Kubota M105GX-IV Coolant and Engine Notes
| Coolant capacity note | For the Kubota M105GX-IV, 2.65 gal (10 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 M105GX-IV: 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 M105GX-IV, 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 M105GX-IV: engine horsepower 111 hp (82.8 kW) and displacement 3.8 L (231.9 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 M105GX-IV, plan around 2.65 gal (10 L) and confirm the final level after air works out of the system |
Kubota M105GX-IV Coolant Capacity FAQ
How much coolant does the Kubota M105GX-IV take?

Does coolant type matter on the Kubota M105GX-IV?
Yes. Capacity tells you how much to buy; coolant type tells you what to buy. For the Kubota M105GX-IV, the captured coolant type is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible.
What antifreeze mix does the Kubota M105GX-IV use?
The captured antifreeze mix for the Kubota M105GX-IV 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 M105GX-IV 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 M105GX-IV coolant capacity?
The captured engine context is horsepower 111 hp (82.8 kW) and displacement 3.8 L (231.9 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.
