Automotive Oxygen Sensor Socket Removal Tool Wrench and Thread Chaser Set 5Pcs

I just used this set to replace all 4 oxygen sensors. The socket was sturdy and withstood extreme force as I used a breaker bar and arm extender bar to remove the upstream right sensor. It broke free, and I was able to remove the sensor. As this is common in the Midwest when removing anything that is exposed to the elements; I can say I have used other oxygen sensor tools that expand, break and round off the sensor or the socket. This set worked well without issue.The down side to the set in this particular case was when I had to use the thread chaser to repair the threads for the new sensor. The thread chaser failed to repair the thread. And failed to adequately cut through the corrosion at all. After further inspection it appears not to specifically be designed to recut a thread as much as it clears out minimal damage and corrosion. The thread chaser only had an issue with the upstream right. I finished the job with tap and die set.Overall the offsets were perfect for the downstream sensors and for tightening. All other sensors were replaced with ease.

arived fast and work like they should. as good as the more expensive brands.

This tool is a must have in your tool box if you ever plan on changing a 02 sensor. Often hidden in hard to get to locations along with little room to remove, this tool will do the job. Great quality at any price .

Work perfectly as announced. Great product. Decent quality. The protection box is good quality. And really has everything you need for a o2 sensor change.

A must have to removing O2 sensors, especially lower ones. Perfect to allow easy breaking loose of sensor from pipe. Had no other tool in shop that could have fit the space and allow torque needed r to break free.

Great price easy to use ,would be nice gift too!

I bought this set to remove the passenger side o2 sensor on a 1994 Ford Ranger 4.0 l v6. This sensor can be removed by working under the truck, but there is very little room to maneuver. The 7/8" Extension Socket (ES) in the set was of no use because the interior is partially narrowed, preventing a fit to the large body OEM Bosch sensor. I had to use the HB freight ES with a hose clamp on one end and an open-ended wrench on the other just to loosen the sensor. However, the set came in handy as it contains an offset Socket with 3/8" drive which, along with a 12" racheting breaker bar, worked better than expected in removing the sensor from the exhaust pipe. If you don't have PB blaster, a combo of nail polish remover (or acetone) and cutting oil brushed around the threaded area is incredibly effective in the loosening stage.

Worked great
