Drive belts, also knows as serpentine belts, are wrapped around a series of pulleys on the engine. You will know right away if your drive belt is becoming cracked or worn by the loud squealing noise. Once you hear this noise, it is important to replace your drive belt as soon as possible. The good news is, drive belts are made to last a very long time. So you may only need to replace one once during the lifetime of your Harley.
