Where does the HEATER HOSE RETAINER CLIP go ?

[Steve Hafner]

. . . .

My 70 C-10 350 with factory AIR CONDITIONING, doesn't have the heater hose clip pictured below.

Were they only on NON air conditioned trucks or is mine just missing ?

If it's missing, can somebody post a picture of exactly WHERE it goes ?

( does it clip to the fender well ( like some cars do ) or is it just a " clamp " to hold the two hoses together ? )

THANKS for your help !!!

Steve there shoud be a square hole in your inner fender for the clip to fit into.

THANKS !!! . . . I couldn't find any holes in my inner fender . . .

. . . the inner fender IS a reproduction, so they probably didn't bother with the square hole !!!

Maybe someone can post a picture so I can " engineer " a square hole ????

Yup it attaches to the inner fender. Here some pics from my 72

That's interesting !!! The only picture I have saved of one on a truck with A/C shows it just clamping the two hoses together.

There isn't a lot of room with the A/C valve on top of the inner fender.

Where should it have attached in the picture below ?

Oops I didn't read the whole post. My bad. I do not know if it attached to the inner fender on not on trucks with A/C. I have only seen them attached to tye inner on NON-A/C trucks.

After looking around I found this pic. You can see the clamp and that it DOES attach to the inner fender on trucks with ac

Steve there are two types of clamps. One that like pictured is on non a/c trucks, and the second type actually is held in place by one of the heater water valve screws ( the front one, nearest the rad.) and the 3/4 line runs across to the water pump while held by a strap clamp located on the front of the a/c pump.

On my 68 with AC, the clip shown in your first pic is present. It pops through a hole on the inner fender as well.

Yes Blue it is attached in that picture, but assuming the picture is of your blue 72, that is not a factory water valve and the retainer was likely re-located when the heater valve and hoses were replaced and repositioned.

Also, the vacuum pod is metal, my 72 had a plastic one from the factory. I'd much rather have that metal one.

Side note: A/C hoses re-done as well.

This was not a picture of my truck, just one I found online to show a pic of a truck that has ac and that bracket.

That is my 69 3/4 ton in the picture in post 9. I bought it new. I assure you that the clip is original and in the correct location for a 69, the A/C hoses are the originals, and the metal vacuum pod is the original. I replaced the valve in the late 70s or early 80s with the replacement from GM. The heater hoses are not original. The A/C hoses used in later years had crimped hoses rather than clamped. The hole in the inner fender is round, and the tabs at the bottom of the clip are easily spread with a screwdriver to securely fasten it in the round hole. I replaced the inner fenders when I restored the truck and still have the originals. I had to drill the reproduction. If anyone wants a picture of the original inner fender with the location of the hole measured and marked just ask. The 71s and 72s had a different valve and method of attachment. I'm not sure about the which method of attachment was used in 1970 nor when the plastic vacuum pod was introduced. I may be able to locate other pictures if anyone wants them.

OK, now I'm quoting myself. "but assuming the picture is of your blue 72".

Seems we agree on 72s. Nice info, however, on the early models thanks.

I was surprised to see the clamps on the A/C hoses. I thought they must have been replaced. Does your A/C hold a charge and function correctly?

I think I only added a pound of R12 up to 1994 when I stored the truck. Even after that, it would blow cold air when I ran it a couple times a year. Then, about 2006, the compressor started slinging oil so I didn't test it after that. There was still a charge when I had it evacuated prior to the restoration that started in 2010. I was actually disappointed that no one makes clamp type restoration hoses for originality purposes.

It's amazing how many changes were made to these trucks from 67-72. The mechanical and accessory changes, in my opinion, were far more numerous and significant than the visual design modifications. The 69 Service Manual clearly shows the A/C and heater hose routing and clamp type A/C hoses on page 1A-29 including the clip that sparked this discussion. I suggest that O.P. and anyone else interested check their year's Service Manual to see what it shows.
