Coolant for 10 kW BLDC motor

(1/1)

Pontus:
In winter temperature drops below 0 C where I live. Therefore I plan on use some kind of antifreeze for the coolant loop.

I would like NOT to use the antifreeze of choice for internal combustion engines - glycol, which is which tend to be rather sticky.
I'm thinking of using ethanol/alcohol instead. A 50/50 mix would be good down to -28 C.

Is there any considerations regarding aluminium and alcohol?
