Coolant Confusion

I suggest all Saturn Owners, particularly Vue owners with the Honda V-6 read the following article from Motor Magaziine:

"The questions about 2-EHA were raised not only by Ford (and reportedly DaimlerChrysler) but within Japanese coolant development circles, as well. When Honda introduced its long-life coolant, it specifically excluded 2-EHA, and we can tell you there is unhappiness at Honda regarding DexCool in the new Saturn VUE with the Honda-supplied 3.5L V6. The system is being filled with DexCool because that's what's in the plant for everything else. It would not be simple to set up a separate coolant fill system for the Honda engine."

The part I didnt like is the "Replacement parts" section. You never want to use copper in a system that has aluminum. It will act like a mild battery and could ruin your system.

This is the first time I've ever see 2-EHA mentioned! If I do a search in google for 2-EHA + coolant I get only 4 sites. They've also done a good job on explaining the "rust" issue. I've never seen a Dex system that look bad if it was kept topped off. I will still continue to use dexcool and dex compatible coolants myself. There isnt a better coolant in our market as of yet from what I read. They didnt make it clear if Prestone or Zerex contains 2-EHA though.
