How can I improve heat transfer/what are alternative coolant fluids?
Redline sells a “wetting” agent calleed “Water Wetter” as an additive that improves heat transfer. It comes in two forms solid (discontinued), which contains phosphates, and liquid w/o phosphates (OK). People who have used it can’t tell any difference under normal driving conditions, but it does make a difference if the problem is that hot spots in the cooling system are causing localized boiling Under normal street use you will not see any change because the thermostat is regulating the temp. It’s only when you exceed the capacity of your system and the thermostat is all the way open that the wetting agent will have an effect. The wetting agent is supposed to improve heat transfer by reducing surface tension. This is important near the head where the coolant my locally boil. The little gas bubbles however impede heat transfer, which in turn may lead to knocking and reduced engine performance. Redline claims it can reduce engine temp by as much as 30F (depending on the antifreeze /wate
