Re: [DMCForum] Ladies and gentlemen, my (repairable?) evaporator

> So Walt, you see the busted end.

Yeah, I suppose it started with a crease/dent and someone
just said, "WTF" and ripped it out of there?

Mine was in a similar situation from the previous owner.
The smaller pipe was banana-shaped, and the larger pipe had
a crease/crack where it looked like someone grabbed it with
channel-lock pliers.  I had the straight sections replaced.
Here's a link to a photo of it:

If you look close, you can see the repair.

I did not reuse the SS screen mesh.  It's on the output side
of the evaporator where it only holds junk that causes rot.

The black shit is just that.  WD-40 cleans it off.  I bought
more of it at NAPA (comes in a roll), but I didn't use it.
It really should have something around the pipes to seal the
opening in the fire wall, but black goo isn't the answer.

Classic Auto A/C Manufacturing in Tampa did the repair on
mine.  I can't remember what it cost.  I think it was just
over $100.  That included flushing, pressure testing and a
few other things to justify the price.  If you call this
place, be sure to ask them (ask for Al) if they can sell you
a new one.

out, it is worth
running the risk to stick a repaired evaporator back in.

That depends on how much a replacement costs.  At the time I
repaired mine, aluminum replacements were not available.
Now they are.

For a DIY repair, you could probably get a new pipe end from
a junk yard -- it's a common size.  I don't know where to
get an aluminum sleeve.

Now is a good time to use Naval Jelly to clean all the rust
off of the flapper doors, repaint, replace foam, etc.
