IHI Crawler carrier

Coolant capacity & service interval

IHI Crawler carrier coolant capacity ranges from 7,8 to 24,5 liters. Service intervals include checks every 10 hours and changes every 24 months. The data covers 3 configurations.

Additional Notes

  • The IHI Crawler carrier cooling system capacities vary considerably across engine configurations, ranging from 7.8 liters on the IC35 with Kubota V2403-M up to 24.5 liters on the IC70-2 with Mitsubishi 6D16-TLU2B, reflecting the significant difference in engine displacement and thermal output between the smallest and largest models in the lineup.
  • The IC50 paired with the Isuzu 4JJ1 engine carries a cooling system capacity of 16.4 liters, positioning it between the IC35 and IC70-2 and indicating a mid-range thermal management requirement consistent with a larger four-cylinder turbodiesel.
  • A 24.5-liter cooling system capacity on the IC70-2 is a substantial volume, typical of a six-cylinder heavy-duty diesel engine where maintaining stable operating temperatures across extended work cycles demands a larger coolant reservoir.
  • All three configurations share a 10-hour coolant level check interval under normal use conditions, a frequency associated with machines operating in demanding environments where coolant loss through minor seepage or evaporation warrants frequent monitoring.
  • The coolant change interval is set at 24 months across all three configurations under normal use conditions, a time-based interval rather than an hours-based one, which reflects the degradation of coolant additives over time regardless of machine operating hours.
  • The consistent 24-month change interval across the IC35, IC50, and IC70-2 under normal use conditions applies regardless of the notable differences in system capacity between the three, meaning the service frequency is driven by fluid chemistry rather than volume.
