NAIOA and their staff seem to find no trouble.

GM and the people on the forum link above are blaming it on poor maintenance.

What should I say to them ? I know this forum has experience in this.

Wasn't "No maintenance, permanent coolant" one of the original selling points for Dexcool?

Neglecting basic maintenance is not new; it has been an issue for as long as there have been cars.

They claim the gunk is from air in the system.

Both my Bonneville and my Impala had no leaks.

You didn't read.

Go read those links.

When air gets in the system, DEX-cool turns _________.

Any questions? ALL systems will have air introduced into them at one time or another. There is no 'perfect' cooling system.

They told me the same thing and got very defensive about it. That was the last time I ever logged in there

There are some people out there that didn't ever bother to research the actual chemistry and physics behind it.

I'm very clear in my appeal on my page to encourage everyone to back up my sources and compare what I found. Research it for yourself.

Not a single DEX info page that I've seen has EVER researched the physical and chemical interaction between the gasket material and the chemical components in the DEX.

My page now takes up to 10k hits a month (10.3k is my record so far).

Did I PROVE it? No. But I think I've made the best TECHNICAL argument to date. And alot of shops and sources out there agree with me. Before AND after my page hit the public.

.. It'* like , I like that place a LOT.. but sometimes, things just bother me about that forum.

I mean, every forum will never be perfect.. but.. would these cars be recalled for anything else? Everyone believes something different, I guess.

I'm willing to bet you have a few old gaskets laying around your place. Cut some up and put them in some jars. Then fill those jars with different kinds of coolent. Even do a disstiled water as a control. Label them and let them sit on teh shelf for some period of time. Take pictures every few months. If there'* a reaction, it will show. Then there'* your proof.
