Overheating
This should be an easy one I think. 1977 vette, auto. If the radiator is pushing coolant into the overflow tank, what does this mean? while this was happening, the temp was increasing as well. what can cause this to happen?

Basically all of the radiator coolant was forced into the overflow tank and then the overflow tank was venting it overboard. I just finished draining/flushing the system...there was water left in the radiator when I tried to drain what was left. the cap was tight, all hoses look good. the water pump is working I think becuase when I flushed the radiator, I did it with the engine running and it was moving water through the stytem. I am suspect that the pump maybe going...is there anyway to tell? is this a hard thing to fix?

Stewart pumps recommends 3 holes only if you plug the internal bypass cicuit, which they do in there better pumps.
Using the bypass, 1 hole is enough.
Most tstats come with a hole that is less than 1/32"
