GM Dex-cool
Has anyone heard about the class action lawsuit by many people nationwide against GM and others concerning Dex-cool coolant causing problems, like leaking intake manifold gaskets and overheating. I was at a local radiator shop having a friends radiator flushed and he handed me an article about it. This was the first I had heard about this and was wondering what any others may have heard.

I have Used dex for many years with no problems... But the makeup of Dex cane become acidic not helping the gaskets...
I currently have Prestone Orange OAT Coolant which is compatible with Dex... I would have bought Dex but they didn't have any on the shelf...

My 3800 II runs dex-cool, I have not had any leaks yet close to 90K miles, but it is not a nice thought, since so many HAVE had problems.

It created a bit of a mess, more so I think because there were air pockets in the system... There was some of that nasty gooo built up in the system... I made her take the car down to the dealership and have a full system flush performed and refilled with Dex... I told her to never mix the green coolant with the dex... I told her to make sure and add a coolant that said " Dex Cool compatible " on the bottle... Been a few years and she has had no issues... Her son( my good friends brother ) now drives the car and to date he has had no further issues..
Ran it for several years in my 95 ( 6 years ) with not a single issue

Dodge uses a similar Dexcool coolant. Took the Caravan to have the oil changed; they topped off all the fluids. Although the reservoir had a giant warning label to not add regular coolant, they did. It also created a mess and the coolant turned into sort of mud. The van started to overheat and it cracked a cylinder head with only 6,000 miles in the odometer. It was a big event to make the shop repair the van until they were legally threaten. They wanted to just replace the head gaskets; I had them replace the whole engine with a new unit at the dealership.

And I agree... At 6000 miles I would have been demanding a new engine too... I guess us car guys don't have those issues as we know not to mix certain coolants, and we understand what can result if the two are mixed or the system is run low... No one should ever let the system run low in the first place...
Glad you got them to fix it tho..
