Kubota M4800SU Coolant and Engine Notes
| Coolant capacity note | The Kubota M4800SU coolant spec points to 1.85 gal (7 L). Do not rely on the radiator-only amount if the full cooling-system capacity is available |
|---|---|
| Radiator capacity note | For the Kubota M4800SU, the captured radiator capacity is 1.85 gal (7 L). If you are doing a full drain, check the full cooling-system capacity too |
| Coolant type note | For the Kubota M4800SU, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible |
| Antifreeze mix note | For the Kubota M4800SU, 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 M4800SU: engine horsepower 51 hp (38 kW) and displacement 2.4 L (148.5 cu in). Engine size helps explain why coolant capacity changes between models |
| Refill note | The practical service move for the Kubota M4800SU: buy enough coolant for 1.85 gal (7 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling |
Kubota M4800SU Coolant Capacity FAQ
What is the cooling system capacity of the Kubota M4800SU?
The Kubota M4800SU cooling system capacity is shown as 1.85 gal (7 L). That is the number to use before draining the system.
What coolant type should I use in the Kubota M4800SU?
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 M4800SU?
Not for normal long-term use. The Kubota M4800SU 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 M4800SU?
Yes. Old coolant can lose protection even if temperature looks normal. The listed service interval for the Kubota M4800SU is the service interval in the operator manual.
What engine specs affect Kubota M4800SU coolant capacity?
The captured engine context is horsepower 51 hp (38 kW) and displacement 2.4 L (148.5 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.
