Additional Notes

  • The Case-IH STX 275 and STX 275 AccuSteer share a cooling system capacity of 43 liters, the smallest figure across all STX configurations listed for 2000-2005.
  • The STX 375 and STX 375 AccuSteer carry a cooling system capacity of 47 liters, placing them between the base STX 275 and the heavier STX 375 variants.
  • The STX 375 Heavy Duty shows a notably larger cooling system capacity of 80.3 liters compared to the standard STX 375 at 47 liters, a difference of over 33 liters that reflects the greater thermal demands of the heavy-duty configuration.
  • The STX 375 QUADTRAC, STX 440, and STX 440 QUADTRAC all share the same 80.3-liter cooling system capacity as the STX 375 Heavy Duty, indicating a common cooling architecture across those higher-output and track-drive configurations.
  • A 10-hour check interval applies to all six configurations across the 2000-2005 model range. In large agricultural equipment, a 10-hour interval typically aligns with daily or near-daily inspection routines during active field seasons.
  • All configurations specify a 24-month coolant change interval under normal use conditions. A time-based interval rather than an hours-based one is common for coolant, as chemical degradation of corrosion inhibitors occurs over time regardless of engine operating hours.
