Buick 3800 Engine Crank Postion Sensor Location

Question:
Buick 3800 V6. Hello, can you describe how you change the crank sensor on this engine. I think this is the problem Ive been fighting. Where is it located? Thanks for your help. I made a small tip/donation.

Answer: See picture below.
OK, thank you !. I would suggest a technician performing this repair. Here is why.....
1- remove belt
2- remove crank pulley using special puller. Also, common for rubber damper inside pulley to shift and block the holes that the puller needs to screw into. Also may have to remove/loosen front lower engine mount(if it has one) and/or lower the frame and support frame engine assembly to gain good access to the pulley.
3- remove plastic shield
4- remove sensor.
5- sensor will have to be adjusted with another special tool as not to het the steel vanes on the inside of the pulley when engine running
