Factory Subaru Alternators

A well-maintained charging system helps keep every drive smooth, whether you're heading across town or hitting the highway. That starts with a reliable alternator. It supplies power to your vehicle’s electrical system and keeps the battery from draining. At Conley Subaru Parts, we carry the exact parts designed to match Subaru's engineering standards.

What the alternator handles under the hood

The alternator converts mechanical energy into electricity to keep your vehicle’s battery charged and support everything from headlights to fuel injection. In Subaru models like the Ascent and Impreza, the alternator works continuously while the engine runs. A dependable alternator helps ensure your vehicle starts reliably and electronics operate without issue. When it’s working properly, you likely don’t even think about it.

What causes alternators to fail

Over time, alternator bearings can wear down, internal parts may overheat, and voltage regulators can stop working. Warning signs include dimming lights, slow starts, or battery warning lights on your dash. Most alternators need to be replaced around 100,000 miles, but heavy use or extreme weather can shorten that timeline. Regular checks during service appointments can help you catch issues early.

Why choosing genuine Subaru parts matters

Only genuine Subaru alternators are designed for the specific power requirements of your model. Generic aftermarket brands often use lower-quality materials and may not deliver the same consistent output. We offer only OEM Subaru parts that maintain your vehicle’s performance and reliability. While replacing your alternator, consider installing a new battery to keep your electrical system fully supported.
