Kubota KL3450 Coolant and Engine Notes
| Coolant capacity note | For the Kubota KL3450, 2.3 gal (8.7 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 | The Kubota KL3450 radiator figure is 2.3 gal (8.7 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | Coolant type for the Kubota KL3450 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 | The Kubota KL3450 antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Engine context note | For the Kubota KL3450, the supporting engine specs are engine horsepower 34.5 hp (25.7 kW) and displacement 1.8 L (110 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | When refilling the Kubota KL3450, use 2.3 gal (8.7 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
