eander315:
It is an after-market Honda Civic radiator (92-00), supposedly all copper. The top and bottom tanks seem to be molded plastic. The plastic doesn't bend, and at first I thought it was metal. The fins and the rest of it are probably copper though. It's hard to tell because it is painted black. Even looking inside it you can't really tell. The fins look copperish. This guy on Ebay sells them really cheap ($50 US shipped.) It has a core size of 13.75" x 14" and 1.25" thick. It is a double row (has dual fins one in front of the other) and is single pass (no U turns).

jman1310:
The plastic collar on the radiators (the neck of the radiator inlet and outlet) are .865" or 22mm. The metal barbs I wanted to use are 1/2" but have 3/4" (19mm) threaded ends.
I hadn't thought about it expanding and contracting at different rates! I had my heart set on that shiney brass look. But I think now I'll try to find some nice plastic barbs instead. Probably easier for the glue to bond to anyway.

bigben2k (or anyone):
Is there any real difference in Silicone sealant and Plumbers Goop? Is the Plumbers Goop brand really better?
