Remove sensor from block face
Install or Connect:

Install crankshaft position sensor to block face
Tighten bolts
Torque Value: 20-40 N-m (14-28 lb.ft.)

Install crankshaft position sensor shield
Connect electrical connector
Install balancer on crankshaft
Apply thread sealer GM #1052080 or equivalent to threads of crankshaft balancer bolt
Torque Value: 150 N-m + 76 (110 lb.ft. + 76 )

Install inner fender shield
Install tire and wheel assembly
Torque Value: 140 N-m (104 lb.ft.)

Lower vehicle
Install serpentine belt
Connect negative battery cable

This would take you several hours with the correct tools if you had a pretty good mechanical ability.
