Routine service revealed that I have an antifreeze leak in the manifold area.

- Morgantown, WV, USA

I have been told by two mechanics that I need to change my antifreeze from dex-cool to ethylen glycol, as the dexcoolant is dirty and sugary and I am looking at electrolisis problems in my cooling system if I don't change it. Why would a reputable company like Buick put an inferior product in their vehicle" is there a class action suit being filed against dex coolant".
