Kubota M135G Coolant and Engine Notes
| Coolant capacity note | The Kubota M135G’s key coolant figure here is 8.66 gal (32.8 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Coolant type note | For the Kubota M135G, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible |
| Antifreeze mix note | The Kubota M135G antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Engine context note | For the Kubota M135G, the supporting engine specs are engine model V6108-TI-CRS, engine horsepower 135 hp (100.7 kW), and displacement 6.1 L (373.8 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | The practical service move for the Kubota M135G: buy enough coolant for 8.66 gal (32.8 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota M135G Coolant Capacity FAQ
What is the cooling system capacity of the Kubota M135G?
The Kubota M135G cooling system capacity is shown as 8.66 gal (32.8 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota M135G?
Use ethylene glycol-based coolant, Kubota Genuine 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 M135G?
Not for normal long-term use. The Kubota M135G 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 M135G?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota M135G is the service interval in the operator manual.
What engine specs affect Kubota M135G coolant capacity?
The captured engine context is engine model V6108-TI-CRS, horsepower 135 hp (100.7 kW), and displacement 6.1 L (373.8 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.
