Kubota M1-46 Coolant and Engine Notes
| Coolant capacity note | For service planning, the Kubota M1-46 should be treated as 2.17 gal (8.2 L) coolant capacity. That is a compact tractor cooling system where a normal premixed coolant jug may cover most of the refill |
|---|---|
| Radiator capacity note | The Kubota M1-46 radiator figure is 2.17 gal (8.2 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | For the Kubota M1-46, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant |
| Antifreeze mix note | The Kubota M1-46 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 M1-46, the supporting engine specs are engine horsepower 46 hp (34.3 kW) and displacement 2.4 L (148.7 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 M1-46: buy enough coolant for 2.17 gal (8.2 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota M1-46 Coolant Capacity FAQ
How much coolant does the Kubota M1-46 take?
The main coolant amount captured for the Kubota M1-46 is 2.17 gal (8.2 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 M1-46?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota M1-46, the captured coolant type is ethylene glycol-based coolant.
What antifreeze mix does the Kubota M1-46 use?
The captured antifreeze mix for the Kubota M1-46 is 50/50 coolant and 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 M1-46 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.
What engine specs affect Kubota M1-46 coolant capacity?
The captured engine context is horsepower 46 hp (34.3 kW) and displacement 2.4 L (148.7 cu in). Engine size is one reason coolant capacity changes between tractors.
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.
