First off, I don't lie!!!! I personally never take my cars to the dealer because they rob you blind and do lousy work, If they still are using it then my appologies for any inaccuracy, my information must have been wrong and perhaps i was mistaken on that one point....did you even bother to look at the links i provided?? especially the first one...so since I'm lying i must ask then, what is the brown sludge that is found only in cooling systems that use dexcool??? and why did gm settle a class action suit if nothing is wrong with it??? and why does every intellectually savy mechanic I know firmly oppose using dexcool??? In my research i have found only a couple people that say dexcool is fine,(with you it's 3) but that number is vastly multiplied by those that have had problems.... In my opinion dex is garbage, i will never use it and will flush it out of any vehicle i may purchase that has it inside....so to each their own....Originally Posted by Sabrewings
Total lie. I worked for a dealer and it's still used to this day. It's even used in the Corvette ZR1 and is now used by other manufacturers than GM. The brand new Malibu my girlfriend test drove the other day had Dexcool in it. Said so on the cap.
Dexcool has problems in our cars because our gaskets from the factory suck. If there were no leaks in the coolant system (even small leaks you can't notice), it won't do that. That's why the only cars that have trouble with it have leaky gaskets, and what's even funnier is that people blamed Dexcool for the gaskets too..
Dexcool is not the problem if it's forming deposits. You have issues elsewhere and Dexcool is reacting with it.
Point is that plenty cars are out there running Dexcool and will never have that problem. So how can it be to blame?
with that said, does anyone know the proper flushing procedure??? i checked the write up section and found nothing, if anyone knows maybe they could put something together.... I usually just pull the bottom hose and drain, the drain plug has a wierd fitting that takes a tool i've never seen before.... maybe it requires a "DEX TOOL" hahaha lol....
