I can't hear anything on the vid, do the pulleys turn freely? (I expect the p/s pump won't.....) I don't see any unusual movement there, but, if any of the idlers/tensioner feel 'stiff', it's bad.

They should turn freely and be silky smooth. The AC idler sounded a bit dry. The fan is connected to water pump. Rock the fan blade back and forth. There shouldn't be any movement. If there is, your water pump bearings are bad and that can cause noise. Again, silky smooth.
