OEM Acura Alternators

Refine Results

The alternator is a primary part of the charging system in an Acura vehicle. Without it, that luxury car or SUV you love to drive wouldn't run at all. Looking to learn more about it? You've come to the right auto parts store.

All About Acura Alternators

What One Does

Put simply it turns mechanical energy into electrical energy. In doing so, it charges the car battery and helps run electrical systems like the dash lights and displays, power windows, car radio, power steering, windshield wipers, and more.

How One Works

The process starts with the engine. It runs serpentine and drive belts. The belts move a pulley, which turns a rotor shaft, which spins a set of magnetic coils. The collective movement creates a magnetic field -- in other words, electricity, AC current that a rectifier transforms into DC current, which a voltage regulator manages.

Why They Fail

There are generally four causes: damaged or degraded alternator parts, an overtightened belt, a bad jump-start, or an improper accessory install. Failure usually happens with no warning. Luckily, there are symptoms that suggest one is going out.

The Signs of a Bad One

They include:

  • Warning lights on the dashboard -- battery and/or alternator
  • Lighting problems
  • Electronics malfunctions
  • Leaking alternator fluid
  • Engine squeaks
  • A dead battery
  • A burning smell under the hood, usually near the battery or alternator

If you see any of them, inspect the alternator and test the charging system overall. Change the alternator if the results call for it.

When to Replace One Otherwise

Take care of it every 7 years or every 80,000 to 150,000 miles, whichever comes first. For more information on what to do, take a look at the maintenance schedule in your owner's manual. And if you're looking to buy a new one, you can do it online, right here; it'll come straight from Acura.
