demands placed on cooling systems in field environments.
  • The coolant change interval is rated at 2000 hours or 24 months, whichever comes first, across the HTM 5400, HTM 5600, HTM 7700, and HTM 8400. The dual threshold — hours and calendar time — means a machine with low annual usage would still require a coolant change at the 24-month mark regardless of accumulated hours.
  • No variation in cooling system capacity or service intervals exists between the four HTM variants introduced from 1998. Despite differences in model designation — which typically reflect engine output or configuration differences — the 12-liter capacity and the 50-hour check and 2000-hour/24-month change schedule are uniform across the range.
