2000 SE, trying to replace the 2 sensors closest to the radiator. HELP!!! Trying to do the first one closest to the radiator first, but I can't even put a wrench on the damn thing. There's NO room. What's the trick? Are there elbow wrenches out there?

The ac pipe is blocking. If you loosen the screw on that pipe down by the compressor, you will have enough room to slip on an o2 sensor wrench. Don't take off or loosen too much but you will see. You will need swivel adapters to actually turn it.

Think some crowfoot wrenches will help in this situation ... will keep everyone posted on the outcome. The right O2 sensor was a pita as well, but got her done, still need a crowfoot wrench to tighten her down.

Any luck on the removal?. I'm in the same situation.

Spent a good portion of the day fighting with the darn thing, but in the end, I won the battle. The front B2 o2, nearest to the radiator, definitely needed a crowfoot wrench, there was NO room for anything else. I used a socket wrench with a flex head, and a mini sledge hammer. Took a few whacks with the hammer ... don't forget the PB blaster b4 hand. One of these o2 sensor sockets may work for ya, http://www.walmart.com/ip/22978211?w...214196&veh=sem, but it did not work for me, for there was a dent on the body of mine, so the socket wouldn't go over it. Depends which brand of o2 sensor you're using, an o2 socket is needed for the final torque. The new Bosch sensor had a narrower wrench contact surface, and the heat shield gets in the way.

I got the front B1 off with a regular 7/8 open wrench, the hammer came in handy as well. But I used the crowfoot wrench for the final torque. It's best to remove the passenger wheel, and the plastic cover covering the compressor belts. The worse part was fishing the sensor itself behind the engine by the firewall. Probably should've just cut the wire, but I wanted to see how it was routed.

This one tool may be all that's needed ...
