I'm trying to think how water wetter will reduce coolant temperatures.  I 
suppose it improves heat transfer from the coolant to the radiator tubes but 
won't it also improve heat transfer from the head and cylinder walls to the 
coolant also?  That being the case it will improve the cooling of the head 
and cylinder walls but that isn't what is indicated by the temperature gauge. 
 So maybe there is a benefit that just doesn't show up in the gauge 
reading.  

Or not.

I've also been told that antifreeze has additives with the same properties 
so adding water wetter to a water/antifreeze mixture is redundant.  Racers 
use water wetter because they run straight water - track regulations.  

But I agree, there is no snake oil alternative to a healthy cooling system.
