Additional Notes

  • The John Deere 3025D carries a cooling system capacity of 5 liters, while the 3035D and 3043D each hold 5.5 liters, reflecting a modest but measurable difference tied to the larger engine displacements in the higher models.
  • A coolant check interval of 10 hours applies across all three models, placing routine inspection among the most frequent maintenance tasks in the service schedule.
  • The coolant change interval is set at 2000 hours or 24 months, whichever comes first, meaning calendar time can trigger a change even when the hour threshold has not been reached.
  • The 2000-hour mark represents a substantial service life between coolant changes, consistent with heavy-duty tractor use where extended drain intervals reduce downtime in working conditions.
  • All three models share the same change interval of 2000 hours or 24 months under normal use conditions, despite the capacity difference between the 3025D and the two larger variants.
