Kubota L5450 Coolant and Engine Notes
| Coolant capacity note | For service planning, the Kubota L5450 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 | Radiator capacity is listed as 2.17 gal (8.2 L). The full cooling system can be higher because coolant also sits in the engine and hoses |
| Coolant type note | Use the right coolant formula for the Kubota L5450: ethylene glycol-based coolant and Kubota Genuine Coolant. Cheap wrong coolant is not a smart saving if it causes corrosion or deposits |
| Antifreeze mix note | The 50/50 coolant and water mix mix gives the Kubota L5450 coolant system a sensible balance of freeze protection, boil protection and corrosion protection |
| Engine context note | The Kubota L5450 engine data captured here is engine horsepower 59.5 hp (44.4 kW) and displacement 2.7 L (167.6 cu in). Bigger engines usually need more coolant and more careful refill bleeding |
| Refill note | Coolant changes are simple but easy to do sloppily. On the Kubota L5450, plan around 2.17 gal (8.2 L) and confirm the final level after air works out of the system |
