Magnum Serpentine on a '91 TBI 318? Without changing the intake?

Impressive sleuthing! Thanks!

Video is only a couple of months old, makes me feel better that I didn’t find it on my own.

Mine isn’t as bad as his was, but it is starting to sit at an angle like that. I’ve got a pretty good squeak going on, too. I assumed it was the air pump, but he mentioned that so maybe it is the tensioner.

Looks like he is running an alternator for a Magnum, too. Belt looks to be one rib smaller than the pulley.

Really appreciate it!
