GM legally got their liability limited on their marvelous invention DEXCOOL. They say it was limited to only a few models and a few engines. I say horsepuckey! Maybe to them that's true but I beg to differ. The gaskets on the waterpump are leaking antifreeze. It is for now a very minor drip. I work with someone who just repaired his. We both had discussed it being the actual waterpump but after looking into it closely we found the weep holes to be bone dry and the leak coming from the gaskets between the pump and block. Another fine piece of GM engineering!
