(Swapping a core support and matching radiator into a recipient vehicle)
Line 25: Line 25:
 
In doing this swap, you will have to re-install the recipient vehicle's hood latch onto the donor core support in the proper location. Make up a fixture beforehand from scrap metal that bolts to the fender bolts or some other location that will be the same after the core support swap, and will show the proper location for the latch.

===Recommended donor vehicles: '76 Cadillac Fleetwood or Eldorado===

*'76 Cadillac Fleetwood or Eldorado. For example: [http://www.radiatorexpress.com/product.asp?part=1976+CADILLAC+FLEETWOOD++%2D+8%2E2+liter+V8+RADIATOR+Name+Brand+Replacement&part_id=1357&aaia_id=1026582 1976 Cadillac Fleetwood 8.2 liter V8 radiator].

*Mid-70's Chevrolet truck with a 454. For example: [http://www.radiatorexpress.com/product.asp?part=1975+CHEVROLET+C20+PICKUP++%2D+7%2E4+liter+V8+RADIATOR+Name+Brand+4%2DRow+Capacity+Upgrade+%2828%22x19%22%29&part_id=39583&aaia_id=1031971 1975 Chevrolet C20 Pickup - 7.4 liter V8 radiator, 4-row capacity upgrade] (and, same radiator in aluminum: [http://www.radiatorexpress.com/product.asp?part=1975+CHEVROLET+C20+PICKUP++%2D+7%2E4+liter+V8+RADIATOR+All+Aluminum+4%2DRow+Capacity+%2828%22X19%22%29&part_id=218171&aaia_id=1031971 here].

==Cadillac radiator swap==
 
Any of the Fleetwoods or Eldorados from '70 to '76 with a 472 or 500 will work, but the '76's used the 500 inch motor for sure.

Line 36: Line 40:
 
With that accomplished, simply attach the middle piece of the Cadillac support to the stubs of the recipient vehicle support. Use whatever pieces of sheet metal or whatever that you have to in order to make the connection. The Cadillac support may end up sitting forward of the stubs or a little behind them or it might fall exactly into place and you'll have very little welding to do to stitch the Cad support and the stubs together. Whatever. Just use your head and figure out how to connect the sheet metal, then MIG it in place.

Now, you will have a radiator that will cool anything and you still have the stock attachment of the  stubs to the recipient vehicle so you can use simple hand tools to disassemble the whole mess later if you have to. It'll all come out as one piece because it is one piece.

RPM responded to my post with this post:
+
"I have have good luck doing what Techinspector1 suggested but I used a radiator and support from a mid 70s Chevy truck with a 454. It is a big 4 core radiator. If it will cool a 454 in a towing application it will cool most anything."

Here's the radiator RPM is referring to in copper/brass:
