Is Dex Cool the devil?

[inkadink]

My recently purchased 1997 Tahoe has Dex Cool in it. I have heard some bad things about dex cool and I wanted to know if I should/could switch it over to the green stuff? What do you all think? Thank-you for any help.

i would switch i run the green stuff after doing a full flush.....im not even sure if you can still buy dex-cool....that stuff sucks anyway my inlaws had a blazer with that shit in it and it burned out 4 heater cores before they realized it was the coolant that caused it. they flushed it all out and run the green stuff and have never had a problem since...

x2, flush it out really good. I did mine twice to be sure I got all the old crud out with a radiator flush from Prestone. Then I used a bottle of Royal Purple radiator additive to ensure proper flow all the time. Think about radiator additives like Gas-X. The Gas-X doesn't lower the volume of air, it reduces it's ability to cling to surfaces, thus passing air out easily.

I have no idea where that just came from....but it makes sense to me?

still in mine, no problems because of the dex after 177,000 Miles.

you must have the good shit....there were hundreds of recalls on vehicles that used dex-cool...thats how my inlaws got there four heater cores paid for

i use prestones gm dex-cool. i think most people have problems because they go by mileage only and not by the amount of years its been in the car. 4 years or 50,000 no matter whats in there.

side note: i have heard some people say dex-cool is harder on cars.

132k with the dex no problems.

supposedly when they brought out the dex, there was something in it that f-ed stuff up inside your engine. if your flushed it out since 2000 your supposedly fine.

Prestone Dex-Cool here as well. it got all new after the radiator split... (plastic crap)
