Remove the engine cover upward - arrows - and then to the front.

Bring the lock carrier into the service position.
Remove the ribbed belt.
Disconnect the connector from the DF lead - 1 - and remove the cap - 2 -.

Disconnect the B+ wire - arrow - from the generator.

Mark the top of the ribbed belt and the running direction before removing it. Make sure the belt is installed correctly and pay attention to the running direction. If the belt is installed opposite to the running direction or is positioned incorrectly, the belt will fail!

Remove the upper idler pulley, lower idler pulley and the generator ribbed belt pulley tensioning roller and coolant pump.
Remove the bolts - arrows - from the generator.

Remove the wire holder - arrow - from the generator.

Remove the generator.
Installation

Installation is performed in the reverse order of removal. Note the following:

When installing an already used ribbed belt, note direction of travel marked when it was removed!
Before installing the ribbed belt, make sure all the components (the generator and the A/C compressor) are securely fastened.
When installing the ribbed belt, make sure it is properly seated in the belt pulley!
Remove the threaded bushings - A - from the generator housing approximately 4 mm in - direction of arrow -.

Attach the wire holder - arrow - on the back of the generator in the 9 o'clock position.

Tighten the threaded connections to the tightening specifications. Refer to => [ Generator Overview ] See: Generator Overview.
Connect the battery. Refer to => [ Battery, Disconnecting and Connecting ] See: Tools and Equipment Battery, Disconnecting and Connecting.

Observe notes for threaded connections of battery terminals. Refer to=> [ Battery Post/Terminal ] See: Battery Service and Repair Procedures Battery Post/Terminal.

Start engine and check belt routing.
Turn off the engine.

Since you provided no motor size, I gave you the service for the 2.5

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.
