I am still on my orginial factory fill dex cool that is coming up on 5 years, and I want to get ready to swap it out. I have only seen two brands in stores here, Prestone and Havoline. Then there is also the dex cool from GM dealers. Anyways I remeber seeing a comparison chart somewhere before comparing the different dex cools out there, and I remeber seeing that one of the two prestone or havoline did not do all that well and said it was more prone to cause corrosion in systems. Maybe you all might have seen this before but I can't remeber where now.
Anways, which one do you all think is the better to use? Thanks for any help
