Ford Alternator

It's the sole responsibility of Ford alternators to generate electricity that powers your vehicle's internal components and electronics as well as recharge the battery so it can start your engine. An alternator works by converting the engine's rotation into electricity, but it's trouble if it fails unexpectedly. Luckily, it's easy to change an alternator on most models, and parts are in good supply and affordable when you shop at AutoZone.

In most cases, you'll get at least seven years abuse from your alternator before you need to consider replacing it. You might also need to change it sooner if you experience symptoms such as a battery light on the dash, slow engine cranking, a dead battery, or whining noise from under the hood. As well, you might see poor electrical performance from systems like power windows or your headlights.
