1. Buy the proper tools at your local auto store.
2. Disconnect the negative battery terminal in order to avoid any possible electric shocks.
3. Locate you oxygen sensor and use the special tool to remove it. It may be difficult to remove the sensor, so it does require some elbow-grease (strength). If the sensor is "stuck" turn on the engine long enough to warm the surrounding area of the oxygen sensor in order for the metal to expand and loosen the threads.
3. Re-insert the new oxygen sensor and apply anti-seizing grease on the threads. Tighten the sensor all the way, but dot use excessive force to tighten it.
4. Reconnect the wires to their original socket.
5. Connect the negative battery terminal.
Oxygen can very pricy. To get the cheapest price I would recommend Amazon.com because they can offer you the lowest price for an oxygen sensor. I received both of my oxygen sensors for 100 US dollars. If I would have gone to my local auto store I would have spent around 170 US dollars. Good luck!
