[electricboats] Coolant Recommendations

I am ready to fill my cooling system with coolant.  The controller cooler has a copper tubing and the motor is aluminum.  Hoses are PVC and the heat exchanger is copper+aluminum.   Any specific recommendations for coolant out there?   Anything to stay away from? 

I found this list on a search for coolant for aluminum motors:

The water-less coolant may be interesting? 

Seems there is no point in trying to be frugal when the whole system will take about 2 liters.  If I have to mix the coolant with water I will use distilled water. 

Thanks, Dan Pfeiffer
