Kubota GB115 Coolant and Engine Notes
| Coolant capacity note | The headline cooling-system number for the Kubota GB115 is 2.17 gal (8.2 L). Buy enough coolant before opening the drain plug |
|---|---|
| Coolant type note | The captured coolant type for the Kubota GB115 is ethylene glycol-based 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 GB115 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 GB115 is every 700 hours. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Kubota GB115 engine data captured here is engine model Z482, engine horsepower 10 hp (7.5 kW), and displacement 0.5 L (30.5 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | For a coolant change on the Kubota GB115, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
