Kubota B1502 Coolant and Engine Notes
| Coolant capacity note | The Kubota B1502’s key coolant figure here is 1.65 gal (6.2 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Radiator capacity note | For the Kubota B1502, 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 | Use the right coolant formula for the Kubota B1502: ethylene glycol-based coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | For the Kubota B1502, 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 B1502: engine model D850, engine horsepower 15 hp (11.2 kW), and displacement 0.9 L (54.9 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota B1502, plan around 1.65 gal (6.2 L) and confirm the final level after air works out of the system |
Kubota B1502 Coolant Capacity FAQ
What is the cooling system capacity of the Kubota B1502?
The Kubota B1502 cooling system capacity is shown as 1.65 gal (6.2 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota B1502?
Use ethylene glycol-based coolant. The blunt rule is simple: match the manual’s coolant spec and do not mix unknown coolant formulas.
Should I use straight water in the Kubota B1502?
Not for normal long-term use. The Kubota B1502 should use 50/50 coolant and water mix or the manual’s specified coolant mix so the system gets corrosion, freeze and boil protection.
Does old coolant matter in the Kubota B1502?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota B1502 is the service interval in the operator manual.
Why does the Kubota B1502 coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota B1502, the supporting engine data is engine model D850, horsepower 15 hp (11.2 kW), and displacement 0.9 L (54.9 cu in).
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.
