Etec Wheeled loaders

Coolant capacity & service interval

Etec wheeled loaders use coolant with a capacity range of 40 to 60 liters. The service interval for coolant is 2000 hours. The data covers 5 configurations.

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

Additional Notes

  • The Etec Wheeled Loaders cooling system capacities range from 40 liters on the 2020-II model up to 60 liters on the 2050-II, reflecting the differing displacement and thermal output of each engine configuration.
  • The 2020-II with the Doosan DL06 engine holds 40 liters of coolant, while the 2025-II fitted with the same DL06 engine holds 45 liters, indicating a larger cooling circuit despite sharing the same engine family.
  • Both the 2030-II with the Doosan DL08 and the 2040-II with the Cummins QSL9 share a 50-liter cooling system capacity, even though the two machines use engines from different manufacturers.
  • The 2050-II paired with the Cummins QSM11 carries the largest cooling system capacity in the lineup at 60 liters, consistent with the QSM11 being a higher-displacement engine relative to the QSL9.
  • All five configurations share a uniform coolant change interval of 2000 hours under normal use conditions, meaning no model in the range calls for an accelerated or extended service schedule relative to the others.
  • A 2000-hour coolant change interval under normal use is a common heavy-equipment standard, generally corresponding to roughly one to two years of operation depending on annual machine utilization.
  • All specifications are designated for normal use conditions, meaning none of the listed intervals are adjusted for severe-duty operation such as extreme ambient temperatures or continuous high-load cycles.
