What Does an Alternator Do?

Alternator with flat drive belt at modern truck engine

Many Lee's Summit drivers are wondering, “what does an alternator do?” Well, the alternator has a very important job, especially on the vehicles you can find at Eddy's Mazda of Lee's Summit that are filled with the latest tech features. The alternator keeps your electrical components supplied with energy while your vehicle runs. 

A failing alternator can leave you with a stalling engine or dim lights which would be a nightmare on your Kansas City commute. Visit our service center to avoid any alternator issues and find the answer to, “how much is an alternator?” Be sure to also follow our service tips to keep your vehicle safer on the Independence streets!

How Does It Work?

As your car engine runs, the alternator charges the battery via an electrical current. The current is created through a pulley that produces mechanical energy. The serpentine belt controls the entire system based on the revolutions of the engine. Typically, an alternator can operate for seven to ten years without maintenance. However, adjacent parts like the rotors and brushes may not last as long. 

How Much is an Alternator?

If you are asking, “how much is an alternator?” you are not alone! This is a common question we hear at our shop. A budget-friendly option you can opt for is a remanufactured alternator. These will typically run from $300 to $500 and may include a warranty for one to three years. A new alternator may range from $500 to $1,000 but will often include a limited lifetime warranty. 

You can order parts from our Lee's Summit service center to ensure your vehicle is fixed up with genuine parts. We also offer many service specials year-round to ensure our customers get the very best deals possible!
