I've seen some alarming reports on various national television news programs
regarding the performance of Dex-Cool. There is currently a class action
lawsuit against GM by vehicle owners trying to recover for damages caused by
this coolant. The programs I've seen have presented arguments both praising
and condemning this product. I personally would never touch it after seeing
the interiors of radiators infected with this product. If you plan to use
Dex-Cool, you should research these claims on your own. By the way, was
anyone else amused by the name of the original poster of this topic?

> Recently other major antifreeze companies commonly

> Dex-Cool is compatible with conventional green or

> I've been using Dex-Cool formulated antifreeze

> (Disclaimer: I'm not recommending any product.)
> About other antifreezes
> There are also some other mixes out there.
> There's Japanese green, Toyota red, Korean or
> European blue, and European yellow.
> These are different formulas from Dex-Cool.
> They are all ethylene-glycol based, but have
> different corrosion inhibitor additives.
> The Japanese green and red antifreezes have no
> silicates, but are very different from U.S. orange
