2.5L temp sensor broke. Any ideas?

Guys,

I tried to change the temperature sensor on my 1984 2.5L. I removed the old one fine and cleaned the threads with a small brush. I started the new one in with a ratchet (no big force or anything), and all of a sudden it just broke, near the top of the threaded part. Now, I am left with a (sort of) plug in the engine, a dead temp gauge and a huge problem.

How to remove the part left in the engine?

I was wondering if you have any ideas on how to remove it, so that I can put a new sensor in.

Any help would be greatly appreciated.

2.5 lt temp sending unit broke but I've managed to remove it

Well, I've managed to remove it, so here is how I did it, just in case someone has the same problem in the future.

I took a torx bit which just fitted in the part that was left in the engine's head and an extension. I then hammered that bit inside the piece. Using a ratchet, very carefully, I was able to unscrew the stuck part.

Now, I just have to wait for the local DC to get me a spare part.
