I just thought I'd bump this up again. I just received an email from Gerard Gibbs law firm who is the prinicipal law firm working on this class action lawsuit that seems like is going no where. Anyway have a read.

We are writing to update you on the status of the Dex-Cool litigation. This email addresses the Multi-District Litigation (MDL) multi-state case pending in East St. Louis, Illinois. It does not concern vehicles purchased in Missouri, California, or Texas, which are expressly excluded from the MDL case. Additionally, this email concerns the 3.1L, 3.4L, 3.8L, and 4.3L engine platforms, which are at issue in the MDL case. As we previously reported, plaintiffs in the MDL asked the Court to certify the following issues for resolution at trial:

1.
Whether the intake manifold gaskets in GM’s 3.1L, 3.4L and 3.8L engines (model years 1996- 2003) are incompatible with Dex-Cool engine coolant, causing the gaskets to fail prematurely; and
2.
Whether the engine cooling systems in GM’s 4.3L engine (model years 1996-2000) is incompatible with Dex-Cool engine coolant, causing excessive sludge in the engine’s cooling system.

Unfortunately, the Court denied plaintiffs’ request to certify the class. Among other things, the Court found that the differing state laws, including the requirement in some states that consumers seeking relief for breach of warranty prove “reliance” on the warranty at the time of purchase, and the possible difficulty of figuring out the cause of “sludge” on a class-wide basis, warrant against class certification. It is important for you to understand that the Court’s decision denying class certification is not a decision on the merits of plaintiffs’ case. Instead, it is a decision on whether it is procedurally appropriate for the case to proceed as a class action, as requested by plaintiffs. We are in the process of determining whether to ask the Court to certify individual state classes on behalf of a more limited line of GM vehicles. Because we have yet to decide on an appropriate course of action, if you are considering pursing a “gasket” or “sludge” claim against GM, such as in your local small claims court, you should not delay in doing so, as the passage of time may effect your rights. If you have a vehicle with a 3.1L, 3.4L or 3.8L engine and have experienced a lower intake manifold gasket failure, and would like us to consider pursing a “gasket” class action limited to your state, please let us know and we will expedite the necessary research and let you know whether such an action is feasible under your state’s laws. If you would like us to undertake such research, you may contact us at [email protected].

Dex-cool was in my Blazer when i bought it, but no longer. I went with the regular green Prestone. I hear Dex-cool may be a culprit in someway helping to cause intake manifold failure, but well who knows??

Well, the best way to handle dex-cool is to flush it out real good and refill with 50/50 mix of the green stuff. No more leaky intakes, water pumps, t-stat housings, or plugged heater cores. This may not apply everywhere, but my experience as a dealership tech in the middle of the desert says dex-cool is junk.

Go Green!

While that may have been the suggested practice when dexcool first came out, many other GM sites that I am a part of are now experiencing intake manifold failures on GREEN COOLANT ONLY engines after full rebuilds. Now, is it the coolant? Or is it just bad intake manifold designs...? As suggested in the email from the law firm above, it is poor intake gasket design and/or material choice that is causing all of the problems.

Im in the middle of the desert (phoenix, az) and Dexcool works just peachy for me. Yes it finally broke down after over 100k miles but ive had the green stuff do that too. Basically my whole philosophy on coolant is this, so long as you take care of it and dont get a bunch of garbage in it, it should work no matter what color or brand. Yes certain brands like prestone have additives that do prolong life and that may be a plus but who knows, you may not nessesarily need that. Plus in light of this particular thread and other testing done by other third parties, most coolants perform right on par with one another in the same conditions. So just go with what ever speaks to you. Coolants main job is to keep your car temperature controlled over a prolonged period of time and ya know what, i dont think they would release coolants to the public if they didnt do just that (thus why you dont see apple juice as a coolant).


Now if you really want to know what i think, i say go pentosin, purely for the fact that stuff is blue, how cool is that, LOL.

I've personally resealed about 500+ GM intakes, maybe 5 had green coolant in them. So it sounds to me like you have more website memberships than work experience...

All I'm saying is Dex-Cool is far more problematic than the green stuff. Any dyed-in-the-wool GM guy or girl can agree with that. Is that too much to state?

More like Dex-NOT-cool! I have a bad story about it. I have an 01 that started overheating and losing coolant when summer started. After reading up on Dexcool, I decided to go with a flush and getting some fresh green stuff. I don't know what happened, but I opened the overflow and it looked like someone poured a gallon of used oil in the thing. We took it out, hosed it, cleaned it, and put it in a parts washer for over an hour, and it was still black on the inside! The coolant after the flush was all nasty and brown and sludgy. Just plain ol' bad news. I'm happy to say that green is running fine and staying very cool even in 110+ degree heat while off roading. And that's where I need it! I do know people who have no problems with the stuff, and that's great. But in my opinion; there's nothing cool, about dexcool. Thanks for listenin' to my story!

LOL You've got me. I do way too much time reading and don't ever get my hands dirty. LMAO!!! You're great! ROTF... I don't have to say anything more than what has already been said in this thread. If you haven't taken the time to read through it, then please do so now. Please take note of the other few GM techs that we have here and their opinions.

Also, please go read up on BonnevilleClub.com. MANY, MANY members there were of the EXACT opinion as those here until many of them swapped out their intake manifold gaskets and went with EG coolant. Only to have failures in the EXACT same manner later on. Why do you think that the lawsuits that started out as being against GM for Dexcool have now changed their tune. Now they are all about poor intake gasket design. Doesn't take a rocket scientist.

That's all I have to say. Time to go swap out the starter on my Dad's pickup. Oh wait, that's right, I only read and can't actually do mechanical work... Please[&o]
