Well I do have to admit that when I pulled into the gas station and saw the coolant puking out for the first time, I thought my radiator busted because of the large wet area on it. (there is a pinhole leak that I need to fix; besides the point, it must have just gotten sprayed from the overflow tank and driving) Thought that was my problem and was 90 miles from home so I put it in there to just make it home. Turns out it wasn't the issue because it did the exact same thing in less than 4 miles of driving... Still, the coolant originally was a milky brown that I saw when it puked it all out of the leaky overflow tank I had. But when you say the "block got froze", you mean like ice frozen or seized?
