Crimping a radiator side tank

Okay it's not an a body it a 98 Durango radiator.


Here's a question can you recrimp the side tanks in order to tighten up the seal on the radiator?

This thing leaks at the bottom 3 in of that seal on the tank and I can push against the radiator hose and it'll gush out and I can pull it back toward me and it'll stop leaking.

From the tip of those pliers to the outlet is where it will seep while in the vehicle I take it out of the vehicle it doesn't leak unless I push against it.
