I have used this stuff in big diesels, some of the properties are useful in htis application, anybody using it in their small vehicle?
Its a waterless coolant, that runs at 0 PSI and boils at 375. Can allow higher engine temperatures.
Here one page about it... (No connection just an example...)
Evans HDTC waterless coolant for heavy duty applications
I could see a electric water pump with a speed controller allowing higher temperatures at cruise under light load.
Just wondering
