O2 Sensor Replacement question
Hello everyone.
I am attempting to replace the O2 sensors on both driver and passenger side of my 95 LT1 coupe (P class engine).
Ok, this is silly, but its my hurdle that I would welcome suggestions on. I cannot access the O2 sensors with a wrench. My 22m open end wrench cannot access either o2 bolt because of the other things around that area of the engine compartment (trying to access it from under the car). The wrench just cant grab it.
I cannot find a 22m flex open end wrench to purchase. That would seem to be what I would need as a tool.
Maybe I am going about this in the wrong way.
Ok, my question. To those who have done the O2 sensor replacement task, how did get them off?
Thanks.

Just did mine and had to use a couple of different wrenches. I got a couple of them out with a big 7/8 open end wrench and one with a regular O2 socket. The other ( pass. side front if I remember) I couldn't get the O2 socket on because there wasn't enough clearance between the floor and the sensor to get the tool over the top of the sensor or swing a wrench either. I had a 7/8 inch box ratchet with a Z shape that would fit that position but the connector wouldn't fit through the hole in it. Then my Son said, "Dad, that's the old one, just cut the connector off!" (Gets his smarts from Mom
) Cut it, Z shaped 7/8" box ratchet wrench fit right over & got it out. Tightened the new one in with a small channel lock. A lot easier going in than coming out.

Update
Thanks guys.
The socket was a much better idea than my previous current path.
The problem now is that the socket does not have enough horizontal length on the arm to clear the exhast pipe.
I will keep looking for others.

Be sure and use anti-sieze compound (it should come with the new sensors) when you install them. You'll probably have to remove the knock sensor shields, too.
If so, I'd disconnect the battery to avoid creating an electrical short in your starter system.
Finally, the pigtail connectors on the 02 sensor wiring harness tend to get brittle from the exhaust heat. If you break one (easy to do) NAPA sells replacments.
