Atlas GmbH Wheeled excavators

Coolant capacity & service interval

Atlas GmbH Wheeled excavators require coolant with a capacity range of 16,5 to 42 liters. Service intervals include checks at 100 and 500 hours, with a change interval of 2000 hours. The data covers 6 configurations.

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

Additional Notes

  • Across the Atlas GmbH wheeled excavator lineup for 2010-2014, cooling system checks are scheduled at every 100 hours of operation under normal use conditions, while coolant changes are set at 2000 hours regardless of machine size.
  • The 140W and 150W share an identical cooling system capacity of 35 liters, indicating a common engine cooling architecture between the two models for the 2010-2014 period.
  • The 160W carries a 38-liter cooling system capacity, placing it between the smaller 35-liter 140W/150W group and the larger 42-liter machines, which reflects the stepped increase in engine displacement and thermal load across the range.
  • The 190W and 220W both specify a 42-liter cooling system capacity under normal use, suggesting a shared engine or cooling circuit configuration despite the difference in model designation.
  • The 1604MK differs from the 2010-2014 models in both its check interval and use condition. A 500-hour check interval under a flexible (max) use condition contrasts with the 100-hour check intervals specified for the normal-use 2010-2014 machines.
  • The 1604MK cooling system capacity of 16.5 liters is notably lower than all 2010-2014 models in the dataset, which range from 35 to 42 liters, consistent with a smaller or differently configured machine class.
  • A 2000-hour coolant change interval is a common heavy equipment standard, typically aligned with major service cycles and intended to maintain corrosion inhibitor effectiveness and coolant pH over extended operating periods.
