Location/Replacement of O2 sensor - 03 Oldsmobile Silhouette 3.4L

Was getting a code for bank 1 sensor 1 O2 sensor and needed to be replaced. Once replaced, the code went away. Tips: Invest in O2 socket or cut wires on old sensor to remove. ensure new sensor has anti size on threads but DO NOT get antisize on sensor. Sensor removal may be made easier is vehicle is warm, just be careful not to burn yourself.
