Sprung a radiator leak

So it's close to 60* today in ohio, so i fired up the camaro to take a couple of laps around pictown. Took it back to polish up the wheels and all of a sudden I hear water streaming underneath my car.

Water was streaming from the plastic framing on the radiator directly under the cap. It ran a little hotter than normal, but I attributed this to city driving, but temp usually isn't that high. Wasn't even close to overheating, but was hotter than normal. Is this fixable or do I have to put a new one in?

Thanks in advance gurus.

i would replace the rad, if it were in the metal you might try some stop leak, but i would never use that stuff in mine

Yeah I'd say new radiator stop leak seems to gunk everything up in your rad/engine.

If they are still available, you can replace the plastic tank. I did mine about 4 years ago. It is a pain in the rear to straighten what seems like 50 aluminum tabs out and them tighten them back up - but knock on wood I have not had a problem yet.

Guess I don't really know how my radiater is built. The plastic on the sides are covering what exactly and can I just solder the hole shut without pulling it or replacing it. Not part of the budget for the moment, so I would like a permanent fix.

Any good pix of a radiator pulled from a car?

Thanks.

The side tanks are plastic. Patching one might be a little iffy. The core is aluminum.

A new radiator is less than $200.

I've fixed a radiator that had the plastic sides crack with JB weld before, lasted for at least 14 months including 10+ road trips.
