Ford 1720 coolant piece broke in block

[etpm]

Thanks for the replies, I tried the ez out this morning and got a good bite on it but it still didn't want to break free. I put some pretty good pressure on it but think i might break the ez out if i try any harder. Ill let it soak in pb blaster for a few more days and try again, if that doesn't work then i will break out the dremel and see what i can do.

You could also just use a file to file through the wall of the pipe until threads start to show. There is a tool made for removing pipe nipples that most good hardware stores sell. This tool has splines and a splined wheel that has a hole drilled off center. When inserted into a pipe and turned the wheel cams outward and grabs the inside of the pipe. Cutting a groove in the pipe wall and then using some penetrating oil along with the tool could just do the trick. Just let the penetrating oil soak in for a while.

Drill it and tap for a pipe thread.

I thought this too but it's the threads between the fitting and the block that are causing issues. So to properly fix this the fitting needs to be removed from the block.

I've used a similar idea only cutting with a hacksaw blade. Just wrap a rag around the blade to protect you hands and start making a slot in the fitting. Once you have reached the threads quit cutting and use a punch and hammer to slightly collapse the fitting. You might have to cut two slots but once the threads are loosened up the fitting will easily come out.

I like the hacksaw idea. Because the pipe is probably rusted in place, and because rust expands which makes things tight, slightly collapsing with a punch is a good idea. The broken pipe doesn't need to be saved, it just needs removal.

Slow down and try to get some penetrating oil in the threads. It has been a day, and that is not enough time for the darned oil to soak in. Another term for penetrating oil is creeping oil.

I would clean up the area and dry it off. Then i would try squirting penetrating oil on the threads (WD40 is not penetrating oil) and keep it wet for a week or so.

The process is slow, speed is what got you into this situation, patience will get you out. To reiterate: put penetrating oil on the threads and keep it wet for a week or so.

Good advice from @ Sportsman762!

Also, I have noticed in one or more of the attached links to other threads, that this fitting might be/is British (BSPP or BSPT?). Best to not replace it with an American NPT fitting: they have different thread angles.

Once I got mine out on my TC45DA I used this to replace that valve. It threaded right in it also works great and it’s easy to drain my antifreeze.

I was able to get the old piece out of there. Ended up drilling it out and running a 3/4 bsp tap to clean up the threads. Unfortunately I am getting deployed overseas on friday so I didn't have the luxury of time to let the penetrating oil soak and get the tractor going before i leave. @Sportsman762 Just waiting on the replacement part to show up so i can get it back together and going. Thanks
