Redline Water Wetter

[Steve Albrecht <albrecht@xxxxxxxxx>]

I am confused by the marketing hype of Redline's Water Wetter.  The
label claims that it will lower the temperature of the cooling system
water by some amount, 10 degrees or something, I don't have a Water
Wetter container handy so I am working from memory (poor as that may
be).  Can someone with some chemistry background explain how this
works?  My understanding of the automobile cooling system is that the
coolant temperature is controlled by the mechanical/thermal properties
of the thermostat, not the chemical properties of the liquid coolant. 
So is this stuff snake oil or what? 

Thanks
