I received my new radiator this morning. I also replaced the water pump with a leakless water pump. This evening, my wife took the Model A for a short road trip. After 25 miles at 50-55 mph, I am pleased to report that the overheating problem seems to be gone. Having said that, I have to say that driving a Model A at 45 mph is much more fun than driving at 55 moh. But, it is great to know that I can drive that fast without overheating. Thank to all for all of your thoughts and ideas.
