I just went thru major problems with overheating on my new 59 TF w/ a 235
six. Afer a new radiator, and t'stat, it still over heated. The previous
owner had replaced the stock radiator cap with a 16psi rating, and as soon
as I went back to the stock 7 psi, she runs great. I am guessing it might be
due to the rating of the head of the water pump. You might want to check to
see that you have the correct cap.
