Telkwa Posted March 11, 2013 Report Share Posted March 11, 2013 They cleverly tucked the sensor into a corner where I can't get a purchase on it. Anyone got some hints on the right tool for the job? Quote Link to comment
metalmonkey47 Posted March 11, 2013 Report Share Posted March 11, 2013 O2 sensor wrench won't get it? Not the 1/2 drive socket craps but the swivel wrench everyone rents out Quote Link to comment
RedBanner Posted March 11, 2013 Report Share Posted March 11, 2013 Im negging you.... start a thread about that. Quote Link to comment
Telkwa Posted March 11, 2013 Author Report Share Posted March 11, 2013 I didn't know there was any such thing as an oxygen sensor wrench! You're referring to one of these puppies, not the crow's foot style that would be used with a ratchet? Quote Link to comment
datzenmike Posted March 11, 2013 Report Share Posted March 11, 2013 Doesn't look that hard. Quote Link to comment
72240z Posted March 11, 2013 Report Share Posted March 11, 2013 Depends how rusted and fused it is together. Heat the motor up and soak it in pen oil prior then use the o2 wrench and a breaker bar. Quote Link to comment
Telkwa Posted March 11, 2013 Author Report Share Posted March 11, 2013 Now that it's idling again (thanks datzenmike) I'll definitely heat it up and soak with Aerokroil. Let it cool a bit and do it again. Amazon has a bunch of Nissan 720 O2 sensors. This one appears to be correct (?). I don't know if our local stores will have one for such an old rig.

oldskoolvws Posted March 11, 2013 Report Share Posted March 11, 2013 I gots one of these and it works perfect. Kroil is your best friend, but PB blaster is a next if you can't afford or find. Quote Link to comment
Telkwa Posted March 17, 2013 Author Report Share Posted March 17, 2013 Lucked out and got a bite on it with a standard 7/8" box end wrench. I only had a few degrees of freedom to move the wrench, so if it hadn't broke free relatively easily woulda been a different story. Our local NAPA store had a Bosch replacement. I had to cut the old wire off and crimp to the Bosch, but they included a piece of heat shrink tubing in the box. That was thoughtful. Quote Link to comment
72240z Posted March 17, 2013 Report Share Posted March 17, 2013 Breaking one free thats bad so easily is extremely lucky. Maybe the last person who replaced it was smart enough to use anti-seize. Quote Link to comment
