Kubota GL25 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GL25, 1.59 gal (6 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 GL25 radiator figure is 1.59 gal (6 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | Use the right coolant formula for the Kubota GL25: ethylene glycol-based coolant and ASTM D3306 compatible. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | The Kubota GL25 antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Coolant change interval note | For the Kubota GL25, the service interval is listed as every 700 hours. Time matters too, not just engine hours |
| Engine context note | For the Kubota GL25, the supporting engine specs are engine model D1463, engine horsepower 24.7 hp (18.4 kW), and displacement 1.5 L (91.5 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota GL25, plan around 1.59 gal (6 L) and confirm the final level after air works out of the system |
Kubota GL25 Coolant Capacity FAQ
What is the Kubota GL25 coolant capacity?
The Kubota GL25 coolant capacity is listed as 1.59 gal (6 L) for coolant 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 GL25?
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 GL25?
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 GL25 is 50/50 coolant and water mix.
How often should I change coolant in the Kubota GL25?
The captured coolant change interval for the Kubota GL25 is every 700 hours. If service history is unknown, changing it is usually smarter than guessing.
What engine specs affect Kubota GL25 coolant capacity?
The captured engine context is engine model D1463, horsepower 24.7 hp (18.4 kW), and displacement 1.5 L (91.5 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.
