Okay i have found the o2 sensor but i cant seem to get it off!!

Does any one have any idea on how to losen those two bolts? the Bolts dont want to move at all.

You found it!!!!

I took off mine with a ratchet and a socket. Maybe you can try and apply some heat to it.

ethan12510 · 03-26-2007, 12:15 AM

Well first off where does it plug into? Second i have broken some sockets trying to get it off!!!

Third what size socket did you use and does the new o2 sensor come with bolts? Thanks

It plugs into a yellow connector near the cam sensor.

The 2 nuts holding it on are 12mm.

O2 sensor does not use bolts. There are studs threaded into the O2 sensor housing (turbine elbow) and the O2 is held on by the 2 12mm nuts. And no, a new O2 does not come with any new hardware, just a new gasket.

You better be careful taking those nuts off, if you snap the studs you will be up shits creek without a paddle. In other words, you will need to take the downpipe off and remove the turbine elbow and get a new one or have a shop remove the snapped studs.

Try using a penetrating oil like PB or like he said use heat, a propane torch should do the trick.

well i got one nut off but the other one is really stuck, maybe even stripped? What are my options?

Its the thing that connects your turbo to your exhaust. The o2 sensor is sticking out and back at like 45 degrees and has a 3 wire plug. The 50$ O2 sensors suck balls. Just invest in the better ones. You want the one that looks like a machine gun barrel on the end with all the holes, not the one that looks like a spiral of some sorts(bosch style)
