Funny we have more than a few GM vehicles in fleet use and have run Dex in them all the way to half a million miles with absolutely no issues. Even our newest vans have an open overflow tank. Only our Silverados have a pressurized one.

Yes.

My family has owned at least three GMs with Dex-Cool and all were fine. I use OEM coolant exclusively, whether that's Dex-Cool in a GM, HOAT in a Chrysler, Honda blue in our current cars, etc.

Intake manifold gaskets and dex cool were 80's and mostly 90's problems in my experience.

Not sure how it was an 80s thing since it didn't go into GMs until 1996.
