RE: IML: Smoke on Dash equals Heater Coil leak

["Dick Benjamin" <dickb@xxxxxxxxx>]

You need to follow the instructions in your FSM to get the old heater core
out for inspection.  You should be able to see signs of water leakage in the
housing after you remove the core.  If you don't see leakage evidence there,
take a careful look at everything else hooked to your cooling system,
especially the heater control valve - your leak may be there.   

Take the core to your local radiator shop for a pressure test.  If it fails,
let them fix it.

There is an outfit selling heater cores for old MOPARs on eBay - I haven't
dealt with them because they couldn't help on the special core for the ATC
cars, but they did have one for a standard 67 heater, and may have one for
yours too.  The price might be better than having yours repaired, or it
might not - you'll have to do the research.

I recently had the core on my project 67 tested, and it failed.  Then I
found out that the cars with ATC have a different core, one which is no
longer available without adapting another, much larger core, so the cost of
rebuilding it was quite high, but it can be done.

As many of you suspected, I did find a small puddle of coolant on the
passenger's side mat. Now, who has done this repair/replacment in a '66? How
involved? And where did you find parts? I bookmarked a bunch of ads in
Hemmings, but I also tried NAPA who was no help (and this is a GREAT NAPA
store: always able to find parts for my '62 C*met). I'm hoping this won't be
expensive or the kind of thing where I have to put in something questionable
from a junkyard. Thanks for the further info in advance.
