Now i'm pretty goddamn pissed off my 3.4L has a blown head gasket and i know its not due to the way i drive or where i live, because im not an asshole driver and i live in Baltimore, Md where the weather is pretty steady. Anyway i have no doubt in my mind that Dexcool is the reason behind my head gasket. I was looking on google and found this site http://www.cwcd.com/CM/MassTorts/MassTorts5.asp and this one http://www.consumeraffairs.com/automotive/gm_dexcool.html . I talked to my dealership and they said that they have no clue what i was talking about. That just pissed me off and i flipped out on the guy, felt damn goooood after all the money i've spent on this crap ass car. Anyway any1 else here think dexcool may have damaged your car?

I know for a fact dexcool is the cause of failure for my intake manifold gasket. my mechanic told me so. It's a big money maker for gm. whenever you get your head gasket problem fixed, have mechanic put old school green radiator fluid in. it works better

A worker in Autozone told me yesterday, that they got word from their corporate office to remove DEXCOOL from all Autozone Shelves, permanently.

Gm Is Playing Us Like A Fool. That F****ng Pisses Me Off. I Thought 96 & Older Impala's Were Built Better Than The New Camary Oops I Mean Impala. It's Just That There Both Fwd Under Powered And Bland.

AND STILL ANOTHER BUNCH OF GM BASHERS
General motors did not invent freakin Dexcool the just use is because it is enviromentally safer than the old green stuff. Although Dexcool is a barrel of recycle Donkey P*SS. it is not GM's fault.

WOW, this whole thread has answers from fans that have no clue!! 1st, I have a 95 impala, and I put dexcool in it and it did not come that way from the factory!!!!! Check this out..I have no problems with it either! But, let me add..I do maintain my cars myself, so no one will lead me down a road to rob me! I bet, that some people here still think you need to change oil every 3000 mile to make your engine run good, listen up folks!! Things change and the hillbilly that you let work on your car has no clue!

In my neck of the woods,(Central NY) a lot of the stores are now carrying a "universal mix" antifreeze which can be used in any vehicle that uses Dex Cool or he ethylene glycol green antifreeze. My question is, has anybody used it yet, and what is their opinion of it? I couldn't find any green antifreeze at our local Wal Mart, just the new universal and a bottle or two of DexCool.It seems that the stores will probably drop the 2 different antifreezes and just carry the universal stuff. I want to make sure that this new formula is better than the Dex Cool and just as good as the ethylene glycol I am used to using in the past.

The new stuff that you can use is Zerex G-05; that's a better alternative to DEX-COOL; wish I would've known that for my brother-in-law; DEX-COOL helped ruin his motor in his '99 Buick Century; it was running fine one day, NO LEAKS AT ALL, I pressure checked his cooling system and never heard a hiss at all, yet it still overheated and it melted his cylinder head. Thanks GM, you really screwed us over. Does anyone know if there's any lawsuits pending against them?

Okay... Let me start by saying I have been doing a lot of research lately into this mess concerning Dex Cool. I have a '97 Venture that needed the intake gaskets replaced at around 62-63,000 miles. I've been thinking about replacing the Dex with the old ethylene glycol based antifreeze. This morning I called a local radiator shop that has been in our area over 75 years and is well respected. I wanted to get his opinion on the matter. He told me that he is working with some people concerning the class action suit, and couldn't comment much at this time, but he was able to tell me that he believes the problem with the gaskets is not really related to the antifreeze but rather poor design of the engine and poor choice of materials that went into the gaskets themselves. I asked him about switching over and he said you could, but what he really reccomended was keeping the Dex in the engine and replacing it every year. He said if the lawsuit comes out and the consumer wins big, you have a better chance of a claim if you still have the Dex in. He said the main focus of the lawsuit is the sticker GM put in the engine compartment stating the Dex was good for 5 years 150,000 miles, which is wrong. They made the mistake of putting that there, when it was found that Dex really doesn't last as long and should be replaced more frequently than is stated. He also said the Dex can break down sooner than the ethylene glycol based green antifreeze, warranting the yearly change. I plan on continuing the research and post anything else I can find. He also stated that he wouldn't put DexCool in a vehicle that did not come with it as the engine and components need certain ingredients in the green stuff that the Dex doesn't have, one of them being silica.

