The sensors screw into threaded flanges on the exhaust pipe. There will be one before the catalytic converter called the "upstream" sensor. It will have the short wire. The second, or "downstream"sensor has the long wire and is located after the catalytic converter. You can purchase a special tool for removing the sensors. If the sensors are positioned so as to allow the use of regular hand tools, you may be able to change them without the special tools. It is best to change the sensors while the exhaust pipe is cold. A hot exhaust pipe will cause the threaded flange to expand, making removal more difficult.

It will be very much appreciated if you could send me the information about how to replace the O2 sensors on a 1998 chrysler sebring convertible.

Hello, Eventually your Chrysler Sebring's oxygen sensor will go bad and need to be replaced. The oxygen sensor regulates the oxygen-to-fuel ratio in your vehicle. It also controls your gas mileage. It senses when more or less oxygen needs to be pumped into the fuel lines. If it fails, your Sebring will run poorly and won't get very good gas mileage. Knowing how to change it yourself can save your money. Here are the instruction to change o2 sensors.
Locate your Sebring's oxygen sensor on the pre-catalytic converter. This is located near the front right wheel well of your vehicle. Apply some anti-seize paste to the threads of the new oxygen sensor. Be careful not to get any of the paste on the sensor itself, or it will be ruined. This makes for easy removal of the sensor next time.Remove the old oxygen sensor, using the 7/8-inch wrench. Find the stock sensor wire near the engine-loop lift. This will be by the firewall of your Chrysler Sebring. Splice the stock sensor wire and connect it to the new oxygen sensor's wire, using crimp connectors.Remove the large air-intake pipe that runs from the air box to the rear turbo. Then remove the two smaller air pipes that run from the air box to the blowoff valves. This will give you access to the oxygen sensor. Soak the old oxygen sensor in WD-40 to loosen it. Screw in the sensor by hand. Use the wrench to fully tighten the oxygen sensor so it cannot be removed by hand. Replace the air pipes to the correct valves again.

    Where is the oxygen sensor located? (i just bought this car and i dont know much about it)

    Depending on how many sensors this model has, you can follow the exhaust from the manifold and there should be one located close to the engine mounted in the manifold or exhaust pipe. If you have another one it will be after the catalytic converter on the exhaust.

    How do you install a oxygen sensor in a 97 camaro

    you need to remove the old sensor from the exhaust pipe with a box wrench, and the new one will thread in... there is also a wire which is longer and has a clip that needs to be undone also. remember let some penetrating oil work the threads because it is more then likely heat bonded in.

    Ok, the title didn't show all the question; and you ask if you can change the oxygen sensor yourself.

    The answer is yes, and it is very simple.

    There are actually 2 oxygen sensors on your vehicle, both are located on the catalytic converter. The first is located at the top of the exhaust coming out of the cylinder head, and the other is located on the underside of the vehicle on the same pipe coming off the engine. They look identical, except the underside has a much longer wire clip coming from it. Here is a picture of it.e4d9846.jpg

    Location of oxygen sensor

    All of your oxygen senors are located in your exhaust system they are 4 of them on this vehicle. They are all screwed in to exhaust pipes with wire connections on them. All that's needed to replace them is an oxygen sensor socket and a ratchet this can be bought at any auto parts store. Good luck and thanks for using FIX YA
