Don't use dexcool unless it was really cheap; I would use Zerex G-05, that stuff is awesome. its oem in alot of cars and i've had it in my s10 for 4 years after I got fed up with the dexcool sludge despite cap changes and the works.
EDIT: zerex g-05 is a hoat tech coolant, just in case there was any confusion. we're recommending the same thing

are you sure it is dexcool or the chrysler antifreeze cause the color looks the same. (chrysler engineers must have seen the same things i am talking about) i took an engine class through chrysler bout 2 years ago and they stressed not to use dexcool cause they are not the same. gm has been using it since 96 and i have seen a lot of problems. chrysler has used hoat since about 00 or 01 and i have not seen any issues that i would atribute to antifreeze. take apart a gm with the same amount of time and miles and put a chrysler beside it and you will see the difference. we still put dexcool in gm and hoat in mopar but dexcool is job security for me at the dealer.

Dexcool is crap.Dont use it period.Look at some GMs sometime.They look like mudholes.Either use green or we use the new Global stuff that mixes with anything.Two years in the 65 with aluminum heads and still good.I also doubt that a Mopar dealer used Dexcool.Probally the new Mopar stuff that is overpriced.Rocky

We have had water pump failures on our Libertys at work. When you pull the pump there is a ton of pitting and it is usually eating its way through the gasket surface. Our vehicles do get used ALOT though, they pretty much are running 24/7.

I work in an independant repair shop and we see tons of cooling system problems from the newer style coolants, especially dex-cool. Green was fine in all the old cars and it is cheaper so I don't see any reason to use anything else. When you buy antifreeze the trick is to buy a name brand that has the proper aditives in it and use only DISTILLED water, that would be a fool proof plan for coolant.

I've been running for several years nothing but Zerex G-05, 60% coolant/ 40% water, with a 12 oz additive of Redline waterwetter,.......very effective in a hot running car,.....esp wingcars, as they have reduced, and relocated grille openings,........the only problem I have now, is the car runs too cool

The difference is in the additive package. All coolants (besides RV coolant) is ethylene-glycol based. The old "green" coolant we know and love is phosphate and silicate based. This coolant requires frequent service and does have corrosion issues with newer dissimilar metals (i.e. aluminum, iron, magnesium, etc.). So, the OEM's tried to reformulate their coolants. OAT is Organic Acid Technology coolant, and is what GM uses. HOAT is Hybrid OAT coolant, which is what Ford, Chrysler, and Honda use. The differences get very technical, but suffice to say NOBODY wants to use Dexcool in their car but GM. Honda threw a fit when GM insisted that Dexcool was to be used in the 3.5's in the Saturn Vues. Here are a couple of links to articles by Motor Magazine. They're very informative and will answer a lot of questions. http://www.motor.com/article.asp?article_ID=816and also, a more recent one... http://www.motor.com/article.asp?article_ID=938Mark

Is there any problems using Dexcool in our old Mopars? Any advantages or disadvantages? And how thoroughly does the Prestone have to be flushed before switching coolants?
That stuff SUCKS , DON'T DO IT .
I just worked on a car that had dexcool that was supposed to have it , you should have seen the SLUDGE that was in the radiator.
