68 Air Conditioning -Sealing

Mark,

No holes, but I'll have to look about dimples...
It's going to be over a week before I can get to the car.  I have to work all weekend to help pay for the toys.
Thanks for the info on the glue.  I've actually got a tube of the same thing.  It's worth knowing it stands up under the heat.  I still think I'm going to glue my AC seals.  For my build date, that seems to be correct.  If it comes off after a while, I'll go back and clip it...
Thanks!

..Now, if anybody knows a source for the clips, let us know!

I've seen the same clip on the cowl seal on impalas and i think chevelles  . other cars probably have them .

[lakeholme]

One other question: How is the core seal placed so you can get at the bolt that holds down the support bar on the battery side?  ...If it is glued?

[mark x22]

the seal covers the bolt if you glue it you cant glue that area . can you scan and post your 1968 AIM page that shows the seal and glue ?

[lakeholme]

Mark X22,

Thanks for the help.  The bolt access is another good reason why they went to the clips, I suppose.

Sorry, don't have a scanner...

The 68 AIM clearly identifies the core seal (3937126) in the diagram as note #1 and the radiator seals (3937127-8) as #2, and each is coupled with #10 which states "Remove backing for installation".  That's how Ed established the process for gluing the seals.  The date for that page is 11-3-67 (C60/B3) and it shows no revision record for that particular page.  (Note his June date above for the last revision of the 68 AIM.)

If Ed happens to see this page, I think he has a scanner.  Help, Ed!

Hope this is of some help...

Well, I tracked down a core support seal --glued it-- and here's how it turned out:



I did leave myself (unglued) room to get at the support bar bolt to remove the battery.

From Mark's post above, I realized that the baffles aren't an issue on my 68 12D (when you look at it you can tell.)

Now, I'm looking for for material to make those top seals like Markx22 suggested.

Thanks for the help!

Phil,

That looks really good. What kind of glue did you use? (Hopefully it's heat proof!!)

Is this the scan you were looking for?

Ed

Thanks, Ed!  I really do appreciate your opinion.
I used a black 3M glue, which (I think) is either the same or similar to what Markx22 mentions above.  I did try a test strip of it with the motor warm.  Didn't seem to phase it.  He says it has held his seals for years.
Yes, that's the AIM page that Markx22 asked for. (I need to get a scanner!)  Thanks!

I did take the time at the Charlotte Autofair to track down a well restored 69 without A/C.
So, here's a dimple (I presume), and my 68 doesn't have them...

[lakeholme]

I also tracked down a well restored 69 with A/C.
Here's how this guy did the seals:

It does have clips.


I could not tell how the 3937127/8 seals were glued --if they were.  It was a very clean job... nice and tight, and I didn't want to pull on them.

[mark x22]

i used 3m weatherstrip glue on the radiator where the seal sets on the top plate .

[lakeholme]

That's good to know, because that's exactly what I've got.  It is working fine on the core support seal.

3M yellow glue WILL fail after a few years - both ends of my seal are loose. I think I installed it about 10 years ago. NOT correct for a '67 but mine had cooling problems and also blew an a/c hose so it was a fix that seemed to help.

The glue we are talking about is not a yellow glue.  It's more like rubber cement. But I do thank you for the info.
I've literally looked at dozens of these now.  Apparently the original glued seals did come unglued at the ends, etc., originally.  That may be another reason for the clips.

[rod67ss]

At the time the parts store said that the yellow weatherstrip adhesive was superior to the black. I'm not sure if he was right but it sure looks worse if any gets out past the seal! And you're right it does work like contact cement so "glue" was the wrong term.
