OEM VW Alternators

Car Alternators at a Glance

Without a working alternator, no Volkswagen car or SUV could run at all. Worse yet, one can fail without warning. Let our auto parts store help you avoid that catastrophe by telling you what you need to know about them, so that, when it comes time to replace yours, you can make an informed buying decision.

What is an Alternator?

It's the main part of the charging system in your VW vehicle.

What Do Alternators Do?

They turn mechanical energy into electrical energy -- in other words, they generate AC current and convert it to DC current managed by a voltage regulator. Even simpler, they turn energy created by moving parts into electricity your vehicle can use to run its systems.

How Does an Alternator Work?

The engine in your Volkswagen uses serpentine and drive belts to move a pulley and turn a rotor shaft and some coils. This creates a magnetic field whose power a rectifier captures. Your vehicle uses that power to charge its battery and run things like the radio, the dash lights and digital displays, your power windows and steering, your windshield wipers, and more -- even options such as heated seats.

What are the Causes of Alternator Failure?

Usually, one of four things: installing incompatible accessories, jump-starting wrong, an overly tight alternator belt, and/or worn or damaged alternator parts.

What are the Signs an Alternator is Going Bad?

  • Lit alternator and battery warnings
  • Issues with your lighting, car electronics, and other electrical systems
  • A dead battery
  • A burning smell under the hood, near the battery or alternator
  • Alternator fluid leaking
  • A squealing engine

When to Replace an Alternator

Figuring that out depends on the results of a thorough inspection and charging system test. Otherwise, it's a good idea to change an alternator every 7 years. That's about every 80,000 to 150,000 miles.
