Well at the VEEEERY bottom of the motor between the crank pulley and the compressor pulley was a goddamn tensioner pulley. It didn't LOOK like one as there was no bolt-tip on the top of it to crank on, rather it was mounted on the back. I had to actually use my HANDS to pull it down and slip the belt on.
I've NEVER seen something like that before. Fucking bolt on the BACKSIDE of the pulley where you can't see it. You'd hardly know it'd move.
But it's taken care of. I appreciate it.
