Careful with this idea.  Ethylene glycol may have a decent boiling point, but 
it has a fairly low flash point(the minimum temperature at which a spark will 
ignite it).  Some brilliant engineers at my company burned down a building 
with milllions in equipment in it for failing to think of this.  Actually, I 
haven't actually looked at boiling point data, but the mixture of water and 
ethylene glycol may become a maximum at some ratio of the two(it might be 
about 70:30  EG to Water).    
   On the other hand, water has the higest heat capacity of liquids, as far 
as I know.  Why bother with the glycol at at?
