Red Line Water Wetter

Shannow actually theres a little more to it.... if you keep in mind how the typical liquid cooled automotive engine transfers heat to the operating environment.Of the heat not going out the exhaust roughly 30% is actually handled by the radiator.The rest is radiated by the block,heads intake manifold and everything else attached to the engine with the exception of the exhaust manifold(s).(The oil is the bigger mover to the pan)In practical terms the larger effect of any surfecant is to increase the transfer of heat to the outer surfaces of the engine assembly.As to actual outlet temps..... well that depends.Keep in mind that most people aren't measuring coolant pressure and that not all temp. sensors are located on the t stat. housing. There is the general case and a couple of notable exceptions.Also the particulars of the coolant mix and the condition of the system matter a great deal.A really big factor not often discussed(esp by those selling the product) is the effect of operating pressure and if there are any really hot hot spots in the engine.Then theres the dance between these two.... Assuming a nominal system on a normal day at full operating temp you will see a larger temp. drop across the radiator and a lower radiator outlet temp.And then in some applications ...well its just real interesting to be looking at some other temps too.Bottom line I like all the secondary benefits as much as anything else.
