Kubota GB145 Coolant and Engine Notes
| Coolant capacity note | The Kubota GB145’s key coolant figure here is 2.17 gal (8.2 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Coolant type note | Coolant type for the Kubota GB145 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 GB145 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 GB145 is every 700 hours. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Kubota GB145 engine data captured here is engine model D1105, engine horsepower 14.5 hp (10.8 kW), and displacement 0.7 L (42.7 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | When refilling the Kubota GB145, use 2.17 gal (8.2 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
