When I pulled the radiator on my 73 there was no drain plug. I'm sure it wasn't original. I pulled the hose off the lower radiator connection and tried to keep the anti-freeze in a tub. As it turned out I had to wash the garage floor. Good luck.

Even if you pull the lower hose, some coolant will still be left over in the radiator. How did you drain that?

There should be. How else do you get the coolant out?
My '69 has a drain/petcock on the bottom passenger side. The radiator is original, and I believe it's a 1/8"NPT thread.
Not positive it's original. Anyone......?

That is why the garage floor got washed.

I can't find mine either. Maybe it's not the original radiator.

However, I think the BBs had copper radiators, so this info might not be valid for rajsid.

Also my aluminum radiator looks like original, it has stamped number 3155316 on the top left side and just under the number is welded a small plate with number 700 (I am not 100% sure of the numbers, it is a bit hard to see)

My 69 350, a/c, has a copper radiator without expansion tank. That may be the key. The radiators were different for a/c optioned cars. I fell into that when I was shopping for the correct replacement support.

Jeb, you could be right, my car is a no a/c, with expansion tank and L46 engine.
