Which Serpentine Belt

[Rem152]

Hey fella's I have a quick question I'm getting some squeaking coming from my serpentine belt I have a 2006 Mustang GT with a 2.6 Kenne Bell and a 3 1/2 pulley I wanted to know what belt I would need or better yet what size.

Thanks in advance.

First check to make sure you're not bending a tensioner.
The belt size I can't help you with but I recommend the Gates Green Stripe Fleetrunner belt for long life and great performance.
Once you figure out what belt to run write down the info and keep a spare on hand.
