rad and coolant, TPEFI related

[George M. Dailey]

I think you mised the reason why he had to use straight ethylene glycole. As
I understood it, this was the only liquid (reasonable) that had a vapor
pressure low enough at the required operating temperature to permitt normal
engine gaskets to hold. I don't know the actual conditions. But, unique
applications require unique solutions. Did you know that some nuclear
reactor are cooled with molten elemental sodium!
