Turn on vehcle and let it warm up. Be careful exhaust will be very ot.

With engine off locate oxygen sensor that needs replacement and disconnect the connector keepign it away from the hot pipes.

After that you will have to use a special socket or a box end wrench and procede to loosen it making careful not to strip it out or hit the hot exhaust.

When installing the new one use antiseize compound.
