| Coolant capacity note | The Kubota GM75’s key coolant figure here is 2.12 gal (8 L) for coolant capacity. Use that before buying coolant or draining the system |
|---|---|
| Coolant type note | The captured coolant type for the Kubota GM75 is ethylene glycol-based coolant, Kubota Genuine Coolant, and ASTM D3306 compatible. Do not mix unknown coolant types unless the label and manual say they are compatible |
| Antifreeze mix note | The Kubota GM75 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 GM75, the service interval is listed as every 700 hours. Time matters too, not just engine hours |
| Engine context note | For the Kubota GM75, the supporting engine specs are engine horsepower 74 hp (55.2 kW). Use them as context beside the coolant capacity, not as a replacement for the manual |
| Refill note | For a coolant change on the Kubota GM75, do not just dump in coolant and walk away. Fill slowly, run it up to temperature, cool it down and top up as needed |
