Volvo Compact tracked loaders, MCT

Coolant capacity & service interval

Volvo Compact tracked loaders, MCT use coolant with a capacity of 22 liter. Service intervals include checks at 10 hours and changes at 2000 hours or 6000 hours. The data covers 5 configurations.

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

Additional Notes

  • All five configurations across the MCT compact tracked loader range share a uniform cooling system capacity of 22 liters, indicating a consistent engine cooling architecture across both the C-series and D-series generations within the 2013-2019 span.
  • The 22-liter figure represents a full cooling system fill, encompassing the engine block, cylinder head passages, radiator, and associated hoses rather than a partial or top-up volume.
  • Volvo MCT110D, MCT125D, and MCT135D units from 2017-2019 carry a coolant change interval of 2000 hours under normal use conditions, a notably shorter service cycle compared to the C-series models covered in the same specifications.
  • The MCT125C (2013-2017) and MCT145C (2013-2017) both specify a 6000-hour coolant change interval under normal use, a figure three times longer than the 2000-hour interval assigned to the D-series counterparts.
  • A 6000-hour coolant change interval is associated with extended-life coolant formulations, which use organic acid technology (OAT) or similar chemistry to resist silicate depletion over longer service periods.
  • The D-series specifications include a coolant level check at every 10 hours of operation under normal use conditions, a routine inspection interval absent from the C-series rows in the same specification set.
  • A 10-hour check interval corresponds roughly to a daily or every-other-day inspection cycle on a machine running a standard single shift, making low-coolant conditions detectable before significant engine thermal damage can occur.
  • The transition from C-series to D-series models within the MCT range coincides with a reduction in the coolant change interval from 6000 hours to 2000 hours, reflecting a difference in the coolant service life requirements between the two generations.
