Hello All, a newbe here

[dmbrisket 51]

hey dont feel bad, i wasnt thinking about it and put green in with my dex one day, it lead to buying a flush kit (<$5) 2 gallons of dex ($20) and then a water pump, $46, only because i get a "prefurred customer" discount, otherwise the pump is 86... it wasnt my smoothest move

There is no difference in the gasket materials used from 10 years ago to today in our trucks... There is no difference in the materials used in the radiator materials, seal materials, etc. To say green will eat through a core (rad or heater) is just plain BS. If that were the case every old truck would have an over heated motor. Dealerships wouldn't swap them out and continue to provide warranty.... Dunno what yer smokin man, but I want some!

I know a number of guys that have changed from Dex to green. No problems years later and they are really happy with the change. Chevy didn't change anything in there motor's with dexcool engines, they just thought it would be better for aluminum blocks. As Chevy found out, and we all now know, Dexcool really sucks and can hurt an engine if not watched.

I was reading my Haynes manuel about this. It recommends using dex cool. That is what it is designed for. The only thing it says is not to mix the two coolants, i dont remember it saying that the other coolant is bad for it. If you are really set on using something else then flush the other stuff out first. It will screw things up if you mix the two... Why not just use what the manafacturer says. Wouldnt that be the easiest and most logical descision?

[rlith]

Isn't that what I said in the 1st place? I never said mix the two, I said flush, then change.

[chris15706]

Yes i was agreeing with what you said to xtrememeasures10. I just added to your response. I was just saying that maybee it would blow up or something if you mix the two.

[dmbrisket 51]

if you mix the two it foams up, kinda cool looken, but really bad on the wp and internals

[chris15706]

Sweet. Im gonna try it on someones car i dont like....

No reason to go to green on a system designed for Dexcool.

Dexcool is not the cause of the sludge, the bad stock rad caps are.

Well I didn't mean to start the orange/ green thing, but thanks for all the input. Here is what I will be doing, once the outside temps get above 35. Back flush the core first to get flow back, then a clean and back flush of the whole system. I will be adding my signature hose ends to the heater hoses. A new Stant 10230 has been purchased. Now for the anti-freeze, since I like the girl friend I sprang for the $9 a gallon stuff. But not Dex-Cool, it's getting Peak Global. Call it yellow and can be mixed with either my old green or Dex-Cool. It meets the GM spec 6277M and this way down the road, in a pinch, it could take a shot of green. This is the second S10 she has owned and it drives alot nicer than her last one, that was a 91 4.3. Here is a picture of my everyday beater

Tell them blazer. This dude on here doesnt wanna believe me. but do what ever you want go ahead n put green in there because a mechanic or customer service person said its ok. They dont know jack. An ENGINEER DESIGNED THE SYSTEM. not a mechanic. The engineer knows that if you put a highly corrosive substance in a system that is designed for a non corrosive substance its going to corrode. Now come on thats day one stuff. I stand by my post before and just like blazer is tellin you. Dex is not bad. switch your rad cap and you'll be cool. Or go to green at your own risk and end up with some major problems.

So do tell, what was engineered between 92-current 4.3's that's radically different in the cooling system? Hmm, gasket materials? Nope, Radiator construction? Very little redesign, same materials. Block? Nope, freeze plugs? nope, still aluminum (why they didn't use brass is beyond me, shrug), so tell me, in what oh so special way was the engine specifically designed for dex-crap?

its all about the mighty doller a doller they screw us out of by useing aluminum instead of brass is a doller in their pocket

[BlazerLT]

The base fact is that there is NOTHING wrong with dexcool.

The problems have come about mostly due to poor rad caps and poor maintanence by drivers.

Modern Engineeres aren't like in the old days when they had to know the trade before they could design crap.

Look at all the plastics designed to brake right apart after so many years, and all the polution control junk designed to make our cars burn more fuel, and not perform like they can. How can a car that burns more fuel be better on the enviroment? It can't It's just better for those rich gas companies
Not to mention remember when you could fix any car with a basic wrench set, and a test light.

For every 1 thing that an engineer does right, like Dex they probably do 10 things wrong, and this won't change until engineers have to swing wrenches for 6 months out of every 5 years that they design cars, and they stop taking payouts from the big companies
