I have a 2007 Sport Trac 4.6L, 42K miles. On cold start-up it makes a chirping sound somewhere in the accessory drive area. I asked the local dealer what they thought it might be and they said it was definitely the serpentine belt. So I bought a Goodyear Gatorback and installed that. No change. I next replaced the belt tensioner. Noise is still there. Very annoying. Anyone else experience this or know what the culprit might be?
