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.
