Project "Chihuahua" '65 Formula S Restoration "Estilo Mexicano"

Install a coolant overflow container and you won't have to refill the radiator unless there is a leak in the system. If you have a transparent container, it will make diagnosis easier because you can see how much overflow there is each time you run the engine. It will automatically siphon back into the radiator as it cools off. You can monitor the cooled coolant level in the container and ad coolant as needed to the unpressurized recovery container. If you use a radiator cap with a pressure relief lever, you can safely release the pressure before removing the radiator cap if necessary.
