I've already done the other cars over the years. The '94 Camaro, first one I owned with DexCool, suffered a complete coolant dump about 5 years ago when a freeze plug rusted through from the inside-out. I wrote it off to a bad freeze plug. Having seen the insides of my overhauled 3800 Series II project, I know different.
The '87 Camaro and '90 Bonneville never had DexCool in them, and their original radiator cores look brand new.
