Kubota M1-85 Coolant and Engine Notes
| Coolant capacity note | For the Kubota M1-85, 2.17 gal (8.2 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 M1-85 radiator figure is 2.17 gal (8.2 L). Treat it as radiator context, not always the complete refill amount |
| Coolant type note | The captured coolant type for the Kubota M1-85 is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. Do not mix unknown coolant types unless the label and manual say they are compatible |
| Antifreeze mix note | The Kubota M1-85 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 M1-85, the supporting engine specs are engine horsepower 85 hp (63.4 kW) and displacement 4.7 L (286.8 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | For a coolant change on the Kubota M1-85, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
Kubota M1-85 Coolant Capacity FAQ
How much coolant does the Kubota M1-85 take?
The main coolant amount captured for the Kubota M1-85 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 M1-85?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota M1-85, the captured coolant type is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible.
What antifreeze mix does the Kubota M1-85 use?
The captured antifreeze mix for the Kubota M1-85 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 M1-85 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 M1-85 coolant capacity?
The captured engine context is horsepower 85 hp (63.4 kW) and displacement 4.7 L (286.8 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.
