engine cool additives

[CDIGuy]

does anyone have any thoughts on the use of cooling additives.

I am wondering if I can get a long term benefit to the life of my engine if I use Red Line Water Wetter and a product by Lubrication Dynamics called Diesel Cool.. ( http://www.lubricationdynamics.com/techcool.html ).

It can be 120 degrees on the street surface and in stop and go traffic, I just feel sorry for that poor engine.. Seems like if I can offset the negative effects of anti-freeze and water vaporization, achieving even a 20 degree drop, it has to be good.

I have no low temp fears out here, as a cold day in winter is only 50 degrees.

any thoughts?
