Serpentine belts should be replaced at recommended service intervals or more often if there are signs of wear, looseness, or noise. It's advisable to replace belt tensioners and pulleys with new belts to prevent slippage and premature wear. Accessory belts power key engine components and typically last 50,000 to 100,000 miles, but their lifespan can vary based on factors like road conditions and driving habits. Warning signs of belt issues include squealing noises, system failures, visible wear, or vehicle failure.
