What Does an Alternator Do?


Many New Rochelle and Mount Vernon drivers know that an alternator is a crucial component to our new or pre-owned vehicle, but what does an alternator do? An alternator is responsible for sending power to the car’s electrical system while the car is running and acts as a generator using the gas engine as its source of energy. With such an important function to your Kia model, it’s even important to learn how to take care of and monitor the health of your alternator.

Common Alternator Problems

One of the first ways you can keep track of how well your alternator is working is by knowing how to recognize common alternator problems. These can be early signs of wear or indicate that your alternator must be repaired or replaced immediately

  • Battery warning light appearing on the dashboard
  • Dim headlights or interior lights
  • Burning rubber smell under the hood
  • Devices not charging
  • Whining or screeching sound after the vehicle has started
  • Inability to start the vehicle’s engine

Failing Alternator vs. Battery

In addition to understanding the function of your alternator, you also need to know that sometimes you can easily misinterpret functions and signs of your alternator versus those of a failing battery. Get around this confusion by waiting until the vehicle is unable to start and see if it needs a jump. If your vehicle dies immediately once you jump-start the engine and remove the jumper cables, the problem is likely your alternator.

How Long Does an Alternator Last?

Since the health and quality of many alternators depends on the driver and how often the vehicle is used, it can be difficult to determine how long it can last. A good assumption to use is that most will last between 80,000 and 150,000 miles or about seven years. Here are some reasons why an alternator may last less time than it should:

  • Alternator quality
  • Driving conditions
  • Power drain on the alternator

How Much is an Alternator?

When it’s time to replace an alternator, the first question you’re bound to ask is: “How much is an alternator?” Due to the fact that different alternators are used in different vehicles, the answer to this can vary for every customer. Be sure to check with your local dealership to make sure that they have what you need in stock and can install the part correctly.
