Kubota GM56 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GM56, 2.17 gal (8.2 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Coolant type note | Coolant type for the Kubota GM56 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 GM56 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 GM56 is every 700 hours. Old coolant can lose corrosion protection even if the tractor still runs cool |
| Engine context note | The Kubota GM56 engine data captured here is engine horsepower 24.8 hp (18.5 kW) and displacement 3.3 L (202.5 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | When refilling the Kubota GM56, 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 |
Kubota GM56 Coolant Capacity FAQ
What is the Kubota GM56 coolant capacity?
