[s-cars] Installing a new O2 sensor, is there a torque value?

[Kirby Smith]

You can try running the cable through a box end wrench and seeing if you
can get enough leverage.  This worked once on my 90q.  A crowsfoot
wrench attached to a breaker bar would seem to be a viable option,
except the two sides of a crowsfoot don't provide a very good grip. 
Also, a big Rigid Stilson wrench might work; haven' tried it.  

For penetrating oil, try PB Blaster.  Kroil is good, but would take a
while to get a shipment.

If you use heat, heat the manifold and not the sensor.  This will
provide a slight advantage in thermal expansion.  

Be sure to spread the antiseize that comes with the sensor carefully. 
You want full coverage of the threads and ZERO coverage of the sensor
tip.

I was thinking since I'm getting rid of the old one I can just cut the wires and use a regular deep socket, and for installing the new one an open end wrench do fine unless it requires a specific torque setting... but I don't see why it would.
