Quote from How to Keep Your Rat Rod Cool :
How is your engine? Although this may sound silly, are your cooling passages clogged or badly rusted? If an engine has been sitting for a while, many things can crawl into it and make a home, in turn clogging vital coolant passages in your Rat Rod`s engine. Pre‐pressurizing your engine before adding final clean coolant can eliminate future clogs.
What about your fans? Be it a clutch type fan, or an electric fan, are they working correctly? Having a clutch fan in your Rat Rod and a backup electric fan is the way to go. The clutch fan will pull air as necessary. Have the electric fan in front of your radiator to “push“ the air through if heat conditions become excessive. Setting the electric fan on a thermostat will remove any worry about forgetting to turn on the fan before overheating.
How is your radiator? This is the heart of your cooling system and your engine! Older copper and brass radiators do not dissipate heat as well as the newer aluminum ones but will do the job if clean and sized correctly. Make sure all of the fins in the radiator all clean and free of obstructions. Have it pressure tested to make sure your Rat Rod will not leak coolant.
