some new problem always pops up as soon as i resolve one. Now i've got a radiator leak. there appears to be a tiny crack right underneath the serial number. I wiped it clean, started the car, and watched the fluid leak out. see picture below. Is this something that can easily be repaired?

don't take the chance. with a ghetto fix. Just replace it. would you rather buy a radiator or a new engine?

I would *try* out some epoxy or JB Weld.
Let the car cool off, make sure the spot is PERFECTLY clean (use brake cleaner and remove any / all residue), and try it out.
My *guess* is, that it will work. I don't know if it will carry you through the summer, but it may hold up just fine for now.
I would at least try that, and see what happens.
If it doesn't work, you'll lose maybe $5 for the JB Weld, and have to replace the radiator.

I would scuff the area up and try some of the 3M plastic weld that we use to make ghetto IM's. If it holds an intake together, it should hold that. It is rated at 4000 psi tensile strength or some insane amount. Maybe use some alcohol to clean it, as ethylene glycol is an alcohol byproduct; it might clean any antifreeze out of there to help the bond. $4 or $5 beats buying another radiator.
That's all I can think of ATM.
Edit:Too slow!

Plan on keeping the car?
Bite the bullet and get a new rad.
I have no problems with my upper/lower rad hoses or rad at the present time; however, I have plans to replace all those parts in the next few months... just need to pickup the lower hose and rad now.

I just replaced mine, cost me about $150.
Just replace it, no need putting stuff and clogging it.

bad idea. don't buy online unless its from rockauto or modern.....
go down to your local autozone/ pep boys / kragen and buy it from them. if anything happens the warranty will cover it. and you don't have to reship if you buy it online.

Putting some epoxy on the outside will not harm the inside in any way.
But since you plan on selling the car, a new radiator would be a good selling point. Otherwise, I would just use
this and cut a piece of thin black plastic from something, to put over it so it bonds/looks better. Maybe hold it tight with some shipping tape for 15 minutes till it sets good. Walmart carries it for under $4 in the fastener section.
My bad: was thinking 3m for some reason.

No way! Is this a common problem or something? I just replaced mine yesterday because it was cracked in the exact same place. You're going to have to replace it. Whatever it's made out of won't let anything stick to it. Plus with the expansion and contraction, whatever you put on will just pop right off. I ordered mine from go-part.com, $96 for a KOYO radiator didn't seem like too bad of a price to me. Shipping was like $16 from Cali to PA.

I have a radiator crack in the same exact location.......it seems common (relatively speaking) on these older ones i guess......

alright...so here's the plan. I'm ordering a radiator tonight for around $100. I'm going to slather on a fuckload of JB weld to get me through until i receive the new radiator. what's your guys' take on installing it myself? It'll save me the $40 i would pay to have it installed. ( a guy I somewhat know)

No use taking it to a garage, it's not that hard to replace, especially if you have a CAI. If you don't, it might save you some frustration to take your airbox out.

i replaced CAI w/ stock intake during last monsoon season and never bothered putting it back :-/ thanks for the tip though. Any thing else I should note? Are there any extra precausions I'll need to take in this project?
ibtw, 'm buying a KOYO intake from go-part.com as suggested. Thanks!

Hmm.

Maybe I should put some JB Weld or Epoxy on my radiator in that spot, to reinforce mine now, BEFORE it breaks.....

I woud use the epoxy that I linked in post #12
(this)
I don't know how well JB weld would hold. It is the only stuff that came off my home made IM when the neon got totalled, I mainly had it there for cosmetic reasons, but nonetheless it didn't take the impact, and the Loctite wasn't phased, the intake help up amzingly well for a glued together piece of plastic. The only thing that broke was the JB.

Thank you for the tip.

I will try that out.

try the lock tight. the JB weld takes 15 hours to set, and didnt stop the leak. (it did help it though) i'd probably need to do a 2nd or maybe 3rd coat. cant wait for the new radiator to come in

Crap if you were close (CT) I'd offer to do the install for you. I replaced mine w/ a Koyo a few months back with 0 problems since.

You should get a few bucks for it from a scrap metal yard. Prolly more if the plastic is removed. A radiator shop might give you something for it too. Either way, it is more than you would get by pitching it in the trash.
