Kubota L3400 Coolant and Engine Notes
| Coolant capacity note | For the Kubota L3400, 1.61 gal (6.1 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Radiator capacity note | For the Kubota L3400, the captured radiator capacity is 1.59 gal (6 L). If you are doing a full drain, check the full cooling-system capacity too |
| Coolant type note | Coolant type for the Kubota L3400 is listed as ethylene glycol-based coolant and Kubota Genuine Coolant. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas |
| Antifreeze mix note | For the Kubota L3400, 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 L3400: engine horsepower 35.7 hp (26.6 kW) and displacement 1.6 L (97.6 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | When refilling the Kubota L3400, use 1.61 gal (6.1 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
