Serpentine belt is squealing I believe. Car is at 109k miles so I figure I need to replace this, but wanted to get some insight first. Any way it just needs tightening, or would it do me better to just go ahead and replace it?

TIA

Belts are cheap, just replace it.

Yup. Time to replace it. Check the pulleys too. Especially the tensioner.

Serpentine belts usually don't need tightening. If the new belt doesn't fix it look at your pulleys

Get a quality belt like a Gates.

Pedal to the metal - only solution.

Some belts DO need tightening. This happened to my old car and I just had it tightened. Was a cheap fix. It'd be a good idea to check the belt for cracks though and see if it needs to be replaced.

What makes you think pulley instead of belt?

Well you can look at the belt and see if it's bad/cracked/frayed.

Squealing is usually (not always) the pulley/tensioner.
