"Dex-Cool" antifreeze? Some GM cars have composite intake manifolds and I was told by mechanics and I read on the web that that manifold gets eaten up by antifreeze. Several years after I purchased my GM car, I learned that I needed to change that orange weird colored Dex Cool out and put in the Green anti freeze since the Green kind would not corrode the engine. Is there a class action law suit on this problem? What do you know about these GM cars and the damage caused by anti-freeze?
