My 1932 Ford hotrod has overheated in the past. What can I do to prevent it?
Q. With summer heat on the horizon, I’m worried that my 1932 Ford hotrod will overheat, which it has in the past. I know the cooling system is operating as well as it can, and the coolant is mixed at a 50/50 ratio. Is there anything else I can do?
A. I would go over the cooling system one more time to make sure you are getting enough air flow through the radiator. If you haven’t already, try adding an electric fan. The ideal engine temperature is 195 to 200 degrees, so it’s important to have an accurate engine temperature gauge. A 50/50 mix of engine coolant to water and a 13- to 15-pound radiator cap should protect the engine from overheating to 250 degrees. Many people told me they had good luck with a coolant additive called Purple Ice, which is is a wetting agent that enhances the cooling properties of coolant mix and the water itself.
