So I get a whining noise from the AC compressor from time to time when the AC is on.  I've tightened the belt and it goes away but  it starts to whine later. So too tight not tight enough?

If it's not the tension could it be the clutch?  Can I have the clutch fixed or just replace the compressor?

The AC works good, no problem cooling  its just the noise.

Thanks for looking.

How many miles on the belt?

Put a bit of water or some belt dressing on the belt. If it quits, replace the belt, it's likely glazed. Spin the idlers and see if they spin freely and feel smooth.

Is it a Vee belt or a ribbed flat type?

Belt is 2 years old tops, v belt, idler pulley is new, 2 years same as belt.  Truck has 177k miles, I'm sure it's the original compressor but bought it used so I could be wrong.

Wet the belt, if the noise changes, replace it. You may get away with a bit of belt dressing if it's glazed but it's a cheap belt.

If the belt is OK, replace the compressor.   If the compressor blows up, you will have to replace absolutely everything because the metal shreds will go everywhere.
