I have to replace the sensors on the tail-pipe, but I am concerned
about doing that because of the heat situation. I know there is a lot
of heat there and I am a little bit worried that these items maybe
welded to the pipe and removing them may cause a leak of some
sort.basically what I am asking is: what do I need to consider when
removing these sensors. Is there any special precaution I need to
take. Heat expands and cold contracts. Is it better to remove when
warm or cold? Any advice would be helpful

Most of the time with the proper tool, factory installed oxygen
sensors break loose with little difficulty, since the factory
uses the proper anti-seize compound on them. Sometimes they can
be a bit stiff to thread out because stuff has built up on the
threads, but they generally come out. It's when some backyard
bozo replaced them already and cheaped-out by not using the
proper anti-seize, that you may run across difficulty.
Some replacement oxygen sensors come with a small package of
anti-seize compound in the box. Some dishonest auto parts store
clerks steal them. Check before you leave the store.
HEY! I resemble that remark!!!
Actually, why steal a little tiny packet, when they usually ship a dozen
spares in the box, and a whole tube of the stuff costs a buck with the
But, I suppose people will take anything...
