Additional Notes

  • The Massey Ferguson MF 6S cooling system capacity is 26 liters across all listed configurations, spanning the 135, 145, 155, 165, and 180 power variants. A 26-liter figure is consistent with a full cooling system service fill on a mid-to-large agricultural tractor, encompassing the engine block, cylinder head passages, radiator, and associated hoses rather than a partial drain-and-refill volume.
  • The coolant change interval is set at 1200 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format, combining an engine hours threshold with a calendar period, reflects the reality that coolant degrades both through thermal cycling during operation and through chemical breakdown over time, even when hours accumulate slowly.
  • All ten configurations share an identical 26-liter capacity and 1200-hour/24-month interval regardless of transmission type. The Dyna-6 is a six-step powershift transmission, while the Dyna-VT is a continuously variable transmission, yet neither difference influences the cooling system specifications listed here.
  • The power variants in the MF 6S range covered by these specifications run from 135 to 180 horsepower. Despite that span of engine output, the cooling system capacity remains uniform at 26 liters across all five power levels, indicating a shared engine architecture and cooling circuit design across the range.
  • Dyna-VT variants are listed for the 2021-2022 period, while Dyna-6 variants carry a 2022 start year. Both transmission types share the same 26-liter capacity and 1200-hour/24-month service interval, so the difference in introduction timing has no bearing on the coolant service schedule.
