Kubota L3710 Coolant and Engine Notes
| Coolant capacity note | The Kubota L3710 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 | Radiator capacity is listed as 2.17 gal (8.2 L). The full cooling system can be higher because coolant also sits in the engine and hoses |
| Coolant type note | Coolant type for the Kubota L3710 is listed as ethylene glycol-based coolant and ASTM D3306 compatible. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas |
| Antifreeze mix note | The 50/50 coolant and distilled water mix mix gives the Kubota L3710 coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Engine context note | The Kubota L3710 engine data captured here is engine horsepower 38.5 hp (28.7 kW) and displacement 1.9 L (115.9 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | When refilling the Kubota L3710, use 2.17 gal (8.2 L) as the planning number and 50/50 coolant and distilled water mix as the mixture guide. Recheck the level after the thermostat opens |
Kubota L3710 Coolant Capacity FAQ
What is the cooling system capacity of the Kubota L3710?
The Kubota L3710 cooling system capacity is shown as 2.17 gal (8.2 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota L3710?
Use ethylene glycol-based coolant and ASTM D3306 compatible. 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 L3710?
Not for normal long-term use. The Kubota L3710 should use 50/50 coolant and distilled 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 L3710?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota L3710 is the service interval in the operator manual.
What engine specs affect Kubota L3710 coolant capacity?
The captured engine context is horsepower 38.5 hp (28.7 kW) and displacement 1.9 L (115.9 cu in). Engine size is one reason coolant capacity changes between tractors.
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.
