Has anyone tried the WetWater to reduce the water temp in the radiator? I've seen it advertised but I don't know on anyone who has used it.
Thanks

On three different cars I have not seen it do any good. One of which was during a long drive in a last minute attempt.

I believe it's primary function is to allow you to run a higher percentage of water (less anti-freeze) and still keep the pump lubed well and also prevent inner-block corrosion.

It's no miracle cure, that's for sure.

I threw a Gunk product in, Cool it, Very Cool, something like that. Comes in a big "oil can". Dropped temps in my app.

I don't know about "wetwater", but Redlines Water Wetter does work. It is good for 5 to 10 desgree drop. This was done with 2 $8 bottles of Water Wetter in a stock 4-core radiator with 95% water 5% antifreeze with a 468 BBC 3 years in a row. This was a controlled test to confirm it the first time is tried it.

Will be testing to see if it works with my new aluminum radiator after another week of baselining without it.

WaterWetter and like additives do not necessarily drop temperatures as they claim. These products are super surfactants that make water/coolant quench better and void air from the coolant and prevent hot spots and air entrapment thru lower surface adheasion properties.

Usually, if you add a surfactant to your cooling system and see a temperature drop is indicative of air entrapment that was present and the additive changed that situation.

The surfactants will also cause the coolant to absorb heat at a faster rate, but not improve the overall capacity of the unit to carry heat. What this means is if the radiator will remove the heat and you can increase the flow, the result will be a increase in capacity of the system in general.

Most cooling systems DO NOT NEED LUBRICANTS. So, they really don't serve a purpost there. But, they are good insurance for the system and that alone makes them worth the price.

If you add WaterWetter to a properly designed cooling system it won't help one ioda! WaterWetter is not an anticorrosive agent that I know of. Different set of additives.

My brother had a chevelle that never went below 200 degrees... had the standard 50/50 mix of anti freeze and water... put one little bottle of waterwetter in it and its never gone above 190 ever since... I dont beleive in miracle cures in a bottle, but i will say that i beleive this stuff really did lower his temps, and he runs lots of antifreeze too, which many people says nullifies the effectivness of the water wetter... try it, you just might be surprised.
