@gene-kruger Gene, I split your question off into it's own thread. As for your question, is it boiling over? Is the gauge showing hot? Did the problem just start? If so, did it start after work was done on it? More details about the issue will help us help you.

I went on a week long early six rally where the temperatures were in the high 80's.  We drove over grades of up to 8,000 feet.  my temperature gage was often near the boiling point and numerous times I either boiled over and or lost a lot of water out the overflow tube.  This has been a problem for me on previous rallys.  I have a 1936 207 engine in the 1933 which has been rebuilt.  I make sure the packing nut is snug on the water pump.  No other cars had boiling problems that I know of.  There were 5 1933 Chevys on the rally.
