Additional Notes

  • The John Deere 400 series cooling system capacity of 2.8 liters applies uniformly across the 425, 445, and 455 models for the 1992-2001 production span.
  • A 2.8-liter cooling system capacity is relatively modest, consistent with the compact liquid-cooled engines found in residential and light-duty lawn and garden tractors of this class.
  • The coolant check interval is set at every 10 hours of operation across all three models, reflecting a frequent visual inspection schedule rather than a full service event.
  • The coolant change interval is rated at 500 hours or 24 months under normal use conditions, meaning whichever threshold is reached first would trigger a change.
  • The 24-month time-based interval serves as a practical ceiling for low-hour machines that may not accumulate 500 hours within two years of seasonal operation.
  • All three rows carry a normal use designation, meaning the 500-hour and 24-month change intervals are not adjusted for any elevated-stress operating conditions in the available specifications.
