Hot Water Radiator Problem

jimc101

I have old hot water radiators that all work perfectly except for one.  I have bled this unit but do not get heat.  The line feeding into the radiator is warm but this is never felt in the radiator.  Might I have a small blockage in the radiator?  If I can close the valve,  can I  snake the unit?

Close the valve...

Then bleed.... allowing the make up water to come through the return line.....the return line may be air locked...
