How long does a rebuilt alternator last

When drivers think about the electrical power of their vehicle, they often think about the car battery the most. However, the battery produces the least amount of power for a vehicle.

It is the alternator which is really in charge of powering the main electrical accessories and features of a vehicle, such as its radio, air conditioner, lights, and so on.

All the battery does is produce the electrical charge needed for the ignition to take place when you start the vehicle. After that, the battery may serve as an electrical reserve in case something goes wrong with the alternator’s power flow.

But overall, the alternator is the king of a car’s power source. It is the component that keeps the car running after the battery helps start the engine.

How Long Do Alternators Last?

Alternators certainly last longer than car batteries. Auto manufacturers tend to provide different answers when it comes to the question of an alternator’s life expectancy.

On average, you can expect your car alternator to last between 5 and 8 years. But it really depends on how often you drive, what model year your vehicle is, and how many miles you put on your vehicle.

For most car owners, expect to get somewhere in the range of 60,000 to 150,000 miles on their alternator.

Newer cars, especially those known for their reliability such as Honda, Toyota, and Lexus will be on the higher end of that range while older vehicles or economy cars will be near the lower end.

Some car manufacturers may even claim their alternators last the lifetime of the vehicle. While possible, it’s not typical.

Look for Signs of a Failing Alternator

It can be tricky to know when your alternator is failing. The symptoms of a failing alternator are almost identical to the symptoms of a failing battery. That is because they are both important power sources for your vehicle.

You cannot have one working power source without the other. They both rely on each other to allow the vehicle to run properly. But it’s more likely your battery is going bad than your alternator. Symptoms of an alternator that’s on its way out include:

  • Dimming Headlights
  • Inability to Start Your Car
  • Alternator Warning Light is On
  • Electrical Components Stop Working
  • Strange Noise from the Engine Bay

Conclusion

Pay close attention to the mileage of your vehicle and the number of years you’ve had your battery and alternator. Using this information alone can usually help you figure out whether the alternator or battery has gone bad.

But be aware that if you replace your alternator at a repair shop you don’t know anything about. They may give you a refurbished alternator as a replacement while telling you it’s new.

Because of this, the used alternator will last about 2 to 4 years instead of 5 to 8 years. You’ll want to do your research when it comes to finding a shop to replace your alternator.

This is an often-asked question. Alternators are one of the few automotive parts that can be reused with reconditioning safely. Depending on your situation, there may be reasons to consider any of the three options. Here are a few things to know about the differences in a new, remanufactured and rebuilt alternator.

Rebuilt Will Cost Less

The reason you may be considering a rebuilt is the cost. You could save up to about half on a rebuilt alternator.  In this process the broken parts are replaced, hence the term rebuilt. You may get up to a 90-day warranty. Remanufactured alternators still offer some savings, around 25% generally, and are different than rebuilt ones. They tend to come with a one-year warranty and have been completely inspected and rebuilt. However, if you’re planning on keeping your car for a long time, it is worth the increased expense to purchase a new one.

Quality Varies

Although its true that quality varies on new products too, they vary more with rebuilt or remanufactured products. Depending on the product, only the visibly bad or worn parts may be replaced. Better quality ones have all the consumables replaced. You just don’t know until its in your car if its going to last for one day past its warranty or years past.  Also, keep in mind that the parts used in both rebuilt and remanufactured alternators are not always of the highest quality. Again, the warranty will give you an idea of the quality, but not always.

Trust Your Mechanic

If your mechanic won’t rebuild your alternator, there’s probably a good reason. If they give you pushback about a certain brand remanufactured one and steer you to another brand, they probably know both manufacturer’s reputations. Remember, their reputation is also on the line if they sell you something that fails quickly.

Although there is no one right answer for every situation, we rarely recommend a rebuilt alternator. Sometimes a remanufactured alternator is a good option, but most of the time we recommend a new alternator. If you’re having an issue with your starter, bring your car (or have it towed) to Oldsmar Automotive at 3166 Tampa Road and we’ll help you make the right decision.

However, we can say with near certainty that an alternator will not last for the average life of a vehicle. In general, you can expect alternators to last about 6-10 years, or about 80,000-150,000 miles.

How often do you need to replace an alternator?

The average longevity of an alternator is seven years or about 150,000 miles. Several factors can impact the lifespan of your alternator, including the quality of the part, the overall condition of the vehicle, and how many electronics are being used.
