Washing powders and detergents work to make water wetter by lowering its surface tension. As shown in table 1 water has almost 25 times greater thermal conductivity compared to glycol coolants.

What does water wetter do. These products include a unique agent that lowers temperatures by reducing or eliminating bubbles or vapor barrier that form on hot metal surfaces. Water becomes wetter by lowering its surface tension. In addition for cars running straight water waterwetter provides some additional protection. Waterwetter 12 oz doubles wetting ability of water to reduce temps by up to 20f rust and corrosion protection for reduced coolant levels or straight water compatible with all glycol antifreeze cleans and lubricates water pump seals. Part 2 coming real soon. Finally after 300 years of waiting water wetter does it work or do we have another evans on our hands.
Part 1 setting up the experiment and doing the initial test. Detergent molecules are like little tadpoles. This can be viewed by filling a glass over the rim with water or by placing drops of water on a hard surface. With the addition of a surfactant the drops of water spread out and contact the surface more effectively. Supposedly waterwetter also protects aluminum products in the cooling system from excessive heat and cavitation caused by vapor bubbles forming inside the cylinder head and water pump. Dont think your gonna run that 460ci motor with the stock radiator and water wetter though.
The surface tension of water is a force that defines its behavior. Unique agent for cooling systems that doubles the wetting ability of water. This enables the water to carry detergent molecules deep into the fibres where they can come into close contact with the dirt. It helps the transfer of heat from metal to water. Water has amazingly superior heat transfer proper ties compared to virtually any other liquid cooling medium far superior to glycol based coolants. Mixtures of glycol and water have nearly proportional improvement due to the addition of water.
