I am going to change the Catalytic converter on my 1997 chevy venture.
I am worried about removing the sensor without breaking it. Any
suggestions? Thanks.

Hello and welcome Jose, Sargent first class.
Thank you for your service to our country.
Assuming your are referring to the oxygen sensor, the best way to get those out is to soak
the sensor at the mounting point with a rust breaking lubricant. Let it sit for awhile, then
use your wrench to remove. It will be tight, but once you break it loose, it will come out
smoothly. If it cannot be removed while the exhaust is still attached and in the car, the
remove exhaust, put it on the floor, step on the pipe, and use plain old muscle to remove
sensor.  If all else fails, a torch is always a good tool to heat it up enough to remove it.
If you do break the sensor, that is not a big problem, since the O2 is not very expensive.
Once again, thank you for your service.
I have answered a few question from military personnel in the past year, and makes me
very happy and proud to offer some help.
