Caterpillar Wheeled tool carriers

Coolant capacity & service interval

Caterpillar wheeled tool carriers require coolant with a capacity of 42 liters. Service intervals include checks every 10 hours and changes at 36 months/3000 hours or 72 months/12000 hours. The data covers 2 configurations.

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

TypeSpecifications
IT-62H, M5G (2007- )
  • Use: Preferred, extended
  • Capacity 42 liter
  • Check 10 hours
  • Change 72 months/ 12000 hours
IT-62H, M5G (2007- )
  • Use: Alternative (acceptable)
  • Capacity 42 liter
  • Check 10 hours
  • Change 36 months/ 3000 hours

Additional Notes

  • The IT-62H with M5G engine, introduced in 2007, carries a cooling system capacity of 42 liters, a figure that reflects a full system fill inclusive of the engine block, radiator, and associated plumbing rather than a partial or component-only service volume.
  • A check interval of 10 hours applies to the cooling system regardless of which fluid type is in use, meaning both the preferred extended and alternative acceptable coolant configurations share the same inspection frequency.
  • When the preferred, extended coolant is used in the Caterpillar IT-62H M5G cooling system, the change interval extends to 72 months or 12,000 hours, whichever comes first, representing a significantly longer service life than the alternative fluid allows.
  • The alternative acceptable coolant in the same 42-liter cooling system carries a change interval of 36 months or 3,000 hours, which is half the calendar duration and one quarter of the hour-based interval associated with the preferred extended fluid.
  • The 3,000-hour change threshold tied to the alternative acceptable coolant is notably lower than the 12,000-hour threshold of the preferred extended fluid, a difference of 9,000 hours that has direct implications for service frequency over the working life of the machine.
