That was a good video. Thats one hell of a job. I think I read several articles about Law Suits pertaining to DEX-COOL becomming corrosive and damaging Intake Manifold gaskets. It seems that its not so much DEX-COOL but the material the gaskets are made of. I had an 03, 3.1 base model Grand Prix I sold it at 73000 mi. I never noticed any cooland mixing with oil. I did maintain that car pretty well. I now have an 07, Grand Prix GT I've heard the Manifold gaskets on the series III vehicles is a better material. So what do ya all think, was it DEX-COOL or the gaskets? I have about 32000 mi on my GT should I just stick with DEX-COOL or go with the conventional Green Coolant.
