Need everyones opinion on why the radiator is smoking.

If you can take the cap off the radiator when it's up to temp it isn't hot.
If you can stick your finger in the coolant (at all without getting burned) it isn't getting hot.
And this better be steam you are seeing and not actually smoke, because there is no way in hell it's getting hot enough to smoke and still be running with the cap off or your finger in the coolant.

Rinse that coolant out of the fins and blow them out, because coolant in the fins turns to a sticky coating that will catch all kinds of dirt and dust and make the radiator not cool as well as it could.
