Kubota GL301 Coolant and Engine Notes
| Coolant capacity note | For the Kubota GL301, 2.17 gal (8.2 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 | Coolant type for the Kubota GL301 is listed as ethylene glycol-based coolant. The safest move is to use coolant that matches the manual’s spec rather than mixing random formulas |
| Antifreeze mix note | The Kubota GL301 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 GL301, the service interval is listed as every 700 hours. Time matters too, not just engine hours |
| Engine context note | For the Kubota GL301, the supporting engine specs are engine model D1503 and engine horsepower 30.6 hp (22.8 kW). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | When refilling the Kubota GL301, use 2.17 gal (8.2 L) as the planning number and 50/50 coolant and water mix as the mixture guide. Recheck the level after the thermostat opens |
