Works great.

Definitely the tool for the job under my first-generation Mercedes ML320. Managed to get O2 sensors out for backpressure testing without removing either suspension torsion rod, although there was barely enough room for my hands/arms. This product fit securely and let me break the O2 sensors loose, so it probably paid for itself in time saved after two uses. Seems tough enough to outlast me.

Works very well, made a tough job a quick and easy one.

This tool works wonders for me. I was able to remove the post-catalytic converter oxygen sensor quick and easy on my 2008 Pontiac Grand Prix. No WD-40 or heating with a torch, came off with the exhaust slightly warm after waiting to cool. This surprised me after reading horror stories of others stripping threads, breaking sensors, or not being able to remove it at all. The offset 3/8 inch connection provides leverage and gives you the mechanical advantage needed to get it off. In the end, this tool did its job and looks to be good for many more uses.

This tool is a "must-have"!

This tool is a "must have" to replace oxygen sensors. I was getting fuel mixture error codes on my high mileage 2001 Silverado pickup. I replaced all four oxygen sensors using this tool. I sprayed the existing sensors' threaded connections with PB Blaster (it's like Liquid Wrench) a few days before I did the work. This tool has a cutout that allows the socket to pass over the wires of the sensor, and then move into place on the sensor head. A ratchet with an extension fits into the square hole on the tool. All of my sensors were really on there after 200,000 miles, but the tool loosened and removed the sensors with relative ease. On my truck, with the locations of the sensors, I don't know how a person would be able to replace them without this tool. It's all work from under the car, but I saved a lot of money buying the sensors and tool on Amazon, and the motor in my truck is running like new...no more error codes or rough starts.

Made this non gear head's life pretty easy

I'm not a gear head and prefer others work on my car. But a recent move to a new city and a very tight budget forced me to do more than I'd normally like. Where we live requires cars to pass an emission test - that hasn't been an issue in the past. Well the day before I had scheduled the test my diagnostic light came on. The test facility told me it was the O2 sensor - they could repair it for $X or he said it was a fairly easy repair to do myself. He even showed me where the sensor was on the engine and what I'd need to do the work. This tool made the job so easy - the mechanic had warned me that these offset pullers can have difficulty if the O2 sensor is seized in the socket. It was slightly but I didn't have any problems getting it to loosen.

Handly little tool

Great part to help you change your own oxygen sensors. I know these do the job for before-cat sensors. Some setups don't even require this, but my 2010 Toyota Rav 4 did and this part made the difference between having to drive to the mechanic and pay $100 for a job that I don't know how they did to doing it myself and knowing I did it right. I don't claim to be a mechanic but I do prescribe to the notion that if you are well informed and mechanically inclined, you can do your own car maintenance, including changing filters, sensors, oil, and perhaps other items that don't require the car up on a lift or multiple people to get the job done. However, for regular maintenance, sensors, filters, and oil is about all that most cars made after 2000 require. Don't' quote me on it, but most modern cars are closed loop and don't require the tune ups that older cars did.

02 sensor removal/ install

works well. cheap. use 3/8 breaker bar to loosen. warm up your engine for at least a 30 minutes,remember to use liquid wrench to loosen before. let it soak for at least 20 minutes. spray again. disconnect the wiring harness. don't let it twist. left turn to loose , right turn to tighthen. use anti siege that come with your new 02 sensor. do not get it on the o2 sensor, only the thread. 30lb torgue to tighten. (after finger thigthen, 1/ 2 turn with socket wrench it should be 30lbs).

Very good tool for O2 sensors

This tool did a great job. I read negative comments about full size socket that they might cut off or damage wires so I decided to go with this short range and no regrets. I didn't even warm up my car and the sensor came off easily. The most difficult part was to disconnect electrical connection. The trick part is: do not take off connectors out of the metal bracket. Just pry a small flat screw driver in the opening located on the side of sensor's connector to release the lock (you will find it because it is the only one out there) and push car's connector away from you. Then take sensor's connector out of the metal bracket. I reinstalled this sensor without any issues for about 5 minutes. It is pretty much the same as to replace a spark plug except you need to get under your car. After driving about 12 or 15 miles the engine light disappeared by itself.

Worked perfect

I just replaced all of my o2 sensors and this tool worked perfect, Ive actually had it for sometime just never got around to reviewing it. I do not get the negative reviews, I'm just guessing that out of frustration of not knowing how to use a tool properly it's easier to blame the tool than yourself. I have been building cars for 25 years and even have a 6 foot air lift in my workshop so believe me when I tell you, it's not the tool. I will say that some of the cheap o2 sensors run a shy short of the 7/8" mark which as some of the complaints stated will cause it to feel loose. So the moral of the story is buy quality products and never blame the tools unless it's you that are the tool.

Required item...

Purchased this item along with Oxygen Sensors for our 2003 Land Rover Discovery. I can assure you, had I not had this tool I would not have been able to remove the sensors. (3 replaced, one to go) This little jewel will take multiple repeated heavy strikes with a hammer without fault. That's what it took to loosen the sensors, and this socket tool performed like a champ. I honestly don't see how removing them would have been possible without it. Highly recommended if you value your time, and sanity.

Robust and worked perfectly

This O2 wrench adapter worked perfectly. I am always hesitant to buy this type of tool because there was a time when things like this were often made out of some kind of pot metal and they would break very easily. This tool has to be very strong to withstand the force that is often necessary to remove an O2 sensor and it is strong. I'm a big guy and I really put a lot of force on the O2 sensor with a breaker bar and a pipe extension and the tool held up beautifully. Unfortunately, the sensor was simply frozen so I just heated it up what some MAP gas and it came right out. In the past, I tried using a socket type O2 sensor tool but it was useless. It spread and slipped on the O2 sensor. But I didn't throw it out because I figured it could be used to reinstall an O2 sensor but when I tried that today, I saw that the socket was cracked from end to end! It may have simply been a very poor quality tool but it turned me off to the socket type O2 tools. This Powerbuilt offset tool worked like a charm. I have bought three Powerbuilt tools recently and I am very happy with all of them. One is a Honda crankshaft bolt holder which could easily break if it wasn't made well. It worked perfectly. I also bought a Powerbuilt digital torque wrench converter that I am very happy with.
