Is that with vehicle hot or cold.
If hot then no - When cold should be able to turn by hand easily, as it heats up it begins to tighten up to create more air flow so will be harder to turn by hand.
Ok, you said you checked the Radiator how did you check it?
If you can run your finger along the fins if they disintegrate or break up then would replace radiator.
