As a car owner, you may take your vehicle for granted when you get up every morning. After all, with a simple push of a button or turn of a key, you can get anywhere you need in minutes. But while starting your car is easy, many components you may not think about are working behind the scenes to keep it running, including the alternator.

As a vital part of any vehicle, understanding how your car’s alternator works and whether or not your warranty covers it can help you stay one step ahead of unexpected and costly repairs.

What Is an Alternator?

An alternator is an electrical generator mounted on your car’s engine to convert mechanical energy to electrical energy. This alternating current is generated by the alternator pulley being rotated by the serpentine belt, which is driven by the crankshaft pulley.

As to locating your car’s alternator, most are usually found on the front of the engine, in line with your engine accessories. This allows your alternator to create the correct amount of electricity to keep your car battery charged and the electrical system running when the car is running, based on the specific engine speed or RPMs. However, you can simply check your owner’s manual to learn precisely where your car’s alternator is.

What Are the Signs of a Bad Alternator?

The alternator on any car is considered a “wear & tear” item, meaning it will need to be replaced over time. Specifically, the rotor and brushes can become worn due to use and exposure to elements, so you will most likely need to replace an alternator on an older car as time goes on.

However, while all alternators need to be replaced at some time, some can start to show signs sooner than others based on how quickly they wear. This makes recognizing the signs of a bad alternator important to help you save time and money by narrowing down your vehicle’s charging or starting issues. And without the proper knowledge, you can easily spend money replacing your battery or starter when your alternator was the actual problem.

Here are a few signs of a bad alternator you can look for:

• Battery Light Illuminates on Dashboard
• Dim/Flickering Headlights (Or Other Electronics)
• Dead Battery
• Strange Noises Coming from the Alternator
• Burning Smell Coming from the Alternator
• Electrical Accessories Have Slowed Down
• Difficulty Starting
• Car Stalls When Driving

Having your alternator replaced is a quick and easy job for most mechanics, though the part itself can be costly. For example, in a front-wheel drive vehicle, the alternator is mounted on either the engine’s right side or the lower section, like a Honda Civic. With that, you can expect to pay between $777 and $1,204 for an alternator replacement, according to the experts at RepairPal. However, the bulk of this cost is the new alternator itself, as the labor costs will only cost you around $203 to $299.

On V8 engines or rear-wheel drive vehicles, the alternator is usually easier to get to as it is mounted on the front of the engine. Still, the costs can be similar, as with the Chevrolet Silverado 1500, where you can expect to pay between $149 and $219 for labor, while the alternator will cost between $496 and $669, totaling anywhere from $645 to $888.

Will My Warranty Cover My Car’s Alternator?

If you’ve recently purchased a brand-new car, you’ll most likely have an active factory or manufacturer’s warranty, which will typically include coverage for your alternator. However, this won’t be a part of your factory coverage’s powertrain warranty, as the alternator is a component of your car’s electrical system.

Instead, you will most likely find this coverage as a part of the “new vehicle” limited warranty that comes with the car. But, while both types are helpful, factory warranties do not last forever, so you will need to get additional coverage once your factory warranty expires to protect your alternator.

For most automakers, you can look to purchase an “extended car warranty” to quite literally extend your coverage with them. However, you may only be able to purchase this extension when your original coverage is still active. If you wait too long or purchase a used vehicle past its factory warranty cutoff, you’ll be left without that extra peace of mind. Luckily, purchasing a vehicle service contract from third-party providers like us at Endurance can be just what you need.

While not offered by your automaker, vehicle service contracts (or VSCs for short) can provide factory-warranty-like coverage for your alternator and often include extra perks. For example, like your car’s factory warranty, a vehicle service contract from Endurance can protect your car’s alternator. But, unlike your factory coverage, which may keep you from only getting repairs done at the dealership, you can go to any local certified auto repair shop ASE-Certified mechanic. You’ll even be able to find other perks when using a third-party provider. These can include 24/7 roadside assistance, towing, trip interruption coverage, and rental car reimbursements—all of which come for free with every Endurance plan.
