[s-cars] Replacing O2 Sensor??

The antiseize compound comes with the new sensor, either already on the
threads or in a small plastic packet.
To get the old one out, try one of the O2 sensor split sockets or a box end
wrench (if you can swing it in there). If that doesn't work (if it is really
tight, the split socket will just open up), start the car and heat up the
exhaust. If it still won't budge with a hot exhaust, cut the wires and use a
deep socket with a Johnson bar for leverage. I had to run the car and get
the exhaust hot to get my OEM sensor out. I also made a custom O2 sensor
socket by cutting a window out of a deep socket, leaving the lower rim
intact so it wouldn't spread. This socket also works well on the front
struts - you can torque the top shock nut while holding the shock shaft with
an Allen key.

Subject: [s-cars] Replacing O2 Sensor??
Can someone help me with the O2 sensor? I am wondering how best to get it
out. Should I cut the wires and put a deep socket on it? Or will a box
wrench do it? I never have a good time getting anything out of the
exhaust manifold. Is there an easy way?
Also, the Bentley manual indicates... The threads of the HO2S sensor MUST be
coated with an anti-seize compound. Does anyone know what this compound
is or where to buy it?
