Hi Tracy,

Here's the data from the Engineering Toolbox.  The viscosity changes a
factor of 4 from 80 to 200 F.  That site has an enormous amount of good
information.

See
http://www.engineeringtoolbox.com/ethylene-glycol-24_146.html
for the whole chart.

Ethylene Glycol Solution (% by volume) 50%
Temp F    Dynamic Viscosity __ (centpoise)
     0           22
   40            6.5
   80            2.8
 120            1.5
 160            0.95
 200            0.7
