Bill,

That hose being shredded would account for a good deal of your overheating 
condition.  On a non-AC car it would be by #5 cylinder.  I'll assume that 
Tim is correct when he says that it is by #6 on an AC car.  Either way, if 
you have essentially an open hole (non-connected or shredded top side hose) 
a large portion of the cool air which SHOULD be passing over the head and 
cylinders is escaping and NOT going where it needs to go for engine cooling. 
It is a good thing that you found this and were able to replace it.

You mentioned the size as 4 inches, but as I recall that is a 3 inch hose 
which has to be flattened into an oval in order to go through the steel 
backed rubber grommet in the firewall.  The lower ones are 4 inches and it 
is also good that you found the one dragging on the half shaft since they 
have been known to (in effect) saw the half shaft to the point of failure. 
For the 4 inch ones, DO NOT use close dryer hose as it cannot take the heat. 
Also, the original style had a metal wire inside which CAN possibly cause an 
issue with shorting on the starter and burn your car to the ground.  The 
modern ones from the vendors have a stiff plastic coil where the wire coil 
used to be.  Use those.

Oh, when you "removed" the condenser, you did not disconnect any hoses from 
it, right?  You just set it to the side with hoses attached I hope.

I'll be away the rest of the week, so don't know if I'll have internet 
access.

Later, JR

 I got the heads pretty cleaned up, then I (innocently) proceeded to attempt 
to replace the "fresh air hose" that runs from the front (behind the rear 
seat area) shield to the top of the turkey roaster. You know, that funny 
rectangular hose. Since the A/C condenser is blocking where the hose comes 
into the engine, bay, I remove the condenser. The original fabric hose was 
torn to shreds.

 I kept following it until I found the plenum where it attaches. I removed 
the metal lip that holds the rubber seal in place at the front of the engine 
bay, then reached under the rubber and worked for a couple of hours, but 
finally got the new hose on!

But I do see a light at the end of the tunnel. New accelerator boot (old one 
torn), new "fresh air" hose, new carb gaskets, and new heater hoses (both 4" 
hoses torn and unattached, one dragging on the half-shaft) and lots of 
cleaning, eventually I hope to get it all back together.
Good night folks, I'm tired and my wrists are cut and sore from getting that 
hose one...Bill Hershkowitz 66 Monza 110 PG A/C
