Kubota M115GX-III Coolant and Engine Notes
| Coolant capacity note | The Kubota M115GX-III’s key coolant figure here is 6.5 gal (24.6 L) for cooling system capacity. Use that before buying coolant or draining the system |
|---|---|
| Coolant type note | Coolant type for the Kubota M115GX-III is listed as ethylene glycol-based coolant. 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-III coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Coolant change interval note | The captured coolant change interval for the Kubota M115GX-III is every 1,500 hours. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Kubota M115GX-III 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-III, use 6.5 gal (24.6 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-III Coolant Capacity FAQ
What is the Kubota M115GX-III coolant capacity?
