I am in the process of storing an entire front water-cooled heating
unit from a 91 GL and was wondering what precautions I should take
with regards to flushing out the front heater core and cleaning it
before it sits for a long time(I hope).  I would not be normally all
that concerned, but the stuff I drained from the radiator left some
to be desired.  There's clear water running out from it now, but I
wonder if I shouldn't heat up a few gallons and use some radiator
flush?  FWIW, some one has opened up the heater unit making me wonder
just what kind of condition the blower motor is in.
