Kubota A-155 Coolant and Engine Notes
| Coolant capacity note | For the Kubota A-155, 1.59 gal (6 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 A-155 radiator figure is 1.59 gal (6 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | For the Kubota A-155, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant |
| Antifreeze mix note | The Kubota A-155 antifreeze mix is listed as 50/50 coolant and distilled water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Engine context note | For the Kubota A-155, the supporting engine specs are engine model D905 and displacement 0.9 L (54.9 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | The practical service move for the Kubota A-155: buy enough coolant for 1.59 gal (6 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota A-155 Coolant Capacity FAQ
How much coolant does the Kubota A-155 take?
The main coolant amount captured for the Kubota A-155 is 1.59 gal (6 L). Buy a little extra so you can top up after the engine warms up and cools down.
Does coolant type matter on the Kubota A-155?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota A-155, the captured coolant type is ethylene glycol-based coolant.
What antifreeze mix does the Kubota A-155 use?
The captured antifreeze mix for the Kubota A-155 is 50/50 coolant and distilled water mix. A 50/50-style mix is the common practical answer unless your manual or climate calls for something different.
When should the Kubota A-155 coolant be replaced?
Use the service interval in the operator manual as the service guide. Coolant can look okay but still lose corrosion protection over time.
Why does the Kubota A-155 coolant amount differ from other models?
Coolant capacity changes with engine and radiator setup. For the Kubota A-155, the supporting engine data is engine model D905 and displacement 0.9 L (54.9 cu in).
Mistakes do happen. Tractor coolant specs can change by year, market, engine, radiator, cab/heater setup and service procedure. Please check the operator manual, decal information and official kubotausa.com website for official information before draining or refilling the cooling system.
