C3 1969 350 w/AC heater hose routing

[Jimmy B.]

How exactly does the heater hose route to the cast iron intake manifold?

My car is a 1969 350/350 with factory air conditioning (C60).

In the AIM UPC C60 sheet D4 (yes Jack I do own one of these) it shows the heater hose coming through a bracket at the lower front of the ac compressor (this was missing off my car but I now have one), yet I see photos in some well known published books of what appears to be a heater hose looping over the top of the ac compressor then going down to the intake manifold heater nipple and not going to that compressor hose holding clip/bracket at all.

I bought a hose set from the Dr., 1 hose has a 90 bend at one end and straight at the other (the bigger 3/4 one), the 2nd hose (smaller diameter of the 2 has a bend at each end).

Does anyone have a "decent" drawing or more detail oriented picture they can send me or post?

Does this hose have a bend at then end or is it just straight?

Lastly I bought a hose clamp kit I have 1 1/8 in. and 1 1/16 in. clamps, which one goes on the intake nipple and which one on the heater control valve?

Thanks for your help on this. Might make a good article for the RESTORER.

Regards,

Jim Blakely

Jim,

I also have a 69 350 350hp with AC. The hose that runs to the intake manifold runs right behind the AC compressor and attach's to the manifold with the bent side of the hose. The other hose goes to the water pump and runs through the "bracket" under the front of the compressor.

As far as the clamp size I don't remember the size.

If you still need a picture let me know and I 'll try to post one tomorrow.

Now, you're going to 'enjoy' the fun of actually getting the hose to route through that lower clip, Jimmy! Hint: consider connecting the hose, loosening up the upper clip fastener, removing the lower clip fastener altogether, then 'swiveling' the clamp to capture the hose and finally installing and tightening the clip fasteners...

Once you execute the job, you'll come to understand why so many cars have their hoses routed in non-factory standard configurations!

I know there is differences in heater hoses for small/big blocks. I might be mistaken but if I remember correctly the molded bends in those hoses you spoke of are used for big blocks with AC.

If my memory is correct, there's no difference between SB/BB with respect to AC heater hoses in this era. The reason for the molded, right angled, ends flows from the geometry difference in inlet/outlet nipple construction at the Harrison air box vs. that of a non-AC equipped car...
