oxygensensors.com tells me I need to remove seats to install sensors?
#17
I didn't take pics of underneath, because all the work was actually much easier, because the sensors are right there on the side of the exhaust, and because I was covered in black ****. But they all came off without much trouble even after 200K miles (still originals, btw). I had to buy a sensor removal socket (7/8", but they are all the same size as far as I can tell) - just a long socket with a slot cut in the side for the wire to get into. If you have a set of large crows foot wrenches then that might also work, or you could cut off the sensor down to the bolt to get a regular socket on, if you only want to undo the old one. But I would say for this year, you need the sensor socket to tighten up the new ones anyway.
I put copperease onto the threads (supplied with sensors).
The connectors came apart without much trouble (comparatively, since on vehicles there's just no such thing as a connector that is actually easy to undo).
I was having a hard time getting a ratchet onto the sensor socket while up there, until I remembered the 1" hex shape of the socket stem, which let me get a wrench on from the outside, and that proved to be much easier than the ratchet. Hence I didn't torque it (to 35 ft lb), I just guessed on that part. You need to collapse the gasket and then some.
Took me total 5 hours (and I'm no mechanic) including a trip to autozone, oil change, and lunch and a beer or two. 2/10 for difficulty. Vehicle runs fine - I'll see if the light goes out over the next few days.
