Bobcat Wheeled loaders

Coolant capacity & service interval

Bobcat wheeled loaders use coolant with a capacity range of 9 to 16,3 liters. Service intervals include checks every 10 hours and changes every 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 A300 Turbo wheeled loader, covering model years 2002-2010, carries a cooling system capacity of 16.3 liters, which represents the total system fill volume including the engine block, radiator, and associated passages.
  • The A770 fitted with the Kubota V3800-DI-T-E engine lists two distinct capacity values: 15.1 liters with a heater installed and 14.4 liters without one, reflecting how the heater core adds measurable volume to the coolant circuit.
  • Across the AL275, AL350, and AL440 models spanning 2005-2010, the cooling system capacity is uniformly 9 liters, a notably lower figure compared to the A300 Turbo and A770 configurations.
  • The A300 Turbo's 16.3-liter capacity is the largest among the listed Bobcat wheeled loaders, while the AL-series models at 9 liters each represent the smallest cooling system volumes in the dataset.
  • All five configurations share an identical coolant check interval of 10 hours, placing cooling system inspection among the most frequent maintenance tasks in the service schedule.
  • A 24-month change interval applies uniformly across all listed models and year ranges under normal use conditions, meaning coolant replacement is time-based rather than tied to machine hours for these configurations.
  • The AL275, AL350, and AL440 share not only the same 9-liter capacity but also the same check and change intervals, indicating a common cooling system architecture across the AL-series lineup for the 2005-2010 period.
