I used strait vinegar into a new radiator to clean out the block in my Model A. The new radiator had a flaw and leaked where the upper neck is soldered to the top tank. What a mess in the engine compartment and onto my slick paint job.
I also found vinegar must be followed by baking soda to get a clean radiator and block.
