OEM Subaru Alternators

Refine Results
Your battery might start your Subaru, but another auto part charges it in the first place: your factory alternator. As part of your vehicle's charging system, it runs the many different electrical systems under your hood. It doesn't just light up your dash display and headlights, either. It makes your power steering work. It rolls your power windows up and down. It runs your windshield wipers and keeps your car radio playing. It's even what warms your heated seats if you have them. How do alternators work, though? It all starts with your engine. It uses a drive belt to run a pulley, and that pulley spins a rotor shaft. That shaft turns a set of magnetic coils. The movement generates alternating current (AC power) that a rectifier captures and turns into direct current (DC power). Your vehicle then starts and stays running. In short, alternators turn mechanical energy into electrical energy. Unfortunately, though, even those that Subaru makes can go bad eventually. It usually happens without warning, too. The causes of a bad alternator can be anything from age to broken-down parts and bad jump-starts. You can even cause alternator failure yourself by installing incompatible accessories. Luckily, you can spot symptoms of alternator problems easily. They include headlight flicker, car radio malfunctions, burning smells, engine whines, a dead battery, and even complete electrical system shutdown. If you think your Subaru has alternator problems, inspect it, and test your charging system. When do you replace an alternator otherwise? About every 80,000 to 150,000 miles. That's roughly every 7 years but double-check your owner's manual for a maintenance schedule to be sure. A genuine Subaru alternator will fit your model best. Our auto parts store can ship one to you immediately. Order it online today!
