does not GM put those seal tabs in the cooling system from the factory?Originally Posted by Reptile
I also dont think its all the stuff people put in their cooling systems as, generally speaking, people are pretty neglectful of their cooling systems. Im sure adding something to fix a leak doesnt help, I agree with you there as there is virtually no way to know if there will be a chemistry conflict in the composition of the products, but I dont think its a leading cause.
Dex Cool itself may not be a 'bad' product so much as it is a bad combo. A high maintenance product (Despite its label) coupled with one system in a car that gets very little attention by most owners.
One of the major things seems to be Dex-Cools sensitivity to air. And then the mentioning of contaminants in a virtually closed system. I would like to know how, in a virtually closed system, I would be responsible for contaminants. Ive pulled radiator caps off extremely low mileage vehicles (we're talking less than a year old) and there had been dex sludge in quite abundance on them.
Im not picking Reptile, just kinda contesting what you are saying because I see things a bit differently. You certainly have an inside track on things. But the information I have read over the years certainly doesnt say that DexCool is a 'bad' product but it is far from being as good or equivalent to anything else out there.
