jumpinjivinjoe 0 Posted July 16, 2009 I have a 1936 Dodge Coupe. I recently filled up the radiator to see if it had any leaks. I found an aggressive leak that has an 1/8" stream. There is probably more leaks. Do you know any products or techniques that could fix old radiator leaks? Share this post Link to post Share on other sites
keiser31 3,637 Posted July 17, 2009 Any parts store should carry "Radiator Stop Leak". It's cheap and lasts a long time if you use it correctly. Share this post Link to post Share on other sites
jumpinjivinjoe 0 Posted July 17, 2009 That sounds like my best bet. Two bottles of it would probably seal the hole up.Thanks Share this post Link to post Share on other sites
