Default Re: Temp diff across Radiator

Goggle “Rocky Mountain Model A Club Cooling System Presentation”. It will give you all the information needed to understand how the cooling system works.

Model A uses a syphon system aided by a water pump that helps at higher speeds.

Normal temperature difference between outlet at top of engine and inlet at bottom of engine/radiator is around 20 degrees. Syphon starts at around 180 degrees at water outlet top of engine.

Read the Cooling Presentation, it will make you an expert or at least allow you to have a good understanding of how it was designed and works. Enjoy.
