How many people know about the problems with DEX-COOL?

[DOC-Z]

I'm asking because I am still flushing out my cooling system after finding I had no heat about 6 weeks ago. Apparently, DEX-COOL degrades after about 5 years or 100,000 miles.

In order to NOT void your auto warranty, I read it should be flushed and changed after 2 years of use. Otherwise, you run the risk of having the Organic Acid Technology ( also known as "O.A.T.") separate out of the fluid and solidify. If you have any sort of air gap, the steam will degrade the fluid and you'll get this muddy, puree'd coffee ground-like $#!T in your cooling system...and it's a barrel of laughs to clean up!

Switched mine to the green stuff at about 20,000 miles. I took my car for an oil change in the winter and the guys changing the oil were flippin out. "Omg who changed your coolant? They put the wrong stuff in it!!"

my buddys shop will flush your system and get most of it out... then he adds a type of coolant that works with all types of coolant - he does it to all his customers with dexcool - its about $130 i think but it beats what you are doing...

Where is your buddy's shop Rodger?

 

[greasy]

Even though I already told greasy but in case others are interested, its the same shop I already pimp out on here all the time... RAM automotive in lake in the hills

 

[Red Alert]

Damn dude that's like 5 min from my house... I'll have to check them out.

 

[greasy]

They are a good shop, had my alignment on my Cobra done there.

 

[Blown 346]

Thats why GM tells you its only good for 5 years or 100,000 miles.....

Dex cool is all I run and I have never had an issue.

 

[Yaj Yak]

I'm with the green crew too.
Flushed out the dexcool shit around 58k when I had the engine out of the car.
That stuff is worse than diarrhea.

that shits no good after 20k

seriously the organic acid coolant should get outta there. it attacks the Orings and plastic parts not to mention aluminum/steel where its stagnant.

ive done plastic lim gaskets on cars with green coolant and its amazing how nice the gaskets look when dex is not reinstalled.

use the propelyne glycol stuff if ya wanna just drain and fill but seriously get rid of the dex.

they didnt run through years of class action lawsuit for nuthin

I have a small radiator leak. I use dexcool, Every month or two for the past few months it gets about a gallon of new coolant (going to fix this over christmas).

Bamn..problem solved, dexcool doesn't get old, my car pisses it out and gets new dexcool. problem solved. lol

seriously.

The owner, Ron, is a super legit dude! He's actually the godfather of my son! I've known him probably 15 years now! They do all sorts of major and minor auto repair also!

 

[Stink Star]

Ummmm we definetly wouldn't void your warranty if you didn't flush your coolant every 20k. In fact, the GM regional managers just had a big meeting in tinley park about GM cars under warranty, basically we are not allowed to sell any flushes or "maintnence" to any vehicle under warranty. Apparently GM is proud that they received the title of lowest cost of ownership and not having to pay for maintnence is a huge part of that

 

[greasy]

Had RAM Auto flush the coolant out of the Blazer and refill, very happy with their work. Good people!!!

 

[Gav'sPurpleZ]

15 years later...is this bad ?
