Where to find a heater core?

Where to find a heater core? - 03/05/13 10:05 PM

I need a new heater core for the Imperial. It's a twin core unit similar to this:

The radiator shop I use is a great place that has been around since the 40s. They usually find anything I need. This time around they've drawn a blank. There are apparently no 1972 Imperial heater cores to be had.
They tried ordering similar size cores that could be modified to fit my car but there are none available in the correct width.

The cores measure 8-3/4 x 6-3/8 x 1-1/2. Custom cores could be made but I'd be facing $400 or more.

Do you guys have any idea where I could find heater cores?

i had the same problem finding one for my 65 coronet, they are not made. if you do not use the heater, remove the heater hose fittings from the block, weld them closed, put them back on and slip the hoses back on. thats what i did.

This is not a hot rod. It is an Imperial luxo cruiser. It will have a working heater.
I planed on running up to 14,000 feet in a couple weeks. A heater would be nice.

Couldn't you just go with a single core and adapt it to work? It looks like you could get away with half the core if necessary.

The evaporator is set up the same way. This is a reheat system. Air blows across the evaporator then hits the heater core. That dehumidifies the air. Modern cars do this too, especially on defrost.

I would get half warm air and half cooled air. If I were to choke it down to a single core I would lose half my air flow.

Still, the problem lies in finding a 1-1/2" thick heater core that will fit in the box.

I'd suggest burning down the phone lines bugging every NOS guy you can think of. They would probably be happy it's going to a good home and off their shelf (unless you call a couple 'special' guys)...

OOPS!

How about 14,000 feet?

The idea was a run through Colorado. It's currently on hold pending the outcome of this issue.

F body cores are similar sized but a little thicker, maybe just under 2".

Here's one from Classic heaters...

http://www.classicheaters.com/

Scroll down to the catalog link & it's down the page there. There's 2 listed but ones out of stock. 249.00.

Classic auto air doesn't show them on the site anymore but this is essentially what they had.

I'm not sure if the 70 was the same but I'd sure appreciate you looking at it.

For your planning purposes, Pikes Peak and Mt Evans will not be open til Memorial Day. Those are the only two places you can drive that high. Also, Trail Ridge Road (11,000 feet)may not be open until even later as the federal budget woes will not allow overtime to plow it open as quickly as in past years.

Interesting but that doesn't look quite right. Mine only has two pipes inside.

Feets do you have a pic of your actual core?Is your box out or still in the car?I cant remember if my factory parts books go to 72 .If they do I might be able to get a factory parts no.there was a place I got parts for my 57 that had tons of NOS stuff.they were cheap also.Rocky

Re: Where to find a heater core? - 03/08/13 05:51 PM

I don't have a pic of mine since it's at the radiator shop.

I think I have a parts manual for 72. I'll have to dig around when I get home.

Re: Where to find a heater core? - 03/08/13 05:58 PM

I have manuals from the 50s to the 70s.Biggest problem is they are mixed together.I probally have 10000 to 20000 pages.Never really used any of them past the mid 60s.Rocky

Re: Where to find a heater core? - 03/09/13 05:56 AM

I found it in my manual. It's part number 3420787. Well, that's what it used to be. There's not telling how many changes have been made. Here's a catalog pic.

I appreciate the help. Neither number hits on Google.

Feets,

I checked DealerConnect and 3420787 supersedes from 2936201 and from 2932921. No hits on the locator but on PartsVoice, Brad's NOS is shown as having 2936201. Their website doesn't list it though.

Trying calling them Monday and see what they have.

Good luck,

Mike.

I picked up the heater core from the shop today. I'll take it home and do some measuring. If there is enough room the shop will rebuild it with a 2" core.
