Hyundai Wheeled excavators, HW

Coolant capacity & service interval

Hyundai HW wheeled excavators utilize coolant with capacities ranging from 19,5 to 40 liters. Service intervals include checks every 10 hours and changes every 2000 hours or 24 months. The data covers 5 configurations.

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

Additional Notes

  • The Hyundai HW140, HW150A CR, HW160, and HW180 all share a 19.5-liter cooling system capacity, while the HW210 requires a notably larger 40-liter fill, reflecting the greater thermal demands of a higher-output machine in the same wheeled excavator family.
  • The HW210 with Cummins QSB 6.7 Tier 4f carries a cooling system capacity more than double that of the smaller models, a difference that has direct implications for coolant procurement and the time required to perform a full drain-and-fill service.
  • Across all five configurations, the coolant change interval is set at 2000 hours or 24 months under normal use conditions, whichever comes first. The dual-trigger format means calendar time can mandate a change even when machine hours remain low.
  • The 10-hour coolant check interval applies uniformly across all listed models and years. In heavy equipment operation, a 10-hour cycle typically corresponds to daily checks, making coolant level inspection a routine daily task rather than a periodic one.
  • The HW140, HW160, and HW180 models with Cummins QSB 6.7 Tier 4f engines share an identical 19.5-liter capacity and the same check and change intervals, indicating a common cooling system architecture across those three variants for the 2016-2021 period.
  • The HW150A CR with Stage V engine, introduced from 2022, carries the same 19.5-liter cooling system capacity and identical service intervals as the earlier Tier 4f models in the lighter weight classes, despite the transition to a newer emissions standard.
