    Trying to remove the 02 sensor off the cat on 2003 360. What wrench size would be best for this job?

    They make special O2 sensor sockets.

    trying to use a wrench instead, but a 19mm isn't it.

    I think it's bigger than 19mm. I'm too lazy to go out and check.

    FWIW, using a wrench (assume open end) could result in a rounded off O2 sensor. I guess you could unplug the sensor and run the wire up inside the box portion.....

    I have the cat pipe off the car. I was told an open wrench would be best way. I can go to sears to pick up tools if need be.
