Dexcool can cause problems with older style gaskets. A lot of GM cars and trucks began getting updated gaskets after dexcool was around for a few years. I noticed that GM intake and waterpump gaskets changed from having a red/orange material to having a light blue one instead. It seemed to take care of the leaking problems. I haven't really seen clogging, but I only worked on newer cars that came with dexcool originally.
