Trying to find a video but can't seem to find it... I believe it was by banks diesel they had a coolant pump attached to a pipe into a box that heated the pipe. The heater and pump were set at max and the same for every test. The temperature of the fluid changed depending on what the fluid make up was. The higher the temperature of the fluid the better the fluid was at absorbing the heat from the heater. The used an oil, pure distilled water, distilled water with I believe water wetter or something similar, 50/50 coolant water mix, and a 50/50 mix with the watter. The result was water on its own would boil near the edge of the pipe where the heat was being added and not absorb as much heat, as when it had the wetter substance. It took in a lot more heat than just water. True the 50/50 coolant mix didn't change as much as just water, but it did still improve it a bit. Is it needed, no factory coolant/antifreeze is designed pretty good to be a good coolant and not freeze. But in the test I saw it did improve it slightly... obviously if you want maximum cooling a pure distilled water with something like water wetter will be your best bet.
Also the smaller the orifice the more micro boiling/cavitatstion the fluid would experience in relation to volume so depending how the vehicles internal cooling routing is would also play a significant role
