Kubota L4300 Coolant and Engine Notes
| Coolant capacity note | For the Kubota L4300, 2.2 gal (8.3 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 L4300 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 | For the Kubota L4300, the captured mix is 50/50 coolant and water mix. Straight water is not the right long-term answer unless you are only flushing the system |
| Engine context note | Engine context for the Kubota L4300: engine horsepower 45.3 hp (33.8 kW) and displacement 2.2 L (134.3 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | When refilling the Kubota L4300, use 2.2 gal (8.3 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
