Some C, K, and R trucks with 7.4L engine and serpentine belt system may have a belt noise/wear condition. This condition could be caused by a
misaligned serpentine belt system. In a properly aligned system, the belt should be close to the center of the tensioner pulley, and the pulley should
extend past belt edge both front and rear.
