Wow...really? First of all which oxygen sensor are you wanting to replace? Secondly why are you replacing it, its only been 6 years. Anyway this is the way to do it.
Rent an oxygen sensor removal tool from an autoparts store for a 50 deposit. Or find a good crescent wrench to take it off. If its rusted on there your going to need a torch to heat up the sensor for easier removal.
Most important thing of all is though. Are you getting a direct plug in or a universal?
Diret plug is bout $150 (easy plug in like 'yoru old one)
Universal is bout $50 (you have to cut and rewire the 4 wires)
Process...
Find the sensor
Take your torch and heat up the sensor directly with the fire
Take your wrench set it over the sensor and unscrew it
Unplug or cut wire...whatever you chose
Replace...sensor and...make sure wires are soldered back or pluged in
Congrats your done. Hopefully you did it right and didn't have a check engine light!

the sensor is in the gas tank. you probably need to replace the sensor.

The coolant temp sensor on a 2003 Chevy S10 V6 is located on the front of the intake manifold. To replace simply unscrew the old sensor and screw on the new one.
there should be little screws that you screw out and they pop out and you twist the bulb to remove it
on the dash to the left of the heater vent, peiece is held down by clamps just pop loose lift to access the sensor
The knock sensor on a 2003 Impala v6 3.4l engine is on the side of the block. The sensor is mounted just above the oil filter.
I dont believe the Impala 2003 uses a DPFE sensor as part of there Emissions system.
