I've been driving my 89 Chevy S=10 Blazer without knowing they need an
oxygen sensor every couple thousand miles. Ah, well.

4.3 engine. I finally found the sensor on the passenger side of the engine,
between spark plugs 2 and 4. Truck was bought about 120,000 miles and
presently has 265,000 miles. Might be time for a replacement sensor.

Question: Is it better to change the sensor on a cold engine, or on a hot
engine? And any practical tips from someone has done one?

Do good work.
It's longer in the short run
