Blocked and no overheating?

Sounds to me like your radiator is doing what it was designed to do. Radiate.

That is what it is supposed to do. If the engine is not overheating - it is working.
Hot comes in from the engine on top Driver side. Exits to engine on lower passenger side.

The OP says one side is extremely hot and the other side is extremely cold. That's one hell of a radiator if it can keep one side hot and the other side cold. Degrees of difference side to side yes but not as the OP describes "extreme".

It does sound to me like the radiator may be clogged but why the car does not overheat I cannot understand.

What is the overall coolant temp in the DIC? Could the transmission cooler be causing this I don't remember which side its in. Is the transmission temp high in the DIC?

I'd say it's working as designed but the conditions are exaggerated a little. It would be impossible to be extremely hot on one side and extremely cold on the other unless the car just started and the thermo hasn't opened yet. If the case was as described it would be overheating and puking coolant everywhere. Or the whole thing is frozen solid. But that would still overheat and puke fluid.
