It's been a few years since I did the research, and I was specifically
trying to get my dirtbike to run cooler. Once I started using
overheating virtually went away (whereas before it would overheat once
or twice per outing). You might do a search on Water Wetter (which, by
the way is made by Redline) to learn the specific science about it.

However (in a nutshell) here is what I recall from my research:

1) Water is a better conductor of heat. That's why we don't run
straight coolant.

2) Water Wetter allows water molecules to make better contact with
metal surfaces like the cylinder walls and radiator. Better contact
with cylinder walls means better heat absorption. Better contact with
the radiator means better heat dispersion.

Now that I think about it, I did not add a lubricant as Water Wetter
already provided that.

Again, I wouldn't bother using this stuff in my Vanagon or any other
vehicle running under normal circumstances. Can you imagine bleeding
the Vanagon system twice a year (at least if you're in a cold
environment like me here in Indy)? Yuck!
