Additional Notes

  • The cooling system capacity across the 938 Vario MT (T-T9BA), 940 Vario MT (T-T9BC), and 940 Vario MT (T-T9BE) is identical at 42.2 liters, indicating a shared cooling system architecture among these three configurations.
  • A 42.2-liter cooling system capacity is consistent with large-displacement agricultural powertrains, where high thermal loads from sustained field operation demand substantial coolant volume to maintain stable engine temperatures.
  • The coolant check interval is set at 10 hours across all three configurations, reflecting the frequency typical of early operational monitoring in heavy-duty machinery where coolant level and condition can shift quickly under load.
  • The coolant change interval is specified at 2000 hours or 24 months, whichever comes first, applying a dual threshold that accounts for both operational intensity and time-based fluid degradation regardless of machine usage levels.
  • The 24-month time-based threshold in the change interval means a machine with low annual hours would still require a coolant change within two years, as coolant additives degrade over time independent of engine runtime.
  • All three configurations share the same check and change intervals, meaning the T-T9BA, T-T9BC, and T-T9BE variants follow a uniform coolant service schedule despite carrying different model designations.
