: o2 sensor?

Is there an O2 sensor on a 1987 Brougham with the 307?
If so where? I cannot find it!

pass side on the exhaust manifold right before it connects to the exhaust pipe. Just did one on an 88 from the top.

If you look in the back passenger side of the engine, you can see the electrical connector going to it. They're not hard to reach but are a bitch to get out. You need a special O2 sensor socket to remove and install it (properly) but if you cut the wire you can use a deep well to get it off and then hand tighten it.

Thanks guys,
I rented the tool but there is way too much stuff under the hood. I am used to 1980's volvos and sciroccos!:)

It was done and easy with lots of extensions and a u-joint

I did mine a few years ago, but from what I remember I think I just unplugged the last two passenger side spark plugs and put them aside so I could gain some access to the o2 sensor down there.

I don't remember much from that, but it shouldn't be too hard to replace it.

It was a pain for me. I had to use a cheater bar moving it one click at a time.

I used the u-joint on the O2 socket and from there I used the extensions so the ratchet would be above the engine. It worked perfectly, 5 min it was changed.

Go in through the wheel well, there is a rubber apron to move out of the way, but still a better angle. I was able to use a wrench.

Cheater sticks and extensions? How do you guys fit that down there? I could barely get in there with a 3/8 drive ratchet and the socket.

As I said I did use a "u-joint) (if that is the term), to change the angle of the extension. The u-joint I installed right on the O2 sensor tool

^They're called swivel sockets or universal joints, either one is correct. I don't have any and don't remember ever using one.
