Kubota B2201 Coolant and Engine Notes
| Coolant capacity note | The headline cooling-system number for the Kubota B2201 is 1.74 gal (6.6 L). Buy enough coolant before opening the drain plug |
|---|---|
| Radiator capacity note | For the Kubota B2201, the captured radiator capacity is 1.65 gal (6.2 L). If you are doing a full drain, check the full cooling-system capacity too |
| Coolant type note | Coolant type for the Kubota B2201 is listed as ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas |
| Antifreeze mix note | For the Kubota B2201, the captured mix is 50/50 coolant and water mix. Straight water is not the right long-term answer unless you are only flushing the system |
| Engine context note | Engine context for the Kubota B2201: engine horsepower 19.7 hp (14.7 kW) and displacement 1.1 L (68.5 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | When refilling the Kubota B2201, use 1.74 gal (6.6 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
Kubota B2201 Coolant Capacity FAQ
What is the Kubota B2201 coolant capacity?
