Kubota GL-400 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GL-400, 1.66 gal (6.3 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 | The captured coolant type for the Kubota GL-400 is ethylene glycol-based coolant. Do not mix unknown coolant types unless the label and manual say they are compatible |
| Antifreeze mix note | The Kubota GL-400 antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control |
| Coolant change interval note | For the Kubota GL-400, the service interval is listed as every 2 years and every 1,500 hours. Time matters too, not just engine hours |
| Engine context note | For the Kubota GL-400, the supporting engine specs are engine horsepower 40 hp (29.8 kW) and displacement 2.2 L (134.3 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 GL-400, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
