I am not sure if this is the right thread or not, but here goes...

I'd love to hear from someone with the the same problem. The first thing I did when I opened my hood for the first time was put my hand down on the air intake tube running along the inside of the radiator. I didn't look I just saw a good place to perch myself to look at my new motor. The air intake tube, unbeknown to me is bracketed to the plastic radiator. The radiator cracked about an inch and a half around the bracket. I applied JB Weld and it worked great for a week until I forgot and put my hand right back in the same place and cracked it again. I put more JB Weld on it and I am sure it will hold fine until... I put my hand there again. What do I do.? Brace up the whole Radiator/Intake bracket, paint the area bright red, or glue a few sharp objects to the site?

 

I did the same exact thing

 

Not really fixable. Just replace it. The problem is expansion and contraction will just work the pb loose eventually. I know PB is pretty good at a lot of stuff, but radiators is not one of them.

Radiators, automotive radiators, condenser, oem radiators, truck radiators

I replaced mine in the middle of winter, in a parking lot. It's not that hard, and not that expensive. I would suggest looking to see if you need new clamps first. The lower one tends to be rusted.

 

That price is way high. I did the same thing on my 90 Civic LX & I bought a brand new radiator for $90 +tax out the door. Rockauto.com has them for around that price shipped.
If the plastic tank cracked it is way ready to be replaced. These plastic tanks get brittle after years of use. My OEM lasted 21 years. That is a long time for these radiators to last.

 

I gave the car away to a friend, but the last time I fixed it it held just fine. What I did was use fiberglass resin and glass fabric (plastic rad. repair kit $10 at O'Reilly). The part that made it work is adding reinforcement. I cut a couple 6" pieces of coat hangar and fashioned them to lie along the contours of the area. Put down resin, laid down the wire and more resin on top. Worked well. I did use my dremel to remove most of the old JB
