Ok, soo Anyone know what this core came from? It doesn't look like anything Grumman van like, nor is it VW! Anyone have an idea? Mine started to leak and is currently pulled from the car, but it is getting cold again.

I have taken mine to a rad shop and had them repaired.
I also had to replace one once as it was beyond repair I found some that are a similar shape and size and have had success with them.
I have one in the shop that I think came from a newer VW jetta I will look for it an see if I can find a part #

Mine was leaking when I got my van, so I took it to a local rad shop and had it recored. Any rad shop can do this for you.

Jacobs right however in recent years I have found that you will want to find an old world rad shop where they actually know how to silversolder rather than simply replace factory components. It's a sadly changing world out there.
For information here are some photos of heater core elements that I have planned to use or have used in the past.
The photos are on or in the heat exchange box for reference.

This is a new unit I think from a newer Jetta, made by "Spectra Premium" part # 94730 with a sub # of 399903
This will require serious re-plumbing and would not be my first choice

These two picture are a core from an 87 Chevy Silverado pickup truck, it in my mind is the best fit it will require some re-plumbing.
This is my first choice for the next core failure, it is the same size and the re-plumbing would be minimal.

This one I picked up from Princess Auto in Canada you can probably get it from Harbour freight in the US.
It worked requires some re-plumbing but did not really throw out a sufficient amount of heat.
I ended up pulling at and replacing it with a rebuilt unit.

So that's my experience, my first choice would be as Jacob says find a rad shop that's been around for a while and has the time and patience to help you out.

Good luck

hmm ok, I will look around. I am finding it harder and harder to find really good shops. Maybe I will do the work myself, it isn't that bad if you have the raw materials. I did find a core that will work (I think) I will plumb it in and report with pics here so we all have it :D

Well that was an expensive adventure! I had it repaired, but it cost about $90 for them to seal up one endtank... fingers crossed I am not going to have it leak again. The next step after this is to custom build a different heaterbox.

I paid $175 CDN to have mine recored. I hope I never have to do that again.

I haven't had to deal with this, army core is still in good shape. I've got a friend that replaced his, he used one from a stock vehicle, I can ask what it was so it will be in the archives.

Pop, that would be greatly appreciated. Stuff like this isn't in the service manuals on the site.

I am also going to make sure I do the same thing for the ebrake cable parts since it seams they are not stock components.
