I've already done the other cars over the years. The '94 Camaro, first one I owned with DexCool, suffered a complete coolant dump about 5 years ago when a freeze plug rusted through from the inside-out. I wrote it off to a bad freeze plug. Having seen the insides of my overhauled 3800 Series II project, I know different.
The '87 Camaro and '90 Bonneville never had DexCool in them, and their original radiator cores look brand new.

I used to use the Dex in my 95... Years back I switched to Prestone Longlife.. And when I finally puled the lower gaskets after the prestone the gaskets looked like brand new...
I like My Prestone

I just had my coolant flushed and switched to prestone too. If the engine had Dex in it until about 2 weeks ago, will the green stuff prolong the life of my gaskets/ etc. or am I still screwed and should I get it done as soon as possible :?

Rach.....the damage is already done. You still need to replace your LIM gaskets. And do the upper while you're at it.
Every car here that has had DEX for over a year or two should change it soon. My opinion, but well-founded by our research and experience.

Okay. Mine had dex for nine non serviced years.
It was recently flushed in June. I am running the orange stuff still (Halvoline)....should I flush it over to the Green stuff soon?
Cause that is easy enough to do...
