Insert the square tip of a 1/2-inch socket wrench into the square hole in the center of the serpentine belt's adjustment pulley. The adjustment pulley is the smallest pulley the belt wraps around.
Pull the adjustment pulley toward the engine with the socket wrench to release the tension on the serpentine belt, then pull the belt off the air conditioning compressor's pulley.
Remove the bolts which secure the air conditioning compressor to its mounting brackets with an open-end wrench, then position the compressor to the side of the engine compartment. Do not disturb the hoses that attach to the compressor.
Pull the electrical connection off the crankshaft sensor.
Remove the two bolts that secure the crankshaft sensor against the engine with an open-end wrench, then slide the sensor out of the engine.
Slide the new crankshaft sensor into the engine, then install and tighten the sensor's two securing bolts with an open-end wrench.
Press the electrical connection onto the crankshaft sensor.
Position the air conditioning compressor against its mounting brackets, then install and tighten the compressor's bolts with an open-end wrench.
Pull the serpentine belt's adjustment pulley toward the engine with the socket wrench, then position the belt onto the air compressor's pulley.

On Bonnevilles (1996 SE ), the belt is routed around the front engine mount to get to the air conditioner accessory. Once you turn the tensioner counter-clockwise using I believe 5/8" socket with a 1/2" drive breaker bar, so you have good leverage, you can remove the belt from the accessories. The front engine mount has three legs that connect to the front of the engine (on the passenger side of the car). You have to unscrew the lowest of the three mounting points (easiest done from the under side of the car, with the plastic shielding moved out of the way), which is right next to the crankshaft pully. Then there is a round tube spacer in between the engine block and this leg of the engine mount that you take out, and you can pull the belt out through there.
