I've noticed that If I press hard on the gas pedal I'll get a squealing belt sound from my TJ.  It's gone on for a couple of months now, and only happens when I really give it the beans.  There is a good chance that it's the factory original belt from 2005 (160k miles).
Is this likely a belt problem, or should I look into changing the belt tensioner as well?
