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.

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).

Used for all 4 sensors on 03 diamante. 3 were good but I figured after replacing the first one, I'd crack and re-tighten the others just to prevent them from being frozen when they go bad. It worked so well I did it on my other cars as well. The only issue is retorquing to the 30lbs. With the offset you have to recalculate the torque wrench as a percent of the total length of the torque wrench with this device to the calibrated length of the wrench without the device. I found it was pretty easy to loosen the sensor when the engine was hot. I also found that it was easier if the ratchet handle and the tool flange were aligned and the ratchet handle didn't cross over the tool. Anyhow this works OK.

I broke it. The O2 sensor backed out about 1/2 a turn then tightened up. After using penetrating oil an turning in and out for an hour or so I used a long bar on it. It snapped in two after applying substantial pressure rounding off the O2 sensor. Had to take the exhaust manifold off, cut the old O2 sensor off and use a 1/2 impact to get it out...not really sure the whether product was defective or not. The O2 sensor did not want to come out. I don't do this type of operation very often (My first time) so my technique may have been a factor in product failure.

This Chinese item can be handy but if you have a frozen sensor you will still need a lot of heat or the Ox sensor will round off.
If the sensor is going to be replaced cut the top off and use a 6 point socket. AND LOTS of heat where sensor seats.

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.

It worked great. I used PB spray first and waited 15 minutes before using this since the van has over 105000 miles on it. First time worked on O2 sensor and felt good after it was done. Actually it took more time to connect and disconnect electric wire clip than O2 sensor itself using this item.

Made the removal of my 02' toyota avalon 02 sensors much quicker and easier than it would've been with a socket since one of the sensors was against the firewall.
