I don't see why you don't just take it out and send it to a radiator shop. That's what they do. It's not expensive, and they'll repair any holes that this process can uncover, and then pressure test for leaks.
Some things are best left to the professionals, and this is one of them.

Sorry for not so exact answer but..
Citric acid can probably eat some of the aluminum if solution is of
very high concentration. That being said, I do not think that You
would be able to do damage to Your radiator very easily with citric
acid alone. It can etch the aluminum. Etced aluminum will look dark.
Just etching does not damage the aluminum (well, it does but not
significantly), but at that point You have already solution strong
enough to change the composition of non-corroded aluminum. Different
acids have different properties with metals, but generally oxidized
metals You want to remove here are more actively reacting with acids
than the healthy metal itself.
The radiator should probably be cleaned with some cleaning detergent
in order to allow citric acid to contact the inner surfaces of the
radiator. Oil for example on the surface will prevent citric acid from
doing the magic. Some commercial products meant for this probably have
cleaning detergent already in addition to acid itself. I like my acid
and soap separately.
And do stay on mild acids when working with aluminum. With stronger
acids You wont be able to find Your radiator anymore.
