Victory over the heater core
« on: June 10, 2012, 12:08:11 »
Has anyone on the committee of management of this group given any thought to printing a  "T" shirt emblazoned with "I removed the heater core from under the dash and still had a functioning back at the end of it".. ;D

Those posts from some time ago which claimed that the Pagoda design team started with a blank piece of paper, drew the heater core then added the rest of the car weren`t far off.

Luckily, when i got it out it did have a leak so all was not in vain. Still, an extra session of Pilates this will help my core strength.

All the sealing felt has deteriated; any modern substitute?

Cheers

Been there, done that!
Just had to get a bracket re-soldered on one end.

For the sealing foam, search the forum for "mcmaster".  Alfred posted to the forum what he used, I used the same based on this recommendation and it seems to work just fine.

"McMaster-Carr [http://www.mcmaster.com/] sells high-temp  polyurethane foam sheets  - but you'll have to settle for charcoal/black colors rather than light blue.
I have used 1/4" thick foam, item # 86115K21 (up to +225° F) and it seems to work well.

The Classic Center uses and sells a foam material. They sell it in a large piece (meter^2 for $10 or $20 if I remember correctly).
I also used a Mercedes glue (very similar to rubber cement) to adhere it.
Used the foam and glue on my blower unit and distribution box too.
Count me in on the T shirt.  ;D
I can provide part numbers in a few days if needed.

Iconic,

Yes, please provide the part number of the foam if it`s not too much trouble.  I can`t find it in the EPC.  In fact, I can`t find any of the foam used for things under the dash.

By the way, McMaster-Carr, which I used regularly in Michigan, doesn`t sell to Canada, if I remember correctly from the last time I tried to buy something.  There is another one whose name I can`t remember who doesn`t sell retail here.  It makes it difficult to "make-do" in the absence of reproduction or original parts.

Thanks,

Tom and all,
Please note: This is NOT the original material, but it is the material I was told the Classic Center uses in the following applications (see pictures).
The foam: 000-983-12-98-9015 (enough material to do a lot more than one car)
The glue (like rubber cement, but I don't know what other properties it has and I want do things only once, so I figured if it was good enough for them, it is good enough for me.): 000-989-92-71 (the glue is expensive, but I don't like to take chances or experiment)

I also used the foam on my heater core.

You might want to check out a product called Dynaliner.  It is a very high-quality foam with an adhesive backing.  Comes in 1/8 and 1/4 inch thicknesses.  I used it many places putting the heating/ventilation back together on my 280 project.
