Belt aging engine belt is made of rubber, glass fiber and steel wire. Over time, the aging of the belt material will reduce the elasticity and tightness of the belt, so it will make noise during driving.Two. The belt is too loose. When the engine belt is loose, it will cause the belt to mismatch the pitch of the pulley, resulting in a hoarse or sharp sound, accompanied by vibration. 3. The belt is too tight. When the engine belt is too tight, it may strain the bearings of the engine accessories, and may also accelerate the wear of the belt, resulting in noise. Four. Dusty or oil-stainted vehicles often drive on the road and are vulnerable to dust and oil pollution. A large amount of dust and oil will have a negative impact on the belt, because it has the ability to wear the belt. 5. The pulley is damaged.
