core leaking I am having the same issue and it is my core. Good news easy to remove and replace. Of course since it is out I now what to restore the heater before reinstalling it. So an hour job will take days but that is why I look the truck. Our sponsor sells a core but only for the fresh air version of the heater. Good luck.
Re:Control Valve Charles, I remember you were having an issue over which hose the control valve should be connected to. Did you ever get this sorted out?
No, have not had the time to work on that, I was going to add another valve seeing I have it and turning it on in the winter. I still have the shinny one left.But no time to deal with it now, winter should be here by the time I get to it. Been working on getting the 9N ready to sell.
Pretty tough to find a place that sells heather cores. Anyone have any suggestions as to where to buy a core , closest thing I have found is an heater with the core on ebay.
Try this on page 37 http://d1.scribdassets.com/ScribdVi...key-17s7ityn21ee0nwga701&page=1&viewMode=list , Also contact Joe at DZT and see if he has anything available . Good Luck
Im assuming your talking about the heater-defrost assembly? That looks like the best bet to replace the core
If I remember correctly Joe had some, but the truckshop is the one, I would call them to make sure. Also our sponser has this; http://www.classicparts.com/1947-52-Heater-Core-Fresh-Air/productinfo/68-221/ for 169$,,, I usually check our sponser first but this time though you had exhausted all avenues, However give them a call and see what they say about the part being there.
