This happens constantly. More so when I’m in traffic or have it idling for a few minutes and the oil temp reaches 210.

Once I turn it off or if I leave it idling for more than a few minutes coolant starts leaking out of the radiator. Do I need to replace the radiator or is there another fix or is this not the radiator?

I attached videos

 

Edited: I used another player and saw the leak. It looks bad.

Once the engine heats up, the coolant is under pressure which can open a small crack and leak. Once you turn it off, the coolant no longer circulates so it get super hot in the block and can force the crack open. Remove the electric fan and see if you can spot the green residue.

Look under the return hose and see if it's running down the tank.

 

Check the line from the top by the radiator cap to the overflow bottle for cracks. If that's not it, then inspect further and see if it's coming from the ends of the radiator or maybe where the large hoses attach.
