Kubota FT25 Coolant and Engine Notes
| Coolant capacity note | For service planning, the Kubota FT25 should be treated as 1.66 gal (6.3 L) coolant capacity. That is a compact tractor cooling system where a normal premixed coolant jug may cover most of the refill |
|---|---|
| Radiator capacity note | For the Kubota FT25, the captured radiator capacity is 1.59 gal (6 L). If you are doing a full drain, check the full cooling-system capacity too |
| Coolant type note | For the Kubota FT25, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant and ASTM D3306 compatible |
| Antifreeze mix note | For the Kubota FT25, 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 |
| Coolant change interval note | Coolant service for the Kubota FT25 is listed as every 700 hours. If the service history is unknown, a fresh drain and refill is usually the cleaner move |
| Engine context note | Engine context for the Kubota FT25: engine model D1503 and engine horsepower 23.3 hp (17.4 kW). Engine size helps explain why coolant capacity changes between models |
| Refill note | The practical service move for the Kubota FT25: buy enough coolant for 1.66 gal (6.3 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota FT25 Coolant Capacity FAQ
What is the Kubota FT25 coolant capacity?
The Kubota FT25 coolant capacity is listed as 1.66 gal (6.3 L) for cooling system capacity. Use this as the refill planning number and confirm the final level at the radiator or overflow bottle.
Can I use any coolant in the Kubota FT25?
No. Use ethylene glycol-based coolant and ASTM D3306 compatible or a coolant that clearly matches the manual’s required spec. Wrong coolant can create corrosion, deposits or seal problems.
Is premixed coolant okay for the Kubota FT25?
Premixed coolant can be fine if it matches ethylene glycol-based coolant and ASTM D3306 compatible and the required mix. The captured mix for the Kubota FT25 is 50/50 coolant and water mix.
How often should I change coolant in the Kubota FT25?
The captured coolant change interval for the Kubota FT25 is every 700 hours. If service history is unknown, changing it is usually smarter than guessing.
What engine specs affect Kubota FT25 coolant capacity?
The captured engine context is engine model D1503 and horsepower 23.3 hp (17.4 kW). 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.
