Radiator overflow 'nipple'

jfiscus · Feb 5, 2008

I was changing my water pump the other day & when I removed the overflow hose from my radiator the little plastic tube went with it. The tube felt brittle inside the hose as well, kinda like it dry-rotted?

Anyways, my Jeep seemed to be cooling just fine before the waterpump went out, and I'm not wanting to replace my radiator right now, so what solutions can yall come up with to fix my nipple problem?

This is a 93 XJ, stock cooling system.

Could you try to tap out the hole and install a brass barb in it? I know it's plastic and all but I would think there's a chance it would work. Maybe put a little JB weld on the threads?

Same thing happened to me. I screwed in a brass fitting and then siliconed the hell out of it and let it sit over night. I haven't had a problem yet ( knock on wood )

How far did the nipple crack? All the way off?

yes, all the way off to the main "tube" where the radiator cap is located.

I was thinking of installing a tapped tube but was not sure if the clearance was there with the cap being right next to it.

Mighty Putty!
but seriously, i was at Ace hardware and bought some generic epoxy putty and i was somewhat impressed, the stuff does seem to work. the tube was a little under 5 bucks.

I used a little piece of metal tubing. Worked fine and lasted until the radiator itself went bad. Because of limited space, you're best off taking a little piece of brass or copper tubing and threading it directly with a screw thread, rather than getting one with a pipe thread base. A straight thread will work fine. It's not under pressure, so you also don't need a barb at the end as long as the hose fits snugly.

I was thinking about the clearances with the cap as well.

Oh well try it. if not you can rig up something with a tube and epoxy.
