Removing Broken Brass Hose Fitting Threads from Radiator

[Ol'Blue]

Brand new radiator and fitting broke off leaving threads in transmission cooler.

Tried using an easy out but I think it’s just making it worse.

Any ideas on how to get this out?

Was the fitting pre installed ? Broken in box. Possible contact supplier for defect ,, ?? I’d see if they will do something for you before getting to deep , possible a straight flute extractor may have better results , the tapered nipple extractors seem to just continue to ream the fitting , plus shavings drop in side cooler ? Not a lot of help but,

This ^. I won't even allow the spiral extractors in my shop, the stubby ones for extracting stripped out socket head bolts excepted.

This fitting I as trying to install. Must have been poor quality as it didn’t take much to snap it.

It looks like the easy out or extractor will bottom out and damage the cooler so I’m taking it to radiator shop tomorrow and see if they have any tricks.

Is it just the very inner part or would the outside thread looking part come off? If so, it looks like enough to get vice grips on but maybe some heat first would help.

I'd also guess that second part is threaded in that the part is screwed into...that just looks like a jam nut.

So,. that is most likely a much larger fitting and the adapter with a jam nut screwed into it...or is that welded and I just don't see it?

Trying to figure that out as well. Looks like the fitting screwed into a bronze reducer? I can’t claim to have ever done it with bronze but wonder if braze welding a slightly smaller bolt into the fitting could be a last ditch step. I have had it work well over the years welding round steel items like fittings or bearing races. You let it cool well after welding and the molten metal shrinks enough to loosen it up. Braze welding isn’t as hot so I don’t know about the shrink with it. Might be tricky on a fitting that size as well. A small welding tip and brazing rod would give better heat control too.

Now that you mention that, a buddy’s dad used to work for Ford and when I had to get a broken bolt one day, it came up that he would never use any sort of extractor but would always weld something to it and turn it out.

The typical way that the coolers are fitted to an aluminum or a plastic tank is not very different from a bulkhead fitting. Only these "bulkhead fittings" are attached directly to the cooler inside the tank. I think that the external large nut that you are seeing is the "bulkhead fitting's" nut.

I removed the nuts from my old radiator to see how/if I could replace the threaded collar but it’s part of the internal cooler. I think the only way to get it out is to cut the radiator open. It’s so jammed in there and not enough to weld to, I think this is what I’m going to have the radiator shop do.

You could try filing flats on either side of the fitting sticking up out of the radiator and then grab it with a wrench, pipe wrench or vice grips.

I would grind the end off of the easy out that is sticking through too far and then use easy out along with vice grips on the out side of it and try turning both at the same time.

 

[Ol'Blue]

Thanks for all the advise gents. The fitting broke off below the surface of the sleeve and there was no way I could grab it and the material was pretty soft and getting damaged. I ended up taking it to my radiator shop and they will have to replace the transmission cooler altogether.

 

[ntsqd]

Being brass it wouldn't be too hard to simply drill it out, and then chase the threads.

 

[Ol'Blue]

Took it to Mattson’s custom radiators and they ended up having to replace the cooler section. Not using brass fittings again and going with aluminum.

That bites. I’ve seen some crappy fittings that do that so ya just gotta be careful what you buy on Amazon or where you put it. I had that happen on one but fortunately got it out.

Glad you can move on!!!
