How much antifreeze into my AWIC?

[douglas vincent]

Title says it all, do I run the same as my radiator? Getting cold here/

Yes. 50/50 should be fine. Less if you want the minimal increase in efficiency. If it freezes up, at least it won't ruin the motor.

might want to run water wetter as well to improve the efficiency of the system. The water wetter reduces the surface tension between the water and metal, and improves heat transfer.

Let me find the name of the stuff I'm going to use when I get home. It's kind of expensive but won't boil anywhere near the temps an engine runs at. When it freezes at like -40 it turns to a slush and doesn't expand. Oh yeah and it has better heat transfer than coolant.
Like I said cool stuff. That said I've been running about 50/50 of the regular stuff.
