Manitowoc Excavators & lift cranes

Coolant capacity & service interval

Manitowoc excavators and lift cranes require coolant with a capacity range of 49 to 98 liters. The data covers 6 configurations.

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

Additional Notes

  • The Manitowoc 2250 fitted with the Cummins N14 engine carries the largest cooling system capacity in the lineup at 98 liters, reflecting the substantial thermal management demands of a large-displacement inline-six engine in heavy crane service.
  • The Manitowoc 555 shares a 49-liter cooling system capacity across both the Cummins K19 and Cummins QSC8.3 engine options, indicating that despite differences in engine architecture between the two powerplants, the cooling circuit volume remains consistent for that model.
  • The Manitowoc 777 similarly shows a consistent cooling capacity of 57 liters across both the Cummins 6CTA8.3 and Cummins MTA11 configurations, a figure that falls between the 555 and 999 models in the range.
  • The Manitowoc 999 cooling system holds 74 liters, placing it between the 777 and the 2250 in total coolant volume, which corresponds to a mid-to-large class of crane requiring proportionally greater heat dissipation capacity.
  • All six configurations carry a normal use condition designation, meaning the specified capacities apply to standard operating environments rather than severe-duty cycles that might otherwise alter service fill requirements.
  • The capacity values listed across all rows represent cooling system fills rather than engine-block-only volumes, as crane cooling systems at this scale incorporate radiators, hoses, and reservoir circuits that collectively account for the full stated figures.
