Kubota L4701 Coolant and Engine Notes
| Coolant capacity note | For the Kubota L4701, 1.6 gal (6.1 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Coolant type note | The captured coolant type for the Kubota L4701 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 Kubota L4701 antifreeze mix is listed as Kubota recommends a 50: 50 ethylene glycol-based coolant-to-water mix for the L4701 tractor to protect against freezing and overheating. That is the normal protection range for freezing, boiling and corrosion control |
| Engine context note | For the Kubota L4701, the supporting engine specs are engine model V2403-CR-E4, engine horsepower 47.3 hp (35.3 kW), and displacement 2.4 L (146.5 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | For a coolant change on the Kubota L4701, 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 L4701 Coolant Capacity FAQ
How much coolant does the Kubota L4701 take?
The main coolant amount captured for the Kubota L4701 is 1.6 gal (6.1 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 L4701?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota L4701, the captured coolant type is ethylene glycol-based coolant and ASTM D3306 compatible.
What antifreeze mix does the Kubota L4701 use?
The captured antifreeze mix for the Kubota L4701 is Kubota recommends a 50: 50 ethylene glycol-based coolant-to-water mix for the L4701 tractor to protect against freezing and overheating. A 50/50-style mix is the common practical answer unless your manual or climate calls for something different.
When should the Kubota L4701 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 L4701 coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota L4701, the supporting engine data is engine model V2403-CR-E4, horsepower 47.3 hp (35.3 kW), and displacement 2.4 L (146.5 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.
