Kubota GB135 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GB135, 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 | Use the right coolant formula for the Kubota GB135: ethylene glycol-based coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | For the Kubota GB135, the captured mix is Kubota recommends a 50: 50 ethylene glycol-based coolant-to-water mix for the GB135 tractor to protect against freezing and corrosion. Straight water is not the right long-term answer unless you are only flushing the system |
| Engine context note | Engine context for the Kubota GB135: engine horsepower 12.9 hp (9.6 kW) and displacement 0.7 L (42.7 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota GB135, plan around 2.17 gal (8.2 L) and confirm the final level after air works out of the system |
Kubota GB135 Coolant Capacity FAQ
