Heater Core etc...

I was planning on doing the fan motor at the same time...but unfortunately 
went with the substantially more expensive method of replacing the motor as 
a whole...along with the flap servo (no heat in the winter).  I guess on the 
bright side, at least my fan wheel squeak will be gone (probably could have 
been solved by oil...)  I knew the whole assembly had to come out from under 
the hood, but was getting a bit optimistic that it may not be as bad as some 
have said.  The worst part?  Removing the box from the cramped quarters?  
The firewall seal?  Do I really need two people?

These days the 200 feels like a "hole in the road you pour money into (not 
to mention knuckle skin and time)."  The phrase "good money after bad" keeps 
coming up.

But more topically, if I'm hearing you correctly, this job really does suck 
eggs...and big time?  How's it compare to other major pia jobs such as power 
steering hose, or ebrake cable?  It is doable in a single day correct?
