Additional Notes

  • The Deutz-Fahr Series 4 E Keyline cooling system capacity differs between the 4046 and the rest of the lineup, with the 4046 E Keyline holding 5 liters compared to the 12 liters shared by the 4050, 4055, and 4060 E Keyline variants.
  • A 12-liter cooling system capacity, as seen in the 4050, 4055, and 4060 E Keyline, is consistent with larger engine displacements that generate more heat and require a greater volume of coolant to maintain stable operating temperatures.
  • The 5-liter capacity of the 4046 E Keyline reflects a smaller engine configuration, where a reduced coolant volume is sufficient for the thermal management demands of that particular power unit.
  • All four variants share a coolant check interval of every 10 hours of operation under normal use conditions, indicating a relatively frequent visual or level inspection requirement early in the service cycle.
  • The coolant change interval across all four variants is set at 1200 hours or 24 months under normal use conditions, whichever comes first, meaning calendar time can trigger a change even when the hour threshold has not been reached.
  • A 24-month calendar limit on coolant changes is standard practice for extended-life coolants, as certain additive packages degrade over time regardless of engine operating hours.
  • The uniform change interval of 1200 hours and 24 months across the 4046, 4050, 4055, and 4060 E Keyline variants applies despite the notable difference in system capacity between the 4046 and the other three models.
