No more dexcool, deathcool, dexcrap, whatever you want to call it. I've heard all the horror stories and never really paid much attention to them. However, I just installed a new waterpump and decided to drain the entire cooling system. I've flushed it six times trying to get rid of the orange and look what I found in the bottom of the bucket. You guys can try and talk me out of it but tommorrow I think I'm going green.
Definetly looks and feels like engine seal material to me.
I know your feeling, I had sludge in 2 of 3 dex-cool engines the vette is the good one, I have switched the other two with Prestone yellow. My best friend is a chevy mechanic and once the sludge appears he switches them over to the conventional stuff. No problems with my other two.
How many miles on your car? How many times has the cooling system been flushed before?
If your car is high mileage and the coolant has never been changed, don't blame the problem on the coolant.
Personally, I'll stick with what GM recommends.
My car has 93k miles. I've owned the car about four years (63k miles when I bought it). I changed the coolant about a year and a half after buying it and the coolant looked fine. Coolant looked fine this time too except for the suprise in the bottom. I take exceptional care of my vehicle. I blame the coolant, unless seals are suposed to come apart.

Ya I talked to my dad who used to be a school bus mechanic and he said as soon as the buses are off warranty they would switch them to regular coolant. Apparently they had lots of problems with dexcool.
Is there any way to determine exactly what the material is that you found at the bottom of the bucket?
I just find it hard to believe that GM recommends Dexcool and it would eat up seals.
Edit: just finished doing a Google search on DexCool. You may have something there! Seems you are not the only one who has had problems with this product. Sorry I doubted your diagnosis.
What is supposed to be so special about DexCool? Is it specially designed for aluminum blocks?

I can't say with 100% certainty it is seal material. But it is plasticy, rubbery, and brittle. Only other thing it could be is hose material but I don't think so. And ya from what I have heard this stuff eats up seals.
It's your car to do with as you please. That said, do some research on this much debated topic.
Go to C5 Tech and click on "search this topic" (in the red banner). Use keywords "DEXCOOL" and read many past discussions of the pros/cons.
The old formula of DEXCOOL with factory installed tablets did cause some issues in LT1/LT4 motors when the coolant system was not maintained properly. The tablets have since been eliminated from the coolant system.
Well, I just replaced the lower intake gaskets on the wifes 01 grand am 3.4L, I think I will send my info, it would be nice to get the cost of the gaskets back. Thanks

I would think it's hose material (since the coolant travels thru lots of hoses) before I would think it's seal or gasket material, but that's just me. After all, hoses do decay over time, and small bits of hose material would float around in the coolant as it circulates thru the cooling system.
I also put two AcDelco tablets in to help correct any damage the orange may have caused. I took it for a drive and it's way faster! I'll let you guys know if anything blows up.
This suit is still pending approval by the court system. Said they sould have something by April 2008
I am part of it, I had a 2000 Pontiac Grand Am GT with the V-6 that I had to have the intake manifold gasket replaced due to DexCool issues at a cost of just over $800 in parts+labor+tax in a car my wife drove everyday to work, so I needed it done right away.
There is still no indication on what will be awarded to all the participants in the class action suit, if anything I'm sure the lawyers are being taken care of in this case..............on both sides
