Heater hoses

[RRMs69Z]

The AIM shows the lower hose crossing over the upper hose for a V8 engine. However, I see a lot of pictures that have a band around both hoses that attaches to the alternator. Which is the correct way to install the hoses?  Thanks.

Drawings are not gospel, pictures are

From my observations: The metal band attached to the alternator was used on the early cars, later cars did not use that band, and I have just seen the rubber ties.
Hopefully Kurt or someone may know when they stopped using that metal band.
Bentley (Ko-lec-tor) is correct, original pictures are best to go off of when you have them.

The metal strap is on my 08E car but it's a 396 so that might be different. One hose comes from the water pump to the forward position & the other comes from the intake & it takes the rear position on the clamp (metal strap)...Joe

Here's a picture back from 1990 of my Z/28 - it has the original heater hoses.   Note both metal clamps - on the alternator and on the inner fender.  04B Van Nuys Built.

Pretty sure all of them have the inner fender clamp, but the alternator clamps I have seen hold both hoses, and it appears in your pic to be holding only 1?

Could be but it's a figure 8 style clip.  This the best pic I have so can't be sure.

Ok, now it makes me think you have the solenoid clip (bracket) bolted in there? Pretty sure that is in the wrong spot.

OK.  Correction!  Found a better image - how's this?  Again, these are back from 1990.  Original heater hoses.  04B Van Nuys Built.

Hmm, that appears to be the right clip, but that also looks like a more recent picture?
I don't doubt your hoses could be original, but that clip could have been added anytime before the 90's.

I went through my pics from guys BITD or buying them new (1969), and I also have seen some unrestored cars. I have seen that bracket in your last pic on early cars, but then at some point it seems they stopped using it. Not sure if it was a big block only piece at that point, most of my pics are of small blocks.

Yeah, I took the picture with a 35mm Camera back in the day and had it digitized.   I'm 99% confident the hoses are original.  70K miles on the car.  Correct "ribbing", clamps, etc.  I still have them.   The car still had the original power steering belts and many other original components.  Unfortunately, the prior owners put a smaller carb and headers on it.

Well the hoses look original. My only question is when did they do away with that bracket? and was it only in certain applications ?

Thanks guys. I would like to know if any one can confirm the picture in the AIM is the way it was done for cars built later in 69.

Knowing the build month and week of your car might help - to compare with another car. Things changed more than once during the model year.

How much later in 69 are you looking for?

My 12D Norwood Z has the clamp on the alternator that holds both hoses, so what is seen in the AIM must be for cars after that date and maybe further.
