If it thawed out the problem is not likely to be the radiator, when those freeze they break and leak. Rent a pressure tester and see if the cooling system will hold pressure. If it holds pressure the issue could be a failed thermostat that is not opening.
If it fails to hold pressure it is something like a head gasket.
