Signs That Your Serpentine Belt Needs Replacement
Even if you haven’t reached the recommended mileage, it’s important to inspect your serpentine belt regularly. Here are some common signs that it may need to be replaced:

- Visible cracks or fraying: Inspect the belt for any signs of physical damage, such as cracks, fraying edges, or glazing (a shiny, smooth surface).
- Loss of power to accessories: If your power steering, air conditioning, or alternator isn’t functioning properly, the belt may be slipping or failing.
- Dashboard warning lights: A failing serpentine belt can cause the alternator to stop charging the battery, triggering warning lights on your dashboard.
If you notice any of these signs, it’s best to have your serpentine belt inspected and replaced by a professional mechanic as soon as possible to avoid further damage to your vehicle.
