I just had my radiator replaced and the shop filled the cooling system up with old fashioned green coolant rather than the recommended dex-cool.
Now, I've heard horror stories about Dex-cool. They're either stories of cooling systems filled with sludge or stories of the coolant becoming extremely corrosive and eating the engine from the inside. I've heard that the sludge happenes under normal use, while the corrosion is a result of overheating the dex-cool and leaving it in there, but this is all hearsay. I've been planning to get answers on this stuff and changing the fluid over if I found that Dex-cool is evil, but never got to it. I guess now is the time to look into this.
My 2004 Liberty's cooling system has been fine (86k miles) other than the cracked radiator that brought me to this issue I need some answers on dex-cool:
1) Is Dex-Cool the DEVIL and should the green coolant be left in there as its soooo much better?
2) Should I be worried about trace amounts of dex-cool mixing with the green coolant that the truck was filled with? Should I drain this tainted coolant and fill it with fresh green stuff?
3) Should I drain, flush and fill my cooling system with new dex-cool since that's what Daimler-Crystler did when it was made. Is there a benefit to dex-cool?
