Develon (Doosan) Wheeled excavators, Solar/DH

Coolant capacity & service interval

Develon (Doosan) Solar/DH wheeled excavators require coolant with a capacity range of 11,5 to 49 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 Develon (Doosan) Solar 140W-V and Solar 160W-V, both fitted with the Daewoo DB58TIS engine, share an identical cooling system capacity of 31 liters, indicating a common cooling circuit volume across these two models despite their differing size designations.
  • The Solar 180W-V and Solar 210W-V, also equipped with the Daewoo DB58TIS engine, carry a notably larger cooling system capacity of 49 liters, reflecting the greater thermal management demands of the larger machine configurations in the 2003-2007 production span.
  • A 31-liter cooling system capacity, as seen on the Solar 140W-V and Solar 160W-V, represents a substantial fill volume typical of mid-size wheeled excavator cooling circuits, where the system encompasses the engine block, cylinder head passages, radiator, and associated hoses.
  • The 49-liter capacity on the Solar 180W-V and Solar 210W-V is roughly 58 percent greater than the 31-liter figure on the smaller DB58TIS-powered models, a difference that points to a physically larger cooling circuit rather than simply a higher-displacement engine variant.
  • All four DB58TIS-powered Solar W-V models share a uniform coolant change interval of 2000 hours under normal use conditions, meaning the interval specification does not vary with cooling system capacity across the 2003-2007 range.
  • The Solar 55W-V Plus, covering the 2003-2008 model years, carries a cooling system capacity of 11.5 liters, which is the smallest value among the wheeled excavator configurations listed and is consistent with the compact class positioning of the machine.
  • The Solar 55W-V Plus also follows the same 2000-hour coolant change interval under normal use conditions as the larger DB58TIS-powered models, placing all five configurations on an identical service frequency despite the significant spread in capacity from 11.5 liters to 49 liters.
  • A 2000-hour coolant change interval, applied here under normal use conditions, is a common heavy equipment benchmark that corresponds roughly to one to two years of operation in typical construction environments, where engine load cycles and ambient conditions remain within standard parameters.
