    Squealing serpentine belt

    I just replaced the serpentine belt (Dayco I think) and it squeals at startup but it eventually will go *almost* go away. Blip the throttle and it comes back.

    Since it's an automatic tensioner, is this a belt thing, a tensioner thing, or a pulley thing?

    Thanks in advance,

    Sounds like a tensioner thing, especially if the belt is brand new. The tensioner should be very firm when you are trying to release pressure from the belt, if it isn't then that's probably your issue. I would definitely inspect the rest of your pulleys though to make sure they all look and sound okay.
