Subaru Alternators

SubaruOnlineParts provide original equipment manufacturer (OEM) alternators for your Subaru vehicles. This component maintains the performance of your car’s battery by using the engine’s power to charge the battery cell. We offer genuine alternators for various Subaru models, ranging from the oldest Justy to the latest WRX.

Improve Your Car Battery’s Performance with a Subaru OEM Alternator

An alternator’s main parts include a rotor, stator, diode rectifier, and voltage regulator. The rotor acts as the rotating component of this equipment. It has magnets that generate an alternating current (AC) to charge your car’s battery. Meanwhile, the stator is the stationary part of an alternator. The stator’s coils send the AC to a set of diode rectifiers. These connected diodes are then responsible for regulating the current. Together, these components ensure that your battery has sufficient load for every car ride.

It is essential to inspect this component regularly since a malfunctioning one gives various problems. For instance, a weak alternator causes a weak or dead battery. As a result, you will have a difficult time starting your Subaru vehicle. Odd noises from your car’s hood is also a sign of a bad alternator. Thus, it is crucial to incorporate a compatible unit to your vehicle.

Frequently Asked Questions About Subaru Alternators

What is an alternator in a car?

Car alternators power the different electrical components of your car. The alternator has a rotor shaft that spins a set of magnets around a coil, generating the alternating current (AC). This gets converted into a direct current (DC) to power and activates the electrical systems of your ride.

How long does a car alternator last?

Typically, alternators for cars can last up to seven years or between 80,000 to 150,000 miles. Other factors like the quality of the alternator, power drain, and driving conditions can cause your alternator to deteriorate faster. Proper maintenance of this component and its different parts, such as the bearings and connectors, is needed to extend its longevity.

Can you jumpstart a car with a bad alternator?

In some instances, drivers can jumpstart their cars with a faulty alternator as long as the car battery has enough charge to run the vehicle. We recommend changing your broken or faulty alternator as soon as possible, as driving with them can be extremely dangerous. If you can’t start your car reliably, it can indicate a broken alternator.

How to test a car alternator?

You can see if your alternator is still working by checking the voltage of your battery using a multimeter. The volt range of your battery should be somewhere between 12 to 13 with the engine off. Once you take the initial reading, you should check your battery while the car is running and see if it is at 13 to 14 volts.

How to replace a car alternator?

You must first loosen and remove the serpentine belt when repairing your alternator. Set it aside and start clearing all the corresponding parts of your alternator. You can then line up the bolt holes and tighten the bolts according to the correct tension. You can also replace the belt with a new one if needed, and make sure you adjust to the proper belt tension accordingly.
