Crimping a radiator side tank

Okay you guys thank you. You gave me a couple of ideas. The first one was to lighty crimp where the leak was and just above it.
And number two was to strap it from one side to the other so I used plumbers tape. Along with a little duct tape for insulation to keep the plumbers tape from rubbing against plastic housing.

Thanks again for your assistance I knew I could find an answer if I just asked you guys.
