Kubota STV

Coolant capacity & service interval

Kubota STV uses coolant with a capacity of 6.1 liters. The service interval for coolant change is 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Kubota STV32, STV36, and STV40 each share an identical cooling system capacity of 6.1 liters, indicating a common engine cooling architecture across all three variants introduced in 2004.
  • A 6.1-liter cooling system capacity is a relatively substantial figure for a compact utility tractor, reflecting the volume of coolant required to fill the radiator, engine block passages, and associated hoses collectively.
  • The coolant change interval is set at 24 months across all three models under normal use conditions, meaning a calendar-based schedule governs service rather than an hour-meter reading.
  • The uniform 24-month interval across the STV32, STV36, and STV40 under normal use conditions means no model-specific variation exists in how frequently the cooling system fluid is renewed.
