Kubota L4400 Coolant and Engine Notes
| Coolant capacity note | The Kubota L4400’s key coolant figure here is 1.73 gal (6.5 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Radiator capacity note | Radiator capacity is listed as 1.73 gal (6.5 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 L4400 is ethylene glycol-based coolant and ASTM D3306 compatible. 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 L4400 coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Engine context note | The Kubota L4400 engine data captured here is engine horsepower 45.3 hp (33.8 kW) and displacement 2.2 L (134.5 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | For a coolant change on the Kubota L4400, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
Kubota L4400 Coolant Capacity FAQ
How much coolant does the Kubota L4400 take?
The main coolant amount captured for the Kubota L4400 is 1.73 gal (6.5 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 L4400?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota L4400, the captured coolant type is ethylene glycol-based coolant and ASTM D3306 compatible.
What antifreeze mix does the Kubota L4400 use?
The captured antifreeze mix for the Kubota L4400 is 50/50 coolant and 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 L4400 coolant be replaced?
Use the service interval in the operator manual as the service guide. Coolant can look okay but still lose corrosion protection over time.
Why does the Kubota L4400 coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota L4400, the supporting engine data is horsepower 45.3 hp (33.8 kW) and displacement 2.2 L (134.5 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.
