I know, its like beating a . . . , so anyway at the local wallyworld and checking antifreeze. Between GM Dexcool, Prestone A/F and Tech Brand A/F, checking the ingredients, all three have identical ingredients, word for word. So why should I buy the $14 stuff and not the $9 stuff? All say can be used with ANY exsisting coolant.
Thank you for your input. Cool

Hey sorry for not responding quick. Use the GREEN coolant. The dexcool has been known to cause problems(head gasket among other problems.) Flush out the whole block and radiator and use the green coolant with bars leak.

Well, you can't use the green coolant unless you are absolutely sure you flush out all of the dexcool. When the green coolant mixes with dexcool, it sludges. If it was my car, and it had dexcool in it and I was looking to change, I would go with the Prestone.

FWIW, I've had dexcool in my 3400 for over 110k miles. It's only been fully flushed once at around 100k.

Yea I think the head gasket problems are from air bubbles in the engine vs the coolant itself. I personally hear mixed opinions on the dexcool but since I have a old GTO and a old truck, I just use green coolant on all lol

Dexcool never was the problem with these engines. The issue was a cheap nylon gasket that has a tendency to ruin itself in short order...

I use the ready mixed Prestone Dexcool in my cars (mostly because I'm too lazy to mix up my own).

Thanks all, interesting.
Hey Whitelightnin04MC, You say to get all the dexcool out before using the green stuff. The SuperTech A/Ffrom Walmart has identical ingredients as the GM Dexcool from Walmart, and both say they are compatible with all types of AF. So with this info I would not have to flush every last drop out of my car before using new cheap stuff (supertech) which is a lime kinda green.
Although, I would try and get as much of the old stuff as possible, out.
I'm not really trying to be cheap here,just trying to figure out the best stuff to use, if I can save $5 a gallon I will go for that. See my first post on this. Cool

Current Gen DexCool is the same Ethylene Glycol as the old 'green' stuff (and most current mixes as well, however, it has the Silicates removed as they will eat the aluminum in the motor

Older (not sure when) DexCool had a complete different chemistry known as organic acid technology (OAT). This older formula caused alot of the issues when there were leaks in the cooling system or the system was run w/ low coolant.

If you have the older style DexCool in the system flush as much out as possible to avoid the sludge issue. If you have newer DexCool, you can mix it with other universal coolants and you will be fine

Thanks BBE.
I will flush as much as i can from radiator, core, block etc, how can I tell if I have the OAT stuff and do i even need to know? My coolant is a rust color and not very pleasing to the eye. That's why I want to do a flush and get ready for winter, new stat as well. Cool

What's the best way to flush the entire system? While ZZP had my car they sent me a picture of the sludge build up. I couldnt beieve how bad it was. They flushed it for me but suggested I have it flushed again.

Personally I just added water in the radiator and drove it for a few miles then flushed it out. I did this 5 times and it was all clean. I think you can buy some sort of cleaners at auto part stores.

FWIW, GM says not to use any of the chemical flush products - just distilled water. I have good water so I just use tap water in the cooling system.
