Best tool or trick to remove O2 sensor 1?

[sabresfan]

I removed the fender liner and found it to be pretty tough to get a wrench on the O2 sensor. Is there a trick or tool to make this job quick and easy? 2007 Xterra sensor 1 bank 2

thanks!

o2 sensor socket
universal swivel
12" extension
ratchet
access it thru the fender well (helps to remove the liner but not a requirement)


Also helps if you run the motor right before trying to remove the sensor. I usually hold the rpm at 3k for a minute before to help heat up the threads to try and stop the sensor pulling the threads out of the manifold.

ps take your time... half turn at a time to help save the threads on the manifold

Good Luck!
