Has anyone done any "real world" testing to determine if any of the numerous performance coolants or additives such as "ICE" truely lower engine temps in comparison to standard Eythlene Glycol? My wife's 05 Polaris 700 EFI (I know...the wife's bike??? she picked it out!) and it has boiled over twice. Why we are on the subject.... I have never had a over heating issue with my WR even though it is here in AZ. Anyone else ever overheat a WR? I am not concerned with mine.
