Omg Death By Dexcool

[rlith]

Most of the dealerships around here will actually flush dexcool out of new cars/trucks and replace with normal green stuff when they come in the lot. I once talked to the service manager at the local chevy dealer about this and asked about it being expensive for them to always do this, his response?

"We'd rather spend the a few bux per car putting normal antifreeze in, then deal with the headaches of dexcool a year or 2 down the road"

My blazer had decool in when I bought it, 1st thing I did when I got it home (before I destroyed the engine with a screw (see my site for the story) Was do a complete acid flush of the cooling system and replace with green... The rad itself took a while do to all the gel and corrosion..

Granted, if you watch it and maintain it, it will be fine, but most times the crap is more trouble than it's worth...Again, this is only MY opinion. Others may vary...

I perfer the green antifreeze, too.

I just want to stress the fact that if anyone wants to convert over to the green stuff, you must thoroughly flush all of the dexcool out of the system first.

Just wanted to let you guys know, i have had bad experiences with dexcool in my vehicles, but my fiance has dexcool in her 98 malibu and it has 168k miles on it and the antifreeze has never been touched, never flushed, maybe topped off but that has been few and far between, and no problems, so there is a success story for ya! Although I dispise Dexcool!

Nah, I have had no problems with Dexcool in my 1995 Blazer.

The problems that the cooling system had was due to the following:

1.) Parents not changing the coolant until I did in 2002.

2.) After that a rad cap failure allowing lots of air into the system.

3.) Improper dealership flushing. They didn't flush it long enough, one of those quickly 45 minute flushes.

The the overflow tank is filled just below the overflow tube and the air contact minimized, you should have no problems with Dexcool.

Most if not all of Dexcool failures is due to lack of maintanence or a hardware failure.

I also find short trips and city driving VERY hard on Dexcool.

Anyone with a Dexcool system should overfill their overflow resevoir and if you owna 3.4L, you should have the intake gasket checked. Some years had failures.
