I saw a prior posting that Dex-Cool isn't all it's hyped to be. I checked the Internet and found the bottom line about Dex-Cool is the following:
change coolant every two years no matter what type of coolant you use;
flush the cooling system well when changing from green antifreeze to Dex-Cool;
check coolant regularly for changes in color (due to air exposure).
It's been my experience with my 240 bricks (1 year in two cars) that the temperature gauge is lower since I have been using Dex-Cool. However, I had to change my Dex-Cool after a year in one brick because the coolant changed to brown and didn't float all 5 balls.
Am I missing anything?
