Tools to remove an o2 sensor

[mramc3]

Whats the best tool to remove the o2 sensors?

O2 sensor socket, pb blaster, 1/2" socket wrench and a breaker bar.

be sure to get a metric o2 socket cause advanced auto parts only had a 13/16 that only stripped mine so i ripped the pig tail off and threw on a metric deep socket. Then just install the new one with the 13/16 being careful not to strip it yet get it tight.

BE VERY CAREFUL! I stripped the threads off my O2 sensor and had to run with it open for a while until i could get it re-tapped.
