Bobcat Utility vehicles

Coolant capacity & service interval

Bobcat Utility vehicles require coolant with a capacity range of 3,5 to 7,8 liters. Service intervals include checking every 10 hours and changing every 100 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 2200D, 2200S, and 2300 models, each equipped with the Kubota D722 engine, share an identical cooling system capacity of 7.8 liters, indicating a consistent system volume across all three configurations.
  • A 7.8-liter cooling system capacity is relatively large for a compact utility vehicle engine, reflecting the total volume of coolant held across the radiator, engine block, and associated passages during a full service fill.
  • The Kubota D722-equipped models specify a coolant check interval of every 10 hours, which represents one of the more frequent inspection points in a typical service schedule and reflects the importance of monitoring coolant level during early or regular operation.
  • The change interval for the 2200D, 2200S, and 2300 cooling systems is set at 100 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would trigger a service event.
  • The Bobcat 3400D, fitted with the Yanmar 3TNM72-APL engine, carries a cooling system capacity of 3.5 liters, which is notably smaller than the 7.8-liter figure associated with the Kubota D722-powered models.
  • The 3.5-liter capacity of the 3400D cooling system reflects the smaller displacement and physical size of the Yanmar 3TNM72-APL engine relative to the Kubota D722 installations in the other listed models.
