When the vehicle's engine is running, it spins the crankshaft, which is connected to the serpentine belt. As the crankshaft turns, it drives the belt, which, in turn, rotates the pulleys attached to the alternator and other accessories. The alternator contains a rotor that, when spun by the belt, generates electrical energy through electromagnetic induction. This energy is crucial for keeping the car battery charged and powering various electrical components, from headlights to infotainment systems.

3. Follow Replacement Guidelines Following the manufacturer's recommendations on when to replace belts is vital. Timing belts often have a recommended replacement interval of around 60,000 to 100,000 miles, while serpentine belts may need replacement every 50,000 to 70,000 miles.
