I'm installing a new header but I'm getting stuck cause i can't seem to disconnect the O2 sensor from my stock cat. I'm just trying to unplug the plastic part, not the part that hooks up to the cat. How do i unplug this thing??

 

well, can't i just unplug the electrical (plastic) part of it and then take the sensor part off the cat?

also, what size of the bolt of the sensor? it's like bigger than 18mm

 

use pb blaster. i dont know what size the bolt is. but i believe its smaller than 18mm. and yeah, it pita to unscrew that thing. just take time and go slow.

 

i picked up a o2 sensor socket at autozone, does wonders, there is a slot in the socket for the wire so you dont twist the wire off. and the size is 7/8"

if i remember correctly for the plastic part you have to kind of squeeze, pull and wiggle at the same time. for the bolt of the sensor use a monkey/cresent wrench.

 

that plastic thing is a PITA to pull out... should I pull on the wires? there seems to be two tabs that i can squeeze on.. how the h3ll do i squeeze two tabs and pull with only two hands?? arghh

i gotta get a bigger wrench now too for that sensor bolt

 

btw, thanks for all the help guys

 

7/8" Wrench

 

thanks for going to all this trouble dude, i'll let u know how it turns out. i'm going to try in a bit here.

 

That was awesome..... it dont get no easier than that. I recently had to un-plug mine, you need to get both hands up there, one to push on the tab while holding the top part of the harness and the other to pull the plug out..... its not that hard.
