o2 Sensors.

**Black87GT** · 05-21-2008, 06:04 PM

ok well i was going to replace my o2 sensors today and have run into quite the dilema, well when i crawled under the car with a 7/8 wrench to take the left side off (on my header) i saw that it was pretty much well rounded off, so i was like oh shit, so i went an bought a oxygen sensor take off tool thing from advance auto parts, thinkin maybe it would get a better grip, well no luck it just basically spins on the nut on the actual oxygen sensor, so idk what to do? other side looks fine, but this side is pretty much rounded off..
What should i do?

If they are right in your headers you should try a big pair of vise grips..or a big pair of channel locks.

and some heat... and some blaster... and some heat. soak it with blaster, drive it around get it hot and cook it all off then soak it again. then try, probably gonna be a bitch.

It's a 3 sided Vice Grip wrench and not just vise grips.

**Black87GT** · 05-22-2008, 07:22 PM

well i just got the one off i couldnt yesterday, with a torch and vice grips, and then i went to the other side and i cant even get it to budge, with torch, or running around in the car for 10-15 min to heat it up, and this one is completely round now... no room to use a pipe wrench, and no matter how tight i get them vice grips just seem to slip now???

Just sprayed pb blaster on it, should i let it soak overnight and try again tomorrow, or should i go back out an try tonight??

I would keep spraying it, try it tonite, and if not really soak it and let it sit till morning.

**blizzard** · 05-22-2008, 09:00 PM

well it really wouldn't be that hard to take out anyway if you had to... but if you can (with the limited room) you can try to use a side grinder to flatten two opposite sides down... or even just get some good flat spots around it and go with the vice grips and torch again. and yeah, keep soaking around the threads withblaster... good luck...

**Black87GT** · 05-22-2008, 10:31 PM
