Genuine Mercedes-Benz Alternators

Your Mercedes-Benz vehicle's alternator is one of the three primary parts of its charging system. It charges the battery in your car or SUV and powers its many electrical systems. It turns mechanical energy into electrical energy. This makes the vehicle's instrumentation light up and everything from the power windows and windshield wipers to the steering system and electronics run.

What Causes Alternator Failures?

What causes alternator failure can be an overtightened belt, installing the wrong accessories, jump-starting your vehicle improperly, or just plain degraded parts. That failure may happen with a warning, too. Here are some symptoms that show up:

• The car lighting behaving erratically
• Warning lights for the battery and alternator lighting up on the dashboard
• A squeaking engine
• Alternator fluid leaking
• The smell of something burning under the hood

In such cases, an inspection is strongly recommended. You should follow it up immediately with a test of your vehicle's charging system, too. Be sure to replace any parts that any of the results recommend.

What is the Maintenance for an Alternator?

When should you change an alternator, though? Every 80,000 miles or every 7 years -- whichever comes first. Don't put off the job any longer than 150,000 miles, though. As for how to install a new one, generally, all you need to do is disconnect the battery and detach some wires, move a tensioner pulley, take off a few bolts, and remove the old alternator. Review your owner's documentation or the manufacturer's instructions for more specific info. Before ordering one to put in, though, be sure it's genuine.
