Kubota M8580 Coolant and Engine Notes
| Coolant capacity note | For the Kubota M8580, 11.81 gal (44.7 L) is the main coolant capacity captured. Use it as a refill planning number, then confirm the final level at the machine |
|---|---|
| Coolant type note | Use the right coolant formula for the Kubota M8580: ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | For the Kubota M8580, 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 M8580: engine horsepower 85 hp (63.4 kW) and displacement 4.7 L (286.8 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota M8580, plan around 11.81 gal (44.7 L) and confirm the final level after air works out of the system |
Kubota M8580 Coolant Capacity FAQ
What is the cooling system capacity of the Kubota M8580?
The Kubota M8580 cooling system capacity is shown as 11.81 gal (44.7 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota M8580?
Use ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. The blunt rule is simple: match the manual’s coolant spec and do not mix unknown coolant formulas.
Should I use straight water in the Kubota M8580?
Not for normal long-term use. The Kubota M8580 should use 50/50 coolant and water mix or the manual’s specified coolant mix so the system gets corrosion, freeze and boil protection.
Does old coolant matter in the Kubota M8580?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota M8580 is the service interval in the operator manual.
What engine specs affect Kubota M8580 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.
