The front O2 sensor is located at the bottom of the heat shield just
before you get to the exhaust. It has a wire connected to it. You will
have access to this from the top of the car.You may need a O2 sensor
tool that you can borrow from most major auto parts retailer. Disconnect
the battery first then unplug the sensor. Using the O2 socket remove
the sensor. The sensor should come with a packet of anti seize, apply it
to the threads and install it. Plug the sensor back up and connect the
battery and you should be done.
