How does one "bring the lock carrier into the service position"?

Does the "copy and paste" function not transfer images as well? If not, why not attach the images since there are
references to them in the above post?

Brnblume123. Not sure if you still need help.

Remove the Serpentine belt. Remove mounting bolts for a/c compressor, remove compressor from block and tie / support
out of the way (under the car). Remove Alternator mounting bolts, remove alternator from block and disconnect wiring. Remove
alternator from under the vehicle.
