Hi Robert,

 From you description, it sounds more like thermostat.  If you need to 
limp back to the mechanic, remove the tstat with engine cold, then 
careflully observe temps as you head his way.  New stat and seal must be 
installed where the air vent hole in the tstat rim is at the high point 
of the engine so air bleeds off properly.  You don't say if this 
condition existed before the mech. trip.  You dopn't say if the AC was 
running.  How old are the radiator and visco clutch.  Did the electric 
aux fan ever kick in?
