[C320-list] Hoses going through the wall

[Jeff Brown]

Art
Yes, I re-glassed the bottom of the muffler and it doesn't leak now.  I'm telling you, I've checked everything and been battling this for a year.  I gave up on it a while ago, because my wife said I was going crazy.  I just didn't let it bother me but for some reason it does, and I'm again on a mission.  My plan is to do a very detailed process of elimination on the cooling system next.  Did this once before but before I really confirmed it was the cooling system, and this time, I'm going to have a second set of eyes and brains on it.  We'll see.
Best regards,
