Hello ford owners, I have this issue that started 2 weeks ago, when starting my car while cold and has been sitting for ~6 hours or more I get this loud screeching metal grinding kind of noise. the car is Ford edge 2013 with the Duratec 3.5L, it has 240k Km on the clock. these two videos can explain the noise heard. I don't think it's the starter because it only happens when the car is cold. it might be one of the pulleys, probably the alternator ? would appreciate any suggestions. thanks.
