Lonking Wheeled loaders

Coolant capacity & service interval

Lonking wheeled loaders utilize coolant with a capacity range of 45 to 48 liters. Service intervals consist of checking every 10 hours and changing every 2000 hours or 12 months. The data covers 4 configurations.

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

Additional Notes

  • The Lonking CDM858-I carries a cooling system capacity range of 45-48 liters, whereas the CDM835-EHIII, CDM858-NGH, and CDM858-NH each specify a fixed 45-liter capacity. A capacity range rather than a fixed value typically reflects minor variation between production batches or optional equipment configurations.
  • All four wheeled loader configurations share the same 2000-hour or 12-month coolant change interval, whichever comes first. The dual-trigger format means calendar time can mandate a change even when the hour threshold has not been reached, which is common in machines with lower annual utilization.
  • The 10-hour coolant check interval applies across all four configurations under normal use conditions. A 10-hour interval corresponds roughly to daily checks in standard single-shift operation, reflecting the importance of early detection of coolant loss or contamination.
  • All four configurations are powered by the Cummins QSB6.7 engine family, though at different power ratings. The CDM835-EHIII uses the C133 variant while the CDM858 series uses the C220 variant, yet both share the same 45-liter base cooling system capacity, indicating a common cooling architecture across these power outputs.
  • A 45-liter cooling system capacity is relatively large for a wheeled loader and is consistent with the thermal management demands of a turbocharged inline-six diesel engine operating under sustained load cycles typical of loading and hauling applications.
