Kubota L305 Coolant and Engine Notes
| Coolant capacity note | The headline cooling-system number for the Kubota L305 is 1.59 gal (6 L). Buy enough coolant before opening the drain plug |
|---|---|
| Radiator capacity note | Radiator capacity is listed as 1.59 gal (6 L). The full cooling system can be higher because coolant also sits in the engine and hoses |
| Coolant type note | The captured coolant type for the Kubota L305 is ethylene glycol-based coolant and Kubota Genuine Coolant. Do not mix unknown coolant types unless the label and manual say they are compatible |
| Antifreeze mix note | The 50/50 coolant and water mix mix gives the Kubota L305 coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Coolant change interval note | The captured coolant change interval for the Kubota L305 is every 700 hours. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Kubota L305 engine data captured here is engine horsepower 30 hp (22.4 kW) and displacement 1.3 L (80.7 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | For a coolant change on the Kubota L305, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
