Mercedes: 1985 mercedez 190e 2.3, sencor, mercedez

Question
I went to replace my 02 sencor and it snapped off wat can I do to fix

Answer
If the wrench shoulder broke away the you will need to drill our the center to the remaining unit and use a back out to try and remove the threaded area. It is important to select the correct drill size in relation to the back-out. You man need to heat the pipe with a torch to help it release. Obviously you would need to go slow and make sure that you do not cause a fire if heating is required. I would spray and let soak the threads with blaster to help lubricate the threads.
Good Luck
