Kubota L5740 Coolant and Engine Notes
| Coolant capacity note | The Kubota L5740 coolant spec points to 2.17 gal (8.2 L). Do not rely on the radiator-only amount if the full cooling-system capacity is available |
|---|---|
| Radiator capacity note | For the Kubota L5740, the captured radiator capacity is 2.17 gal (8.2 L). If you are doing a full drain, check the full cooling-system capacity too |
| Antifreeze mix note | For the Kubota L5740, the captured mix is Kubota recommends a 50: 50 ethylene glycol-based coolant-to-water mix for the L5740 tractor to provide freeze and corrosion protection. Straight water is not the right long-term answer unless you are only flushing the system |
| Engine context note | Engine context for the Kubota L5740: engine model V2403-M-TE2, engine horsepower 59 hp (44 kW), and displacement 2.4 L (148.5 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | For a coolant change on the Kubota L5740, 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 L5740 Coolant Capacity FAQ
How much coolant does the Kubota L5740 take?
The main coolant amount captured for the Kubota L5740 is 2.17 gal (8.2 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 L5740?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota L5740, the captured coolant type is the coolant type specified in the manual.
What antifreeze mix does the Kubota L5740 use?
The captured antifreeze mix for the Kubota L5740 is Kubota recommends a 50: 50 ethylene glycol-based coolant-to-water mix for the L5740 tractor to provide freeze and corrosion protection. A 50/50-style mix is the common practical answer unless your manual or climate calls for something different.
When should the Kubota L5740 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 L5740 coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota L5740, the supporting engine data is engine model V2403-M-TE2, horsepower 59 hp (44 kW), and displacement 2.4 L (148.5 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.
