When I auto start my truck it first sounds like clucking by the muffler, now the belt makes a whinting noise...but goes away after 15 minutes of driving
My car has 49000 miles.
My car has an automatic transmission.
It sounds like you could have a stretched serpentine belt, a dried out idler pulley, or a faulty belt tensioner. I would recommend having your engine inspected by a qualified professional to determine which one of these parts, if any, are causing this issue. Once the cause of this issue has been determined, I would recommend having the noisy part replaced to prevent further damage to the engines belt driven components.
