[TR] water wetter

[spook01@comcast.net]

Water wetter acts by removing surface tension, allowing the water to "stick" closer to both the engine insides (reducing spot hot areas) and the radiator tubes.
Thus, the water absorbs heat more efficiently, and passes it to the radiator more efficiently.  Thermostat action is not effected.

ISTR the claims for water wetter are to aid in the transfer of heat. I doubt
it ever could show up as the coolant measuring a lower temperature because
that is managed by the thermostat. The t-stat is going to open at 160, 180,
185 or whatever temperature yours is set for, regardless. So if the water
wetter actually worked and sucked that heat out of the engine components
faster, all that would happen is the t-stat would open sooner and allow the
coolant to circulate through the rad. Again, if it is doing it's job, the heat
would have to be given up more readily to the fins in the rad. Does that make
sense?

In order to gauge whether the water wetter was having an impact, wouldn't you
have to actually measure the engine temps (not the coolant temps)?
