Landini Series 6C

Coolant capacity & service interval

Landini Series 6C requires coolant with a capacity of 25 liters. Service intervals occur every 2000 hours or 24 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Every configuration in the Landini Series 6C covered by these specifications carries an identical cooling system capacity of 25 liters, regardless of model designation or emission tier.
  • A 25-liter cooling system capacity is relatively large for an agricultural tractor, reflecting the thermal demands of high-output six-cylinder engines operating under sustained load conditions.
  • The Series 6C lineup splits across two distinct emission standards: the earlier T4i / Tier IIIB variants span 2014-2017, while the later Tier 4f variants span 2017-2021.
  • Tier 4f (Final) represents a stricter emissions standard than Tier IIIB, typically requiring additional aftertreatment components such as selective catalytic reduction systems, which can influence overall cooling system design and load.
  • The coolant change interval is specified at 2000 hours or 24 months under normal use conditions, meaning whichever threshold is reached first would govern the service event.
  • A 2000-hour interval for coolant replacement is consistent with extended-life coolant formulations, which are engineered to maintain corrosion inhibitor effectiveness and thermal stability over long service periods in heavy equipment.
  • The 24-month calendar limit within the change interval acknowledges that coolant degrades over time even when hour accumulation is low, such as in seasonal or low-utilization operation.
  • The T4i / IIIB models — the 6-120C, 6-130C, and 6-140C — share the same 25-liter capacity and 2000-hour/24-month interval as their Tier 4f successors, the 6-125C, 6-135C, and 6-145C, indicating no cooling system service changes accompanied the emissions tier transition.
