When do you change a serpentine belt on a kia soul?

You should change the serpentine belt on a Kia Soul approximately every 60,000 to 100,000 miles, or as recommended in the owner's manual. Signs that it may need replacing sooner include visible cracks, fraying, or glazing on the belt's surface. Additionally, if you hear squeaking or chirping noises coming from the engine compartment, it may indicate wear. Always consult your vehicle's manual for specific guidelines.
