Kubota M115GX-IV Coolant and Engine Notes
| Coolant capacity note | The Kubota M115GX-IV’s key coolant figure here is 2.65 gal (10 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Coolant type note | Coolant type for the Kubota M115GX-IV is listed as ethylene glycol-based coolant, Kubota Genuine 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 water mix mix gives the Kubota M115GX-IV coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Engine context note | The Kubota M115GX-IV engine data captured here is engine model V6108-CR, engine horsepower 123 hp (91.7 kW), and displacement 6.1 L (373.7 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | When refilling the Kubota M115GX-IV, use 2.65 gal (10 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
Kubota M115GX-IV Coolant Capacity FAQ
What is the cooling system capacity of the Kubota M115GX-IV?
The Kubota M115GX-IV cooling system capacity is shown as 2.65 gal (10 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota M115GX-IV?
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 M115GX-IV?
Not for normal long-term use. The Kubota M115GX-IV 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 M115GX-IV?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota M115GX-IV is the service interval in the operator manual.
Why does the Kubota M115GX-IV coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota M115GX-IV, the supporting engine data is engine model V6108-CR, horsepower 123 hp (91.7 kW), and displacement 6.1 L (373.7 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.
