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.

At SubaruOnlineParts, we provide customers with 100% genuine alternators and related auto components.
