Bobcat Tracked loaders

Coolant capacity & service interval

Bobcat tracked loaders use coolant with a capacity range of 10,2 to 11,9 liters. Service intervals include a 10 hour check and a 24 month change. The data covers 2 configurations.

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

Type	Specifications
T140 (2005-2009)	Use: Normal Capacity 11,4 liter Capacity 11,9 liter (with 4 zone airconditioning system) Check 10 hours Change 24 months
T190, S/N 531711001 -> (2000-2003)	Use: Normal Capacity 10,2 liter Capacity 11,4 liter (with 4 zone airconditioning system) Check 10 hours Change 24 months

Additional Notes

The Bobcat T140 tracked loader (2005-2009) has a base cooling system capacity of 11.4 liters, which reflects a standard service fill for the engine and cooling circuit without auxiliary climate equipment.
When the T140 is equipped with a 4-zone air conditioning system, the cooling system capacity increases to 11.9 liters, accounting for the additional fluid volume routed through the expanded climate control circuit.
The T190 (serial number 531711001 and above, 2000-2003) carries a base cooling system capacity of 10.2 liters, which is notably lower than the T140 figure, reflecting a difference in engine displacement or cooling circuit design between the two models.
On the T190 with a 4-zone air conditioning system, the cooling system capacity rises to 11.4 liters, an increase of 1.2 liters over the base configuration to accommodate the additional circuit volume.
Both the T140 and T190 share a coolant check interval of every 10 operating hours under normal use conditions, indicating a relatively frequent monitoring requirement for a fluid system in this equipment class.
The coolant change interval for both the T140 and T190 is set at 24 months under normal use conditions, meaning the service schedule is time-based rather than tied to operating hours for the drain-and-fill service.
