Engine chirping

I have this consistent chirping/ squeaking sound coming from my engine when my truck is in idle and when driving I am not sure what is it.

Anyone have any ideas?

Something around your belt, maybe the alternator pulley. Try spraying a lubricant on the pulley bearing and see if it temporarily goes away. If there is oil or coolant on the belt, it'll chirp when you shut it off.

Idler, tensioner, fan hub, pull the belt and try turning each by hand feeling for vibration, could be the alternator or ac compressor too, but most likley the idler or tensioner.
