How do I know if a belt tensioner is bad?

One common symptom is unusual noise, such as squealing or chirping sounds coming from the engine, which often indicates that the belt tension is going bad. Also, visible wear and tear on the belt itself might suggest that the tensioner isn't maintaining the correct pressure. Another sign is the alternator warning light appearing on your dashboard, often a result of a loose belt causing charging issues. Performance problems like difficulty starting your vehicle or a decrease in accessory functionality can also point to a malfunctioning belt tensioner.
