Default 82 Radiator Seal Installation Help

All,
I'm trying to get an 82' core support and radiator installed in my 69' Coupe (for an EFI conversion).
I have the core support installed and I have new radiator seals but I do not know how these are supposed to attach for an 82.
There are 2 long seals and 2 short seals that came in the kit.

Does anyone either have a picture of an 82' with the radiator seal locations or perhaps a page from the 82' AIM that shows the correct placement?
Any information would be most appreciated.
Thank you!
Elm

My radiator seals are long gone but I've never felt the need for them. Therefore I've never thought about where they are installed or what their purpose is. I always assumed they were there to ensure that all of the air being pulled by the fan finds its way through the radiator which says to me that they would be between the rad and the shroud. From the diagrams here though, it appears they go between the rad and the rad support. What is the purpose of that?

GM sealed this area very well so that almost all of the air that is being rammed into the radiator actually goes through radiator and does not go around it. Due to the radiator being at an angle and all of the seal that seal the hood to the radiator support area and so on. GM did not want the air that would hit the radiator to go between the radiator and radiator support.

I know many people who do not care to put them in. Many of them do not have a heating issue ...whether it is at idle or going down the road. While others do have a problem.

But all of the components GM installed to provide the most air getting through the radiator were put there for a reason.

Now if you live in a cold climate...then it may not matter...but if you live in a hot climate... TRUST ME..all of the components GM installed...if installed... can help.

Default Seals too thick?

OK, so I installed the new radiator seals per the AIM but how am I supposed to get the radiator in with the seals so thick?
The seals were from Dr. Rebuild so they should be correct but I don't see how I can wedge the radiator in place without collapsing the tanks (aluminum Radiator).
If you look at the attached photos, you will see how thick the side seals are in relation to the bottom cushions. These seals would need to be compressed quite a bit to get the radiator in.

Is there some sort of 'trick' to getting these in or do I need to cut these seals thinner?
Any advice would be most appreciated.
Thank you,

It is hard to tell...but I think the vertical ones are not in the correct place and turned 90 degrees.

I do not use Dr. Rebuild seals so I do not know much about them and I can not tell if you had to apply your own adhesive or if these seals have an adhesive strip on them.

I would be more concerned that the aftermarket aluminum radiator will fit correctly and THEN deal with the modification to these foam seals.

The radiatior fits perfectly- That’s the first thing I verified.
The seals on the other hand....
They come with the self-stick adhesive already in place so there really is no option to install them on the wrong edge.
Looks like I’ll be removing the core support and trial fit everything on the bench. Who would have though some foam strips could be such a big pain in my backside..

regardless of where the self-stick adhesive is, all you have to do is look at the diagram, you can see the wrong side has been used.

The wrong thickness has perhaps been used but the side that is attached to the core support is correct-
There are cuts in the seals that allow the seals to curve at the top to conform with the core support. Those are all in the correct locations.
It's the thickness of the material itself that seems to be off.

Then if all is as you say it is....I would cut the new seals to the width I need...especially if the tanks on the new aluminum radiator are different than the factory radiator.

From what I know about these seals they seem to not be correct as previously mentioned. And I know that have been cut so they can bend as you stated...but that does not mean that they were messed up from the start and they were made incorrectly.

I would not loose a second of sleep over this....I would cut them to the needed width and move on....only because I have had to do just that in the past. These seals are seeming to fall into my "95% rule" category.

No seals installed when I put a new generic aluminum radiator in a year or more ago. Maintains spec temp in HOT Houston heat without them. Maybe I am one of the lucky ones that do not need the seals. Not going to take the radiator out to add seals that are not needed. Thought about buying some pipe insulation from Lowes/Home Depot and feeding it down the sides. Not done yet.
