Squeak under the hood

[gtsingh91]

so when i start my car up in the garage in the morning when it's a little cold, it squeaks and sounds like it's coming from the serpentine belt. ive noticed that it has slowly gotten worse beacuse it would squeak for a little and tehn go away but now it doesn't really go away and it's noticeable. could it be a tensioner or a pulley or something? how hard could it be to tighten since there's barely any room there? TIA

It has an auto tensioner. Check it for tension first, if it seems good replace the belt.
