Take a close look where the fins attach to the tubes. If the fins are
corroded and falling out, the rad isn't good. The fins are what transfer heat
to
the air by increasing surface area. If you had a rad with tubes only it would
not be very good at transfering heat.
Past that, a pressure test is needed. Make sure you tell the rad shop person
your system runs at X pressure. If you have a car that runs at low pressure
they might test the rad at modern pressure 20 PSI only to have it pop.
