Radiator leaking for top area

Not 100% sure, but from what I can tell my radiator is leaking from the bottom of the fill neck. Is there anything I can put around the neck where it meets the radiator that will hold and keep it from leaking?

That looks like a brass radiator, which means it can be soldered. You'll need to clean off all the paint in the area. Use an acid flux and plenty of heat.

Would JB Weld hold/seal it?

Pull the radiator and take it to a shop, or..

X2 ^ it's not that difficult & will save you a lot of money compared to taking it to a shop

Haven't done any soldering before but will give that a try. Would it be a problem leaving radiator in Truck and not draining the antifreeze out or would I need to drain? Thanks.

Re: Radiator leaking for top area

Its best if you leave the coolant in as lomg as the level is lower then the area you are going to solder. Read up on soldering real good. The area has to be clean. Get a small tube of flux to make it flow good. Most solder has flux in it but its not enough for something like that.
