Front and Rear 02 Sensors OBD1

[Mean Green]

I used the autozone rent a tool O2 sensor remover tool. Worked great!

I replaced my o2 sensors with these:

I used the 02 sensor remover as well, but found that heating them up first with a torch worked really nice. After you take the heat away, wait a few minutes and then try and tighten it! This breaks it free and then everyone of mine came right out no problem.

Well I got them out, was a huge pain in my arse. The rear o2 sensor was cross threaded making it a lot longer then I expected. Front was a lot easier after soaking it in PB Blaster and let it sit for 3 hours. I HIGHLY RECCOMMEND 22MM WRENCHES! A lot less likely to strip the o2 sensor which made it so much more difficult, I am just glad I did not have to torch the housings.

Just replace front and rear on my fiances car to pass smog. Used the Auto Zone rental [$25.00, refunded when you return it] crows foot attachments.

Once the front one is loose you can put an open end wrench on it from underneath like Atrosity says.

If you use ARP Ultra Torque assembly lube on the threads it makes them real easy to install, plus it handles high temperatures and has anti-seize properties. Love mine.
