There are some tops for removing it in the thread. I think generally I use a ratcheting box end wrench and/or a 1/4" drive socket with a short extension past the belt, 1/4" to 3/8" adapter, 3/8" drive ratchet with long handle.
Thank you Salim for the link. The tension adjust setup in the 2nd photo looks different from mine: yours appear to be easier to access to.

Now, my understanding is that the tension lock bolt (#2 in my photos) is a long bolt that goes through the sliding block, then the (sliding) guide plate and then the alternator's mounting ear's thread hole. In this case, the long #2 bolt doesn't budge on my hand force points the bolt is likely rusted badly in the thread hole on the alternator mounting ear. I need to get penetrating oil onto this thread hole.

I am getting closer.

Use heat. One and done.

I had mine crumble under force, seems like some galvanized bolt. Don't be surprised if you have to replace it.
