so as the story goes I'm installing new heater hoses and clamps there are two versions the Round spring type with two large tangs and the flat steal with three tabs like a fuel line clamp . what is the consensus on witch one is right i was thinking the Round steal was till today . Inline has the other flat type in their book .

 

O.K. I'll bite.
The round spring type with the tangs went up to 68 Maybe early 69.
The flat style with the screw on the side(90 Degrees to it) was from 69-72

I call those the 'tower' clamps. I bought them for my car and they look quite decent. Worm gear clamps are what most people use now unless it's for concours restoration. Those are the same clamps that Fusick sells on page 46 of their catalogue for 71/72 (10 pieces for 29.00) They also list another group as 61-77 application (exc 71/72) for 28.00 for 10 pieces). Now you've got me wondering which is right too.

 

Not sure when they changed to the tower style but my 69 has the round spring style and they are original to the car. I think the resto parts dealers carry them. I don't know if it makes a difference but mine is an air car.

The original heater hose clamps for a 1970 Cutlass and 442 are flat clamps like the the fuel line clamps. The larger diameter clamp is black and the smaller clamp is olive green. No one is currently reproducing them accurately to my knowledge. I have found originals in wrecking yards on Buicks, Cadillacs, and Oldsmobiles.

 

in the 70 AM the photo show's the round type with the tang on them I think they are called a corington clamp ?? Other photos look like the flat ones . Inline does sell the round tang style black for large and green for smaller but they are round. I have other style of order will see what come's

 

lets see them please what part of Minneapolis are you in I work down town 4th ave south

 

I will take a photo tonight if it is still relevant. They look like a piece of metal rod bent in a circle with two straight portions for a tool to expand them. Without the tool they are a major PITA to install. I also have kept the wire style radiator hose clamps on the car which were original to it as well. They look like a standard hose clamp but have two wires going around the hose as opposed to a band. I am up in Brooklyn Park near the river.


Cheers, Mike

 

I have the same ones on my upper and lower and on the stat by pass . yes photo please

 

^ This is what I have seen every time this topic comes up. Unfortunately if you look at the link above on page 85 they list 3 different types of heater hose clamps that will fit 68 - 70 non AC cars?

There is a thread somewhere on here that has pics of the correct clamps as stated above (black and olive) - I just couldn't find it last night.

 

Some interesting reading on this subject.

BTW, I believe that INT has just started carrying the proper style band type clamps for '70 heater hoses, but the coloring might still not be correct though.

 

Good followup on the links. Goes back quite a ways. You and Patton did a great job researching this, and good input from others too!

 

70post is who i was talking to about them . I have them on order and hope they come in by friday I can change out the corbin style that a put on Not abig deal. Thanks for the post vapor I did a search but didnt see that post .

 

I missed the inline tube link earlier but after looking on page 85 my 69 has the clamps that are numbered INL10814. In the description it states that these are for non air cars but I can assure you that these are original to my air car. Might be one of those screwy things that happen on assembly lines. Perhaps the bin of tower clamps happened to be empty so they all got these until someone filled the bin.


Cheers, Mike

 

Yer kiddin with us right Mike?? ILT didn't exist in 69. How long have you owned your car, because if it's not that long I would suggest a PO bought from ILT and installed them. No offence, but unless you bought the car new in 69, you can't validate that statement that they are original to the car.

The first Olds aftermarket vendors I'm aware of were Fusick and Year One.

 

those are the type I have now. The Am shows them also in one of the fig photos i don't have it in front of me but . I do find it funny they say correct for many years on all three types

 

agreed, for 69 and 70 and I'm fairly positive for 68 also. and it doesn't matter whether the car had a/c or not, it's the same clamps on the same size heater hoses. the ILT clamps are closer, but still not right on the money. They have a few things like that. the phillips head screws on the front of the lower fender (68-70, 71/72 have a hex head bolt) to hold the brace to/from the core support are another item where they are close, but still not right on the money.

 

I find these repo clamps to not seal so well. so now in a few instances i put the gates heat shrink black clamps on the hoses,(get them at napa) wipe off the lettering and install the clamp over it for looks. tower clamps are sometimes frustrating. and once they are tight they are tough to get off.

 

this is an example from another car i had, they come in all sizes 65malibu059-1.jpg65malibu050.jpg

 

Great Now we have to move this thread to the non olds section Those are clean looking .

 

Naw...
The pics are just to show an example (heck of a nice detail job too BTW). What kind of finish is that on the rad? It looks like hammertone to me. Whatever it is, looks really nice!

 

Thanks. That is that krinkle/wrinkle finish. I used it on the aluminum radiator and other fittings for that project including the aircleaner. Looked good I thought and durable.

 

100% correct!!!!! I have a couple of original ones, the factory also used them on the water pump side of the heater hose as well.

STeve

 

inlines are a greenish copper look to them for the large one and flat black for the smaller clamp . The flat ones were harder to put on than the round corbin style but they look good . sealed off so far they pulled tight to the point i can see the flare in the hose .

 

If you can, could you post a few pictures of the clamps installed...thanks

 

here are a couple

 

the flat "fuel line type" are one year only for 1970 A body heater hose at both ends, heater core and water pump. check your 70' assembly manual! I have an NOS set encase mine loose tension.
