🔧 Efficient Oxygen Sensor Removal Made Easy with Powerbuilt 648442 Sensor Sockets Review

I bought this socket to replace my own oxygen sensors on my car. It fits perfectly but if the O2 sensor gets stuck the bushing will actually flex and slip off. He just removed the sensor.

I'm not sure what the problem really is, but I couldn't unscrew the oxygen sensor that this socket was designed for. It kept sliding. I ended up taking the car to a mechanic and ended up paying over $100 to have the sensor replaced, which I was hoping to do myself and save some money.

This tool is useless if your oxygen sensor is old and very tightly attached to the exhaust pipe. Even after 3 days of impregnation with penetrating oil, this tool opens and jumps over the end of the lambda probe. I used a 22mm box wrench over the sensor and placed a jack underneath. It worked. I cannot recommend this remedy.

The steel on this bushing is not strong and the wall thickness of the bushing is too thin, allowing the bushing to flex around the perimeter of the oxygen sensor nut when screwed in Sensor nut for removal - Strip the tabs off the nut. Be very careful when using and let the sensor soak in the penetrating oil for a few hours before attempting to remove the sensor. Start the engine, spray penetrating oil, let it sit, and then try to remove the sensor.

So this is a 7/8 inch socket (judging by the stamp on it). I put it on the O2 sensor on my car and started trying to unscrew the sensor. The socket didn't fit very well, was dangling. It ended up stretching around the sensor and slipping off (my knuckles didn't appreciate that). I didn't use a breaker on it and it didn't burn out the sensor. I ended up having to use a 7/8" box end wrench to remove it (and it came off without heat, so the socket should have worked if it did fit). I haven't even…

What should have been a quick job, changing the O2 sensor became a lot more difficult - bore too wide/steel too weak and shaft kept splitting when I applied moderate torque . to remove the old sensor. It started with cleaning the sensor. I ended up driving to an auto parts store and bought one of the displacement sensor key adapters. I give three stars because after unplugging the O2 sensor it allowed me to remove the sensor and start a new one so it was still useful.

This socket is either the wrong size or bends too much due to too much wire gap and failed to disconnect the O2 sensor and also rounded the corners of the faulty sensor. My immediate workaround was to cut the wire from the sensor and remove it with a good quality regular Craftsman socket. This bushing had some utility in pulling the new sensor in, but the process requires much less torque compared to removal. Next time I'll use a wrench or buy a good quality socket and use an angle grinder to…