hey all, heres some more info:
http://www.wcpo.com/wcpo/localshows/dontwasteyourmoney/20299ce7.html
http://www.bonnevilleclub.com/techinfo/?article=35

would GM continue to put a product in their vehicles thats been causing problems in so many vehicles (GMC, Chevy, Buick, etc)?? It could be the way the owners take care (or don't) of their cars. The 5 year 150,000 is just a reccomendation on the longest you can go. Just because you can get 300 miles to the tank until it is bone dry and you're sputtering doesn't mean you are going to, does it?
I'm not trying to stick up for GM, but theres some of people that never do ANY maintainance on their vehicles. And yes, theres always a "bad" part made, seals not properly sealed.


P.S. a side note chevy no longer puts the 5yr/150,000mi "promise" on later model stickers

thats a good idea to keep dex in and wait for the class action suit, but you might as well hold out for the lotto. I doubt chevy would admit they're at fault. It would cost them so much it would cripple them. I think they know they're at fault but when they see the money they make off of repairs they say instead of admitting to wrong doing lets just gradually work in a new coolant into the picture and hope the public will shut up. then they can take the money they made off the repairs and invest in foriegn markets, then when they loose their butts in that they'll just have a price hike.

The 5year/ 150,000 mile thing for DexCool is under PERFECT OPERATING CONDITIONS We all know that theres no where u can drive that ur gonna have perfect operating conditions.

my intake started to leak with less than 4000 miles on my car im sure it wasnt the DEX that caused it. its a common problem with this engine.

I just recently had to have the intake manifold gasket replaced in my impala @ 53k miles - cost me about $1400 to have all the work done. I don't think this is normal. I checked out the websites about dexcool, Any possibility this can be related to the dexcool issue? If you can send me an email with IMPALA as the subject as my email filtering software will allow it through.

My understanding of the matter, from what I've been reading concerning the Dex Cool problem is that the intake gasket leak is more of poor engine design/ improper gasket material choice. The gaskets were primarily plastic and degraded over time due to the hot/cold cycle of the engine. GM revised this gasket @ July 2002 and also has issued new intake bolts to be used. There have been reports of loose intake bolts and these new ones have have a threadlocker material on the threads. Even some aftermarket gasket makers have been incorporating metal in their gaskets for these engines. The Dex Cool issue has a lot to do with the product degrading in a shorter amount of time than was originally stated by GM. With it's problems of gelling and clogging up owner's engines, and losing it's protective characteristics. On a side note, GM has discontinued the 3.4 liter engine and is replacing it with a 3.5 in the Venture's replacement , the Uplander. I'm not sure if they will do the same for the Impala and other GM models at the same time, although IMO that would be a smart move. :banghead: <--- GM owners with Dex Cool problems

Well I opened a case with the Chevy assistance center on the matter. They stated they would call me back last Tuesday, but that never happened. I need to call them again. The repair bill for the intake was only $740 and change, I did notice bolts and material as you stated on the repair bill. The remainder of the bill was for 50k mile services, brakes, etc...

One thing I did not mention earlier was the observance of a black-like film on the inside of the cooling expansion tank before I took it into the dealer. Obviously dexcool has eaten away at the gaskets.

