I've seen some alarming reports on various national television news programs regarding the performance of Dex-Cool. There is currently a class action lawsuit against GM by vehicle owners trying to recover for damages caused by this coolant. The programs I've seen have presented arguments both praising and condemning this product. I personally would never touch it after seeing the interiors of radiators infected with this product. If you plan to use Dex-Cool, you should research these claims on your own. By the way, was anyone else amused by the name of the original poster of this topic?
