OEM Acura Alternators

Refine Results

Alternators distribute battery power across a vehicle's electrical system via a network of wiring, fuses, and relays. In short, a battery's job is to start, but an alternator's job is to keep everything running.

When Should you Replace Your Alternator

It can be difficult to tell. Alternator failure can happen with little warning. Luckily, though, there are signs your alternator is going bad, well beyond a warning light turning on. One is flickering headlights, if not trouble with other lighting. Another is your entertainment system working erratically. Your battery or alternator can smell burned, or your engine might start squealing. You could even cause your alternator to go out yourself by jump-starting your Acura incorrectly or overloading it during an incompatible accessory install. The result: total electrical failure.

Sometimes, the symptoms of a faulty alternator are entirely absent. Finding a dead battery is a good example. It can mean that your alternator has switched your electronics to battery power. Do an inspection and a charging system test to be sure of the problem. Replace your alternator if necessary. Otherwise, it's a good idea to change an alternator every 7 years. That's about every 80,000 to 150,000 miles. Consult your owner's manual for details. It should have a maintenance schedule you can review.

Genuine Acura Alternators Work Best

When it's time to get a new alternator, be sure to buy genuine. The best alternator for your Acura is, after all, made by your OEM. Order yours online from our auto parts counter now. We'll ship immediately, right to your door.
