After finding the correct tool for the application you then jack up the car in most cases. Find The o2 sensor in the exhaust system most likely at the front of the car behind the front wheels about 2 feet in. Loosen the o2 sensor with the wrench and unscrew. Reverse process for installation.

the o2 sensor is located in the exhaust manifold. As you pop the hood and look at the engine, you should see a silver colored heat shield. Unplug the old O2 sensor. Then remove the heat shield. Its easier this way (10 MM bolts). Get a O2 sensor socket and remove the sensor and replace. The rear sensor is located in 1 0f 3 places. Either before in or after the catalytic converter. For this one you just get the O2 sensor socket and remove. (When the engine is cold) Madd Dogg 40/40
