    2005-2010 V6 Mustang Tech
    I'm getting that squeak from the serpentine belt and an assuming it's a bad spring in the tensioner but after watching some youtubes it could be the harmonic balancer? Also, the belt is only a few months old and seems to have some slack, & kinda' wavers a bit as it comes up from the tensioner to...
