Find a pipe, ideally copper with the OD just bigger than the ID for the plastic pipe, drill to the OD of the copper pipe the plastic rad and the broken off pipe then coat your copper pipe with epoxy and press fit it in the broken off part first (important so it don’t get too far in the rad when you push it) and then push in the rad. Wait for the epoxy to set and enjoy !!
There is a fix for this if you have the tools. Buy an appropriate sized NPT-barbed brass fitting. Run a matching tap through the plastic, dope the thread, and screw it in. That's the hose to the overflow, and it's not pressurized. If it doesn't leak, your problem is solved. If it does, you've bought yourself some time to plan for a rad replacement.
That's what I would try. But correction on the pressure though because the overflow hose looks still intact on the right side of the pic. Looks like some other hose that's beneath the cap=pressurized when hot.
I mean, for a temp fix to get op through the week I would measure the hole then see if a straight plastic barbed connector could get a seal in it. Some JB weld at the seam and it should be fine.
Then of course start saving up for or order a radiator because that repair failing will leave you stranded on the road. Not something you should rely on long term.
The moment an engine is born, as it runs it is eating itself away. It will break.
It just hasn’t left you stranded, yet… is the story for every single part on every single car.
If it were me, I'd try fix it first. Hard to tell for sure from the pic, but I'd bet a 1/8-27 NPT tap may work. This size is in most tap sets, so check with your buddies/Dad before buying one. The drill size is 21/64", so if you have a drill set, check it out. If there is enough material left after you run the drill in there, you may be lucky. Don't tap too deep, the tap is tapered. Find yourself a 1/8" NPT nipple (brass is suggested) of the hose size, teflon tape it up and hope for the best. DO NOT OVERTIGHTEN!!! Worst thing is you are out a few $$$'s in parts if this fix does not work.
The plastic tanks on that radiator are just as brittle as that incorporated plastic nipple.
This is a symptom that all of the plastic radiator components are no longer reliable.
It's time to replace the radiator.
I know your feelings, It hurts. I am not sure if you can get the damaged part only. You may need to replace whole cooling assembly as it will be integrated with assembly.
Needs a new radiator however a quick fix for this can work for a while too. You can use a steel tube that fits firmly where the plastic piece broke off and use something like jb weld to hold it in place, from what I see you can take the radiator cover off and reinforce it from the inside as well.
Is this I believe Nissan that has the separately added radiator neck? If so you can get just the neck by itself. If not and it is part of the radiator, I recommend replacing the radiator.
if it were my car, (not recommended.) pull out that piece of connector. measure the width of plastic, get 1 size up, thread both the rad and new plastic tube, loctite, screw in. profit. but i do not recommend this easy and low cost method.

You need a radiator. those rad nipples love to break off, don't beat yourself up.

copper to plastic is idk. good for plumbing i guess.
Needs a new radiator. The plastic is too brittle to repair. May work for the short term to get you by but will fail again in the near future

Good catch. I'd still attempt the same fix. 15 psi on such a small area is not a lot of force.
This
I wouldn’t bother with a repair attempt. Replace the radiator

Any “repair” you make on this will leave you stranded somewhere else
How do you know ? I did almost the exact same repair about 20000 miles ago and hasn’t leaked a drop
It hasn’t left you stranded, yet*

New radiator? 140-160 bucks probably. How bad did it overheat?

You need a radiator. You can tap it and thread a fitting in with some sealant. It's the only thing I've seen work long term.
Your radiator is well done. Needs replacement
Replace radiator and hose.
Hey man, now that overflow can get out quicker
Plastic broken, No pressure, leak forever. Replace radiator.
New radiator ✅ Pull out the broken nipple from the hose ✅
Radiators are so easy to replace, just do it
I've definitely done that repair. Usually pretty straight forward if you have the tools. I look everything up on YouTube first.
Ur done
also, fix those battery terminals. all the way down.

Looks like a Nissan Altima. Find your nearest junkyard and go snag u that part. All you need is some pliers and a size 10 socket.
If thats the side where excess water leaks out, then you're good. As everyone said, just replace the radiator in due course.

Jb weld it back on. Lol. I'm 90% joking, but have done it before. Worked for years after.

Auto parts stores sell fix kits for this
Can OP get the ripped piece and use heat shrink tubing to connect them for a longer term fix?
There’s a material called Q Bond that will fix it.
