Review on 🔧 Enhance Efficiency with Powerbuilt 648691 Oxygen Sensor Offset Puller by John Eaton

This could become a real project. You will definitely need these two tools: =oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 and if the project is like mine you also need this youtube has a lot of videos showing how to fit new o2 sensors. Each step can be a test. Just disconnecting the old one from the wiring harness isn't easy. Removing an old sensor can be a real challenge. It is useless to remove the offset bushing (item 1 above) but is needed to tighten the new one. Go ahead and snap off the top of the sensor and use a 22mm socket and a long jumper (it took me 2 1/2 feet to snap mine off) and you'll end up pulling out the old one. Unfortunately, the old sensor's threads will most likely remain in the connector, so fitting a new one won't work. If you're lucky an 18mm tap (item 2 above) will clean out the threads so you can screw in a new one. Not so fast - because most likely you'll have to buy an 18mm tap (item 3 above) and re-cut the plug. In my case that was the end of my injury but as you can see on the web there is still an option to use a helical thread repair or worst case scenario weld in a new plug. You will use the offset head to tighten the new one to about 14 ft-lbs of torque. I suggest you order all three tools so you're ready for your job. Enjoy!
