My roommate replaced his Honda radiator the other day and gave me his old one. There wasn't much on it besides some plastic and a single small brass pipe. So i decided to cut it up and melt it down using my small foundry i made awhile back. Started out a bit over 3lbs 12 ounces and ended up with a bit over 3lbs 1 ounce of pure aluminum ingots. There was about 4 ounces of dross left over and i guess the rest of the missing weight was just from grime and some flashing of the aluminum.
Edit: Unfortunately this forum won't let me upload pictures from links yet and the "manage attachments" option only allows 200 bytes max to be uploaded which is extremely small. Otherwise i would put up some pictures of the radiator and ingots.
