HELP!!! My heatercore is leaking!

[Gautam]

But its leaking through the top fins! Is there anything that I can do, or is time for a new rad? I found out that its only one fin. Could I just fill it up with rubber cement, or is this going to restrict something?

Yup JB Weld!

Never done it with a pc rad, but I sealed a car radiator with epoxy once :D

Lost quite a bit of surface area but the car never overheated.

There is not as much excess cooling surface in a pc rad though: if you lose too much there may be a severe impact on perfromance.

I would try it, since you have nothing to lose, but be prepared to get a new one.

And You have nothing to loose, i agree jbweld it, use the normal long drying stuff, the fact that it runs a little might actually help you in this case

Good Luck!

Thanks, everyone. I'm currently waiting for it to dry. Its only one fin that's leaking, so sealing this only wouldn't hurt significantly, would it? Hope it works out; even if it doesn't, its no biggie.
