I have a 70 Dart Swinger with a slant 6. While servicing the cooling system, I came across this fitting. Anyone know how I can remove/replace it? It looks like it is about to fall apart!

Thanks!
 
There's a good article in the "how to" forum on this site
 
Thanks fnabody. The article references the manifold. My fitting is on the head. Do you know if this is threaded?
 
When i got my car it was about the same condition and i didnt want to break it off. I got a piece of hose that fit inside,put som black tape on the end stuck it in, grabbed some jb weld and used a small washer for the flange. It was a temp solution until i dropped a new motor in the car but my twins,came motor got put on the back burner and ive been driving it for about two years like that.
 
The article talks about it being in the manifold because that's where it is on a V8 engine. On the \6 the fitting screws into the head but the suggestions in the article are still correct.

In the end you might wind up breaking it off and having to drill it out then retap the hole at the next bigger thread size. Then install a (brass!) new fitting with the new thread size and the correct hose barb size.
 
The "how to' article I looked at uses a hacksaw in a larger I.D. fitting. I don't think you'll get a standard hacksaw blade in this one. What I would try... First, remove the accessory bracket for greater access. BP blaster or similar solvent. Place a piece of material inside the fitting, round, hex, even square can work. This allows a little crushing but prevents total collapse. Place the smallest pipe wrench or round jaw vise grip flat square close as possible. When we're lucky the fitting will back out. When we aren't so lucky... We cut it away flush to the casting then drill and re tap as slantsixdan stated. Good luck
 
Those ****'s can be next to impossible to remove. ......
Sorry to be so honest. .

Try heating it with a propane torch before removing it... You may have better luck that way...
 
pipe extractors are like EZ-outs for stubs. Drill and tap in then cross you fingers and turn them out after soaking in PB on the outside only. If this just strips inside due to rust or corrosion, tap the sides in with a drift and just keep going until you finally break it into pieces and pick out, then chase the threads. Somewhere it was mentioned that if you heat both with a torch and then hit the stub with some Freeze, itll break the bond, or hit the hot threads with wax, its supposed to draw in like solder and eaze removal.

That is a heater hose nipple. A pipe wrench will grab it, but the sides usually fall in if the walls have corroded too thin. Use penetrant and heat. Keep applying torque back and forth until you hopefully see it move, then keep flushing in penetrant and going back and forth to flush out the rust, then it should unscrew. I have unscrewed them even when the sides collapsed. Wrap Teflon tape on the threads of the new nipple so it comes out easy in 30 yrs.
