Has anyone discovered a magic elixir that will seal a crack in a plastic radiator tank? One of the tanks on the radiator in my S-Jimmy has a small crack in it, but all of the radiator repair epoxies that I've found don't list plastic as something they will stick too. /forums/images/icons/mad.gif GM wants $66 for a new side tank, plus $48 for the gaskets! /forums/images/icons/shocked.gif If I can't find a cheaper way to fix it, I'll just buy a complete radiator. It's only a few bucks more! This radiator appears to be in fine shape other than this crack, even though it is 11 years old.
