It took me longer than expected, but I did manage to complete the Durango   
   repair today.     
      
   I replaced the auxiliary coolant pump and the "Y" style heater hose that goes   
   to both of the heater cores.  Had some trouble getting the one feed   
   disconnected that went to the rear heater core.  It was behind the front   
   passenger side wheel well.  Had to take the wheel and half the spash shield   
   off to to get it.  Had to cut the old one off.     
      
   Then the fun of routing the hose around all the stuff and clamping it in   
   really tight places.  Everything seems to be fine now - had to add 2   
   containers of antifreeze to re-fill it.  Also had to "burp" the system by   
   taking off the bleeder screw.  It will take awhile longer to get all the air   
   out of the rear heater core.  Most of the air is out, but I figure it will   
   take some daily driving to get it all flushed out.     
      
   The heat is working and there are no leaks, so I consider that a success.   
      
   The rain held off for my work, too.
