Default Changing O2 sensor

I am going to change the O2 sensor on my car. It looks straight forward but I need to know if there is anything that I need to know before I dive into the project?

I just changed the PVC valve and my that was a tough little bugger to find when I didn't know where it was.

Cold engine, big wrench. Crescent will do.

Add a small dab of anti-seaze for next time, depending on how long its been in there it can be a bugger to remove. Spray some penetrating oil and let it soak.

" 1.The new sensor is supplied with anti-seize compound applied to the threads. Do not apply additional compound. " Thats from the bag the delco sensor cam in. Says if its removed to apply a thin coat of anti seize. Other sensors might not have it, but most recommend Delco.

I had the O2 socket, so it was just a pain to get the torque wrench in a postion to turn it. I couldnt do it with out an extension, and the firewall/motor got in the way a little but, but all in all, took 5 minutes.
