Should o2 sensor be removed when hot ?

I replaced mine cold and it worked fine. Came out easily. You are apt to burn yourself removing it hot.

I remove it when it is cool, don't want to break or bend the señor when taking it out.

I don't out of fear of striping the threads and burning myself, I use a o2 thread chaser with antisense on it then put in the new sensor.

Probably not; I removed mine cold, and then installed the new one. It worked perfectly.

It might be. Others have commented on short life for new thermocouple, operating temperature of safety sensor is different part numbers will vary. Sensor temp rating has NOTHING to do with thermostat setting for water temp!!! Be sure to clean the combustion air screen on bottom or around the base of the heater. Lack of air flow is #1 reason for thermocouple (sensor) failure. If you need owner's manual, go to aosmith.com & follow tabs to your model. I checked & it is available.

This is the answer I found on the net for your car: Your vehicle may be equipped with multiple oxygen sensors at various locations - it is suggested that all be replaced, or at least that all be inspected and tested.

Sensor must be removed to add air.So you must unlock to add air.I never use them . PitBoss.

It's only takes a minute to remove, but may be hot. Mine has been in a snowy climate, made sure to put cover on as soon as it cooled down.

Even if the oxygen sensor is disconnected it is unlikely to cause a misfire. The sensor only helps the engine management system decide on the richness or leanness of the mixture. A misfire is more likely to be a component or connection on a single cylinder. Probably an ignition part or a fuel delivery part.

No you do not. Ive had mine in place for a few years now without a sensor and everything's running great!

yes, but the o2 sensor should be pointed forward, bcuz it won't screw in the way it's pictured. Try looking at more options

On my car it's on/near the rear exhaust manifold within the engine bay. The 2nd sensor is on the catalytic converter. I bought a new sensor just to be safe when I had this part installed.

I can only speak to the experience I've had, with replacing the O2 sensor on a BMW. This sensor is plug and play with that car, nothing else needed aside from an oxygen sensor socket to complete the job.

No. It's not necessary to remove it. The ignition resistor wire (or actual resistor in some older cars) reduces the voltage to the points while running through the "on" position to increase their life. No more points and that resistance isn't necessary, but this unit works great without you having to make that change.

I would suggest removing it. The motor will run hotter not colder. A larger radiator is suggested also.

yes you can leave the sensor in long term, i have had my sensor in for about 6 months.

You bet!! Replace it as soon as you can. The hot could cause sparks, then fire! Good luck!

If the wiring is ok (Good ground and hot and neural are correctly wired) then the sensor may be defective.

It depends on the car and the software you are using with this code reader, but mainly yes. As least if it did not tell you which O2 sensor is bad it will tell you that an O2 sensor is bad somewhere.

I bought the oxygen sensor wrench that is paired up with the sensor. For less then ten dollars it was definitely worth it, made it easy to remove.
