Kubota B2401 Coolant and Engine Notes
| Coolant capacity note | For the Kubota B2401, 1 gal (3.8 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Radiator capacity note | The Kubota B2401 radiator figure is 1 gal (3.8 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | For the Kubota B2401, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant |
| Antifreeze mix note | The Kubota B2401 antifreeze mix is listed as 50/50 coolant and distilled water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Coolant change interval note | For the Kubota B2401, the service interval is listed as every 700 hours. Time matters too, not just engine hours |
| Engine context note | For the Kubota B2401, the supporting engine specs are engine model D1105, engine horsepower 21.9 hp (16.3 kW), and displacement 1.1 L (68.5 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | The practical service move for the Kubota B2401: buy enough coolant for 1 gal (3.8 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota B2401 Coolant Capacity FAQ
How much coolant does the Kubota B2401 take?
The main coolant amount captured for the Kubota B2401 is 1 gal (3.8 L). Buy a little extra so you can top up after the engine warms up and cools down.
Does coolant type matter on the Kubota B2401?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota B2401, the captured coolant type is ethylene glycol-based coolant.
What antifreeze mix does the Kubota B2401 use?
The captured antifreeze mix for the Kubota B2401 is 50/50 coolant and distilled water mix. A 50/50-style mix is the common practical answer unless your manual or climate calls for something different.
When should the Kubota B2401 coolant be replaced?
Use every 700 hours as the service guide. Coolant can look okay but still lose corrosion protection over time.
What engine specs affect Kubota B2401 coolant capacity?
The captured engine context is engine model D1105, horsepower 21.9 hp (16.3 kW), and displacement 1.1 L (68.5 cu in). Engine size is one reason coolant capacity changes between tractors.
Mistakes do happen. Tractor coolant specs can change by year, market, engine, radiator, cab/heater setup and service procedure. Please check the operator manual, decal information and official kubotausa.com website for official information before draining or refilling the cooling system.
