Hello. I have a 1955 bel air. My original radiator has a few pin holes in it. It doesn't overheat or lose a significant amount of.fluid. I was wondering if I should pull my radiator and have it repaired or just use the stop leak stuff that you put in the radiator. All opinions are welcome. Some day I plan on putting ac in the car but that might not.be for a long time. I have a 350 in the car now and it runs great.
