JB Weld - is it strong enough?

need to hold one of my metal elbow tubes from my water pump inisde the pump. this is the tube that the rubber hose connects too. not going into a story- but the elbow is lose and leaks. will jbweld hold this metal elbow in place during operation on boost from my s-trim? if not what other type of material stuff can i use.. thanks

is it worth having the jb weld let loose when you are spinning 7,000 rpms and possibly risk damage to your supercharged engine?? It might work, but i deffinately wouldnt rely on it for too long. Make sure you give it plent of time to set and you allow it to set at 50*+. Good luck

I had the same problem over 3 years ago. I used JB Weld on it and it's still working... :)

From time to time i work on construction equiptment, and I've used that many times to seal cracks and stuff like that and as long as you give it enough time to set and you in failry warm temps you'll be all set

I used J.B. Weld on one of the fittings on my water pump over a year ago and I haven't had any problems since. I piled it on really good...I don't think I could remove it even if I wanted to! :thumb:

I used the stuff on a radiator,it held for a couple of years then the rad went out in a differant place. It might be better to retap the hole to a bigger size though.

a chain popped on a motorcycle cracking the engine case...JB weld sealed that up for years...

this is starting to sound like a commercial


Thanks JB WELD!! :D

Sure itll hold it, use the 24 hour kind and not the 10 minute kind for added protection

Make sure the area is very clean and dry. Thats the major cause of JB weld failures, especially with cooling systems. I've JBed stuff on my car 4 years ago... Heathers LT-1 is literally held together by JB ! I even use it for body work !

It's good stuff for sure :)

hey guys thans for all the good info :) yeah the motor is torn apart for some head work being done. so the water pump is bone dry and not going to be getting everything back together till spring. so i will just slap the jb weld on and let it sit. thanks :)

I hate that stuff. :(

I'd feel safer trying to patch a hole with a kid safe stick of glue.

If you have it that far down why not fix it the right way and not have to worry about it? Any shop should be able to retap and install the right piece for just a few bucks,it's not major work,only ten minutes tops.

Why does everyone say to retap it ? It's not tapped in the first place.
These are press fits, and trying to find the proper size for a threaded hole is almost impossible due to the size.
The best way possible would be to have someone tig weld it, but it's kind of overkill.

So,you are saying,"you want to put a press in fitting in a threaded hole?" Okay by all means go with the Epoxy(JB Weld)that is about the only way to do it,other than weld and then you still run the risk of a leak,due to welding over threads. Sorry for the misunderstanding.

No, he's saying the hole is not threaded in the first place. The fittings are pressed in from the factory. If they were threaded, the fix would be simpler, and wouldn't we all have some nice Earl's fittings in there...

Okay I've got the picture now,I haven't seen this yet(water pump) so was asumeing it was the heater hose barbs. What size hole are they? If you have or can take the pump off you could tap (not retap) the hole ,and maybe go with something from Earl's. Sounds like GM got cheap and screwed-up again,or could they be sweat sodered and it just broke loose? Either way the JB should hold fine. Sorry for the confussion,but that's how we learn. :)
