Kubota M125G Coolant and Engine Notes
| Coolant capacity note | For the Kubota M125G, 3.17 gal (12 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Radiator capacity note | Radiator capacity is listed as 3.17 gal (12 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 M125G is ethylene glycol-based coolant, Kubota Genuine Coolant, and long-life 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 M125G coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Engine context note | The Kubota M125G engine data captured here is engine model V3307-CR-TI-E5, engine horsepower 123.2 hp (91.9 kW), and displacement 6.1 L (373.7 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | For a coolant change on the Kubota M125G, 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 M125G Coolant Capacity FAQ
What is the cooling system capacity of the Kubota M125G?
The Kubota M125G cooling system capacity is shown as 3.17 gal (12 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota M125G?
Use ethylene glycol-based coolant, Kubota Genuine Coolant, and long-life coolant. 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 M125G?
Not for normal long-term use. The Kubota M125G should use 50/50 coolant and 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 M125G?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota M125G is the service interval in the operator manual.
What engine specs affect Kubota M125G coolant capacity?
The captured engine context is engine model V3307-CR-TI-E5, horsepower 123.2 hp (91.9 kW), and displacement 6.1 L (373.7 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.
