Consumer complaints about DexCool in GM Engines

Consumer complaints about DexCool in GM Engines: "Dorothy of Baltimore (8/29/00):
In August 1999, my Chevy S-10 Blazer 4WD overheated on a business trip to Savannah. I had it towed to Darryl Burke Chevrolet. They stated that, for unknown reasons, the antifreeze had gotten junked up and the system needed to flushed & refilled. They had never seen this before. Four days later, it overheated on the way back to North Carolina from Savannah."