Now the big question - Will I continue to have problems now that my car has been contaminated? Maybe I am paranoid, but I hear more engine noise (lifters) when I start the car up. Seems to go away when it warms up.

ok i talked to the tech at the shop the other day there is a updated intake gasket out for the 3.4 its not DEXcool its the intake gasket they used in the 3.4

They likely used the same gasket material in them engines regardless its a proplem with the gasket material not dexcool ....look at the DOHC 4.0 in the ford ranger and explorer they have the same problem i just talked to a guy lastweek with a 04 explorer with 4000 miles on it the engine is shot cause the intake casket blew out and antifreeze spewed into the intake and roasted the engine or the newerstyle SH owners who's DOHC engines needed the cam bearing sleves welded b4 there cam went and shattered there engines my neighbour wasnt lucky enough to catch his in time thats a 12000.00 engine oh well get to your local service dept and get the recall work done so you dont have any problems !! and dont pass off all the blame on DexCool till you have the facts this stuff happens everyday!

doode ummm im not relying on what one grease monkey said at all just saying that GM has put out a updated gasket and that this stuff happens everyday but i guess you do have a choice and the brand you use if your worried get a flush and use your own brand i understand that dexcool breaks down the gaskets and i think GM does as well but all the talk about a class action suit is going to go nowhere and if it did we wouldnt see it in our lifetimes

GM sort of pulled through on my Intake problem. After a few letters, faxes and a couple phone calls. I received a telephone call the other day from the GM customer assistance center and they are willing to reimburse 50% of the repair (or about $400), which is better than nothing and puts some form of renewed faith in me. The rep I talked to was very calm and polite, she explained even though the vehicle was out of warranty (50k) they were going to help out in the interest of providing customer service. I am sure this forgoes my claim for any class action lawsuit but at least GM is doing something for me. There is a TSB out on the gasket design.

2002 Impala, 3.4L
3/18/05 @ 56k miles
9 registered trips to 4 dealers in Central PA - still looking for a good one!!

1. Intake gasket @ 52k - thanks Dexcool, $800+
2. Brakes @ ~10k, 15k, 25k, 40k, 50k - warping rotors - $250-350/each time. - had problems all the time, finally the rears were done this last time seems to have fixed the shimmy/vibration when braking lightly at high speeds, I am sure it will return. Front rotors have been turned 3 times now, replacement next.
3. Rear Doors hard to open - still an issue, someone suggested lubing the door seals. Seems the handles are hard to grab.
4. Intermediate Steering Shaft (ISS) - $220 (twice)
5. I had to replace some steering boots - had clunking in wheel when turning at low speed (driveways, stop and turns). Felt like loose brake caliper or popping cv joint.
6. Ignition switch @ 11k
7. And other parts I am sure I missed.

I have not had the “transmission” issues yet and the car seems to have enough power for me, which will be about the time I start looking for a new car. I don’t think it will be a GM.

Pros
- I do like the ride, very comfortable
- Cool styling

Cons
- Repairs, Repairs and more repairs.

One of the reasons I purchased this car (besides the ride) was because I read an article about how the new design and manufacturing could theortically get 400k miles out of the car. I would have been happy to get about 100k w/out any major problems. I fear other cooling system parts will end up going from contaimination. Right now I have a new (redesigned) intake gasket and dexcool running. I don't know if I should remove it or keep dexcool in ~ any suggestions?

I am keeping my DexCool in my engine and religiously flushing and refilling it every 2 years. I also am keeping an eye on the overflow tank so that the level stays where it is supposed to stay. I had my intake replaced back in the summer of '02 and still everything is all right<knocking on wood as I say this> I think with the new gaskets and bolts with sealant should take care of the problem

First of all, I am new to this forum and I think it's fantastic. I have been working on my own cars since '70 and there is a wealth of knowledge on these boards.
My vote is against DEXCOOL. Having to replace the intake manifold gasket at about 65K miles, I changed the coolant to "green". 30K muiles later, I have no problems. I hate the fact that we must pay for poor manufacturing or mis-guidance by the car companies.
My new problems are the "clink" in the steering and the constant AirBag light being on. Suggestions?

Intermediate Steering Shaft, there was a recal on the issue. Airbag light is likely a bad sensor.

I also went to the green stuff, problem is a majority of car owners just don't give a damn about their rides, they think of them as disposable like everything else in the world, sad really.
