Rust Penetrant
Copper Anti-Seize
22mm Wrench
Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Remove the downstream O2 sensor. I'm going to follow the wire up here and unplug it from the connector. There's a white part on the connector, and I'm going to push in to unlock it. Pull the gray part out. Now I can work on getting it out of the exhaust. Spray some rust penetrant in here. The exhaust is pretty cool. It's a 22 millimeter, so I'm going to slide the box end over the connector and down. There's actually enough space to get a wrench in here, so maybe use a spark plug socket. Give a good pull. Once it breaks free, I'll just unthread it from the exhaust.
And replace the sensor. This O2 sensor is fine. We're going to reuse it. If you were replacing the exhaust, you could take it out and put it back in. But I'm just going to put a little bit of copper anti-seize compound and then reinstall it. I'll wipe off the extra rust penetrant so it doesn't get smelly when the exhaust heats up. And install our sensor. Get it lined up. Just thread it in by hand. Put the box end through the connector. Tighten it down. Just want to feel that gasket squish a little bit. That's installed. The final step: go up, plug it back into the connector. It clicks. It locks into place.
