The Alternator Belt Is the Lifeline for Many Engine Accessories  

The alternator belt is one of the most important engine belts your car utilizes. Without the alternator belt, many of the functions your car performs would simply be impossible. In many ways, the alternator belt is the extension cord that supplies electrical power to your vehicle.

If you didn’t know what the alternator belt was before this, or just want to enhance what you already know, keep on reading. We think you will find this article helpful.

The Alternator Engine Belt

Almost everyone has heard of an alternator before. The alternator is the component in your car that is responsible for sustaining the charge of the car battery so that it can power the rest of the electrical accessories in the car.

When the alternator is doing its job, it’s actually spinning. But how does the power get from the alternator to the rest of the car? Well, that’s where the alternator belt comes in.

The alternator engine belt wraps around pulleys or multiple pulleys attached to the alternator itself. The other end of the belt is connected to the crankshaft. That way, the alternator, and the crankshaft can rotate simultaneously using the alternator pulley.

Without this belt, the alternator would not be able to do its job effectively. When it doesn’t work properly, you may run into problems with your:

  • Air conditioning
  • Power steering
  • Water pump

Physical Signs of an Old Alternator Belt

Over time, physical changes will occur to your alternator belt. Some of these can become hints whether your belt requires service. If you notice any of the following physical signs, consider scheduling maintenance:

  • Fraying around the edges
  • Cracks
  • Glazing along the belt
  • Abrasions
  • Uneven wear

Symptoms of a Bad Alternator Belt

Every single time that you drive, you are wearing down the engine components. This is true for the alternate belt as well. Over time, it will experience a great load of wear and tear. When this occurs, your car may display symptoms that should point you towards getting maintenance.

Flickering Headlights

IF you notice dimming for flickering lights while you drive, it could be a sign that the alternator belt is not working properly. The case may be that the lights are running purely off battery power. Eventually, without the belt running, the lights will cease to operate.

Engine Stalls

Another symptom of a bad alternator belt is engine stalls. This is when your vehicle loses power completely and shuts off. When this occurs, you’re forced to pull over and call for a tow truck.

Illuminated Battery Light

One of the telltale signs that your alternator belt needs replacement is the battery light becomes illuminated on your dashboard.

There are other reasons for this light to turn on, however, one of the most frequent reasons is because the alternator belt is no longer sustaining sufficient power to the battery>

Chirping or Squealing Noises

If the alternator belt is worn out and loose, you may hear chirping or squealing noises when the car turns on, and as it runs. This problem is normally made worse in cold weather. IF you hear these noises, it’s time to see a mechanic.

Dead Battery

Because the alternate belt is responsible or sustaining the power of the battery from the alternator, if the belt no longer does its job, the battery will eventually lose its charge and die.

Servicing your Alternator Belt

In general, we recommend completely replacing your alternator belt every 60,000 to 100,000 miles. However, every person and their driving habits are different. So monitor the condition of your belt when you can.

If you think you are experiencing any of the issues from above, it could be related to the alternator belt in your car. If you are unsure, you can always contact us for guidance.
