ac compressor squealing after belt removal
i was tracking down a coolant leak this morning on my 3.0 and I had removed the belt to check the water pump. after I was done and reinstalled the belt, I got a very nasty sounding squeal/screech from the ac compressor. I know it's the compressor because when I turn the ac off the noise goes away. I don't know why it's making noise but I need some suggestions on what I could do to fix this

Loose belt, tighten the belt and it should go away.

If the belt is loose meaning the adjusting pulley is bad. So, you cannot tighten the belt manually.

You only hear it when the AC is on because the clutch turns freely when the AC is off and has resistance when the AC is on causing the loose belt to scream--tighten me.

As I mentioned above, the tensioner (adjusting) pulley will do that for you if the thing works properly. You cannot do manually adjust or tighten the belt.

so these tensioners that comes on our cars are 1 time use? because this is the first time I loosened the belt since switching to a hydraulic tensioner

that's what I thought. I have maybe 20k miles on it so I doubt it has failed
