Black pepper flakes in the radiator to stop a small leak….
My preferred method of dealing with a small leak. Pepper is biodegradable and will eventually disappear, leaving to to do the repair correctly, or to add more pepper. In fact, in my modern cars, I carry a can of pepper in the glove box. It's pulled me or a complete stranger out of a jam more than once.
I don't like bars leak or similar because it will coat all the surfaces of your cooling system with no easy way to remove it.
I do this with modern cars where radiators don't cost $600-$800 greenbacks. My Model A, it get's fixed correctly because the engine cost a fortune to replace.
