Having problems with your Cars & Trucks ?
2004 1.8t squealing once engine warmed up - Cars & Trucks
Is this the accessory drive belt that is noisy? If so check the belt edge for frayed or exposed cords like a tire cord, if that is found you have a defective pulley Or a crank pulley that is moving outboard due to the harmonic damper coming apart, this causes the belt to not run true across the pulleys and that causes noise..
