Well, it depends on which oxygen sensor you are looking for. There are about 4 on the Gen 3 Vulcans, and maybe more on a Gen 4. The instructions are the same regardless of engine type (Vulcan or Duratec) or sensor (Bank 1 pre-cat or Bank 2 after cat) But one may be easier than the other.
1. REMOVE THE NEGATIVE LEAD ON YOUR BATTERY FOR SAFETY.
2. Locate the oxygen sensor to replace, this is quite simple actually, look for a little metal probe popping out of the exhaust tubing.
3. Disconnect the sensor "Pigtail" from the vehicle's wiring harness.
4. Use a "Crows Foot" Wrench or a special "Oxygen sensor removal Socket" to remove the O2 sensor from the Exhaust tubing bung.
5. (If your new sensor has this grey goop(anti-seize compound) on the threads skip this step)Take the new sensor (which can be acquired from your local auto parts store as well as the tools required and possibly detailed instructions on how to do it for your specific make/model) And cover the threads (ONLY THE PART THAT THREADS TO THE BUNG) (Be careful to ONLY get it on the threads or you will damage the sensor) in anti-seize compound. (available at your local autoparts store)
6. Thread the new sensor into the piping bung by hand to make sure you do not "Cross-thread" or damage the threads.
7. Tighten it down with the special socket or crows foot wrench wrist tight. DO NOT OVERTIGHTEN.
8. Connect the new O2 Sensor pigtail to the vehicle's Wiring harness
9. Reconnect the negative lead to the battery.
10. Turn on the vehicle and check for any exhaust leaks.
Happy Motoring!
There's one in each exhaust manifold. You will need an oxygen sensor socket to get them out.
One tip for removal, if you are replacing the sensor with a new one you can snip the wires off the old one and use a 7/8" box wrench to remove it, you get a better grip on the sensor with the box wrench than you do with the crows foot or even the special socket. If you can't get the 7/8" box wrench down on to the sensor because of obstructions you can also use a standard deep 7/8" socket as long as you cut the wires off first.
