Do I misunderstand?

Under ideal conditions, 20 degrees is my understanding of the design range. Assuming everything is operating properly, most importantly the radiator. You need the temperature difference (top to bottom) to have the thermal syphon system work properly. It moves 34 to 36 gallons per minute. Boiling coolant will greatly effect flow.
Cooling system is very simple. It will even work without fan belt or when car is not running.
I highly recommend to anyone that is really interested in understanding the Model A cooling system and how easy it is to trouble shoot problems. To take a moment and read the following.
Please Goggle “Rocky Mountain Model A Club Cooling System Presentation”.
We all have developed our own views on everything in life, but this report is very hard to argue with. Enjoy.
