What Does an Alternator Do?

When you invest in your dream vehicle, like the Dodge Charger or RAM 1500, you want to do everything you can to keep it in top shape for dominating the Apex streets for years to come. Knowing the basics about your vehicle’s mechanical workings will help you stay on top of maintenance. If you’ve ever wondered, “what does an alternator do?”, you can learn more below with Hendrick Dodge Cary!

How the Alternator Works

The alternator is the heart of your car’s electrical system — the motor, battery, and alternator. What does an alternator do? It creates mechanical energy that charges the battery when the motor is on. Generally, you don’t have to worry about replacing the alternator for seven to ten years, depending on your driving habits when you travel from Carrboro to Chapel Hill. When you keep your car well maintained, it’ll help extend the life of your alternator. If you log more daily miles than the average Cary commuter, you might need to replace your alternator sooner.

Signs to Check Your Alternator

When you know what your car’s alternator does, you’ll better understand how to identify the signs that your alternator might need to be serviced or replaced. If you notice any of these issues, schedule an appointment with our service department without delay. If you ignore these signs and don’t replace your alternator in time, you could find yourself stranded.

  • Dim dash lights
  • Illuminated service engine warning light
  • Strange noises
  • Problems with electrical systems, such as automatic windows, power seats, etc.
  • Problems starting the car
  • Dead car battery

How Much is an Alternator?

A new alternator tends to cost anywhere from $500 to $1000. How much a new alternator costs depends on if you opt for a new alternator with a full warranty or a remanufactured alternator that might have a limited warranty. You can save money on your new alternator with our Mopar coupons.
