There are a number of belts under the hood of your BMW 323i that are all working to aid in the operation of different components. The serpentine belt is one of them. Also known as a drive belt, the serpentine belt works alongside the tensioner, idler, and various pulleys that are located in the accessory drive belt system. The serpentine belt helps to send power to things like your power steering and alternator. The serpentine belt is important to maintain, because if it starts to have issues, a range of problems can occur with these systems as well as your engine. Squealing noises coming from the front of your vehicle might indicate misalignment or a slip of the serpentine belt. If your engine is overheating, this can also be a sign of a worn out belt. You should also look at the belt yourself to see if there is cracks or wear and tear on the surface. You can find an OEM BMW 323i serpentine belt here on our site.
