Toyota Alternator

Under your Toyota's hood, the alternator generates electricity necessary for your vehicle's electrical functions. It converts mechanical rotation into an electrical current that both powers your electrical systems and replenishes the battery's stored charge. Over the years, the alternator can slowly degrade or quit working suddenly, and you'll need to get it repaired. A replacement alternator is the best course of action, and AutoZone has a wide range of Toyota alternators to fit.

On average, you'll get between seven and ten years before an alternator starts to fail, although it could be much sooner. If your Toyota's alternator is on the way out, you'll experience symptoms such as a battery light illuminated on the dash, smoke from under the hood, whining or whirring noises that change with RPMs, or electrical issues like flickering headlights.
