Coolant type note
For the Kubota GB170, coolant type matters as much as capacity. The clean captured value is ethylene glycol-based coolant
Antifreeze mix note
The Kubota GB170 antifreeze mix is listed as 50/50 coolant and water mix. That is the normal protection range for freezing, boiling and corrosion control
Engine context note
For the Kubota GB170, the supporting engine specs are engine model D1105, engine horsepower 16.8 hp (12.5 kW), and displacement 1 L (61.1 cu in). Use them as context beside the coolant capacity, not as a replacement for the manual
Refill note
The practical service move for the Kubota GB170: buy enough coolant for 1.59 gal (6 L), fill to spec, run the engine, then recheck the radiator and overflow bottle after cooling
