Powerbuilt Oxygen Sensor Offset Puller, Remove and Install O2 Oxygen Sensors, Wire Gate, 22mm 7/8 Inch, 6 Point - 648691

I'm glad I went with this style vs the socket style. It's clear that this is a much more versatile way of getting into tight spots. This made changing my O2 sensor a breeze. The whole process took less than 5 minutes. This tool made changing the upstream O2 sensor simple and it is the only tool that will fit for changing the downstream/aft O2 sensor. If I had purchased a socket style socket I would have still had to purchase this one for my aft sensor anyway.I'm happy I decided to change the O2 sensor at the same time as changing the plugs on this car for my 100K service. The O2 sensor is right in the way of the #6 plug so changing the O2 sensor was a no brainer. It had to be removed to get that plug wire off anyway. Most people don't realize that the O2 sensor is a wear item just like their spark plugs and don't change them out every 100K. By the way, before anyone comments on my 100K tune up, please be aware that my vehicle used Iridium spark plugs that only need changing at 100K miles. Amazon saved me a ton of money on my O2 sensor too!I had no idea that my car wasn't performing at 100% until changing the plugs, wires, and O2 sensor. It idled smooth and had tons of acceleration, so I didn't notice anything wrong. By looking at the plugs that came out with 100K miles on them you would never know it. They looked almost new (The OEM Iridium plugs are awesome). However it runs like a Singer sewing machine now, and I wish I would have done this 10K ago. It's certain in my mind that this improvement is due more to the O2 sensor replacement than the plugs.Now if I can find a tool that makes getting those plug wires off easier. My arms are a bloody mess after wrestling with the plug wires between the engine and firewall on that car. My old plug wire pliers just didn't cut it for this application.

Did the job and worked great good value!

Used this to remove two exhaust sensers , used heat and penetrating fluid first and a hose clamp to keep it from spreading apart , not sure how many times it will last , main thing it worked for me !!

I was sure this dumb thing would be useless, but boy was I wrong. It WAS entirely useless on my truck, since the O2 sensors were welded in by a rust demon and were readily accessible with regular tools such as a hammer and my oxyacetylene torch, but it came into its own on my wife's 96 Buick Regal. The downstream O2 sensor has a rain/rock shield welded around 3/4s of it, and is entirely impossible to get a wrench on. This little guy popped right over the wires, slid over the sensor, and actually cracked the thing loose. Still was a bear to get out, since I didn't have clearance to do a full turn due to the size of the tool, but without it, I wouldn't have gotten it out at all.Good on you, offset 7/8ths socket with a slot in it!

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.

Very well made tool.Since I am replacing the CATs on my 1998 F150 I do not have to deal with trying to remove the sensors while the are still under the vehicle. But the tool does make the process of getting to the sensors a lot easier versus using any other kind of wrench, so I am sure I could have removed them while still installed. The real trick is getting to, and removing the electrical connector. They can be pretty hard to get to, at least on my truck, but it can be done.After applying a little heat to the area where the sensor is screwed into the pipe it came free pretty easy. Since the tool uses a 3/8" drive i used my 1/2" breaker bar with an adapter. Came out no problem.If you are removing O2 sensors, even if they are easy to get at, I would recommend getting one of these adapters. Makes the job a lot easier and there is little chance the tool will slip and strip the nut - which would be bad.Well worth the price.

I bought this along with an o2 sensor that I installed the other day. I will wait to review the sensor that I also bought on amazon after another 100 miles and the light doesn't come back on.. but this socket attachment worked like a charm. I had very very very little space to work even after taking off one of the heat shields, I should have taken another off but it would have been another 1/2 to do so. But this little guy did the trick. I kept thinking it was opening up and not allowing me to torque the sensor correctly - I was wrong. I didn't have the best toolset to work with to say the least. I ended up adding a small pipe to the end of the wrench to get more leverage and allow me to get in their tighter busting my knuckles. I was able to get it loose with 5% effort more than I thought would break it. So if it isn't budging - try a LITTLE bit more. Then I was able to get the other on rather easily too. I figure I saved about $200, maybe more by doing this job myself and not taking it somewhere. Goodluck.
