Hidromek Wheeled excavators

Coolant capacity & service interval

Hidromek wheeled excavators use coolant with a capacity range of 24 to 29,3 liters. Service intervals consist of a 10 hour check and a 2000 hour change. The data covers 3 configurations.

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

Additional Notes

  • The Hidromek wheeled excavators cooling system capacity varies by model, with the HMK 140W and HMK 150W each holding 24 liters, while the HMK 200W holds 29.3 liters.
  • The 29.3-liter cooling system capacity on the HMK 200W reflects a larger engine displacement relative to the 140W and 150W models, which require proportionally less coolant volume at 24 liters each.
  • All three models share a 10-hour coolant check interval, which is a very short cycle consistent with routine operational inspections rather than a fluid service event.
  • The coolant change interval across all three models is set at 2000 hours under normal use conditions, a figure that applies to standard operating environments rather than demanding or severe duty cycles.
  • The HMK 140W and HMK 150W share identical cooling system specifications in both capacity and service intervals, indicating a common cooling architecture between the two models despite their different designations.
