A squeaky belt is usually caused by a bad belt, a missaligned pulley, or something leaking on the belt.
Tighten your tensioner pully. there should be a little bolt on one of your pullys.
Either the belt is worn out or the tensioner is defective.
Your local auto parts store should have several different brands in stock of belt dressing for squeaky drive belts.
oil it or shoot a squealer
although you may use a bar of soap to dress the underside of the belt, there is available a dressing for this purpose but check the belt for wear and stretch, you may need another one.
Yes, as long as there is no damage to it
Sounds like a belt or belt tensioner needs to be replaced
Replace with Good Year Gatorback belt. Costs more but worth the money.
check for glaze on belt, if ok spray the belt on the top side when running, with belt dressing, and pulleys if possible.
It could mean the beginning of the end for your belt or the idler pulley, have them both checked out.
