How do you change the O2 sensor on a 1998 Ford Escort?

Answer 1

On the front of the exhaust manifold you will see your sensor, otherwise, it may be before the catalytic converter on the underside of your car, it helps to go out and buy a special wrench made especially for removing the O2 sensor. Unplug the sensor from it's wiring, then use the wrench to remove the sensor, don't forget to spray it down with a good lubricant such as kroil or wd-40 an let it penetrate for a few minutes before attempting to remove it.
