Perhaps "freeze" isn't the best word, even though the manufacturers
themselves use it, but the chart here
<http://www.gi.alaska.edu/ScienceForum/ASF6/680.html>
is a fairly good visual of the temperature:mixture ratio at the point where
the ethylene glycol will not have the proper flow characteristics that it
has in it's liquid form.
