Caterpillar Scrapers

Coolant capacity & service interval

Caterpillar Scrapers use coolant with capacities ranging from 38 to 107 liters. Service intervals include checks at 10 hours and 6 months/1000 hours, and changes at 24 months/3000 hours, 36 months/3000 hours, and 72 months/6000 hours. The data covers 16 configurations.

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

Additional Notes

  • The Caterpillar 613C Series II (93X) cooling system holds 38 liters, a notably smaller capacity than the 623F and 623G models in the same scraper range, reflecting the difference in engine and machine size between the two model classes.
  • The 623F (5EW and 6BK) cooling system capacity is 83 liters under normal use conditions, with a change interval of 24 months or 3,000 hours, whichever comes first.
  • When the preferred, extended use condition applies to the 623F (5EW and 6BK), the same 83-liter cooling system capacity is retained, but the change interval extends to 72 months or 6,000 hours, doubling both the time and hour thresholds compared to normal use.
  • The 623G ARW serial prefix cooling system holds 107 liters, the largest capacity among all configurations listed here, and carries a normal-use change interval of 36 months or 3,000 hours.
  • The 623G CES and DBC serial prefix configurations share a 73-liter cooling system capacity, which sits between the 623F and the 623G ARW figures, and both follow the same 36-month or 3,000-hour normal-use change interval.
  • Across all 623G configurations, the preferred, extended use condition aligns the change interval to 72 months or 6,000 hours, matching the extended interval available for the 623F and the 613C Series II under their respective conditions.
  • The 613C Series II (93X) is listed only under a single change interval of 72 months or 6,000 hours with no separate normal-use interval, placing it directly in line with the extended-use intervals of the larger models without a shorter alternative.
  • Wheel cooling on the 623F (5EW and 6BK) and all 623G configurations is specified at 45 liters per wheel, with a check interval of 6 months or 1,000 hours. The per-wheel designation means total wheel cooling fluid across a machine with multiple driven wheels would exceed this figure significantly.
  • All cooling system entries across every model and configuration share a 10-hour check interval, indicating that coolant level verification is treated as a frequent routine task regardless of machine size or serial prefix.
  • The shift from a 24-month to a 36-month normal-use change interval between the 623F (1993-2001) and the 623G (2000- ) models represents a meaningful difference in baseline service scheduling between the two generations under standard operating conditions.
