The many accessories that are included in most high-end vehicles require a good amount of power to function, all of it provided by the Mercedes alternator. The power seats and windows, air conditioning and stereo system draw a lot of power. The alarm system and the keyless entry take power as well. That remote car starter needs power, as well as the more essential systems, like the ignition coils. All that power that is so necessary to the Mercedes driving experience depends upon the relatively simple Mercedes alternator. The battery in your vehicle needs to be fully charged at all times to provide the power to run your electrical system. The alternator provides that charge, working to produce the necessary power at all times when the vehicle is running. The power producing process uses the mechanical energy of the engine crankshaft, transmitted by a serpentine belt to turn the Mercedes alternator, which then is able to use that motion to produce electrical energy, or voltage. This voltage is then used by the battery to stay fully charged, and provide the many vehicle systems with power. If the Mercedes alternator begins to wear, you may notice that some of your accessories are not functioning as well, perhaps your dash lights or headlights will dim, or your windshield wipers will move more slowly than usual. If you have a Mercedes alternator that is showing signs of wear, we have a selection of quality replacements available in our online catalog at great low prices. Our user-friendly secure site is will be quick and efficient in taking your Mercedes alternator order, or our toll-free phone line is available for your convenience
Mercedes-Benz Alternator Buyer's Guide
- The immense power needed to run a Mercedes-Benz vehicle’s high-end systems comes from the alternator.
- Made by the same manufacturer that designed and built the car or a partner company, Original Equipment Manufacturer (OEM) parts serve as exact replacements for damaged or worn stock parts.
- Produced by other companies unrelated to a vehicle’s manufacturer, Original Equipment (OE) parts offer more choices and options at a lower price while delivering the same level of performance as OEM parts.
- Remanufactured alternators
- An alternator can cost anywhere between $50 and $731. The price tag varies according to its brand or manufacturer and whether the part is new or remanufactured.
Mercedes-Benz vehicles come with the finest accessories created by German engineering. are Advanced features like keyless entry and remote car start-up exist alongside typical offerings like air conditioning, power seats, and power windows.
The power for running these high-end systems comes from the alternator. With the help of a serpentine belt connected to the engine crankshaft, the alternator generates electricity that charges the battery and supplies the Mercedes-Benz’s power needs.
Eventually, the Mercedes-Benz alternator will wear out or even break from the rigors of everyday use. This brief guide can help you find the best option for your Mercedes-Benz.
OEM car alternator versus OE alternator
Like with any other car parts, you can divide alternators between OEM and OE parts. Knowing the difference can help you save time and money.
The stock alternator found in any Mercedes-Benz vehicle is an Original Equipment Manufacturer (OEM) part. Made by the same manufacturer that designed and built the car or a partner company, OEM parts serve as exact replacements for damaged or worn car parts.
Also called Genuine parts, OEM parts exclusively appear at official dealerships and affiliated car parts stores. Mercedes-Benz runs an auto manufacturing plant near Vance, Alabama, but replacement parts may still come from abroad.
Produced by other companies unrelated to a vehicle’s manufacturer, Original Equipment (OE) parts offer additional options for replacing old or broken parts. OE parts deliver the same level of performance as OEM parts at a lower price. They also enjoy wider availability, being found on the shelves of most car parts stores.
Comparing new alternators and remanufactured alternators
Not all replacement alternators at the car parts supplier come fresh from the factory. Many products are old units that underwent a remanufacturing process to make them as good as new.
These alternators get disassembled into individual parts for scrutiny. New versions replace parts prone to wearing out or breaking down.
The remanufacturer may even replace an obsolete part with a modern design. When upgraded this way, an alternator can match the performance of its successor.
Telling apart remanufactured, rebuilt, and repaired alternators
Remanufactured alternators also differ from rebuilt or repaired counterparts.
Repaired alternators broke down or wore out at some point. Replacing their damaged parts restores most of their performance.
Rebuilt alternators are old but functional parts. The rebuilding process disassembles them for examination. If an electrical or electronic part fails the test, it gets replaced with a new one. A component known to wear out quickly may also get changed without a test.
Finally, remanufactured alternators remove all parts with short lifespans and replace them with new or modern parts.
Renowned parts manufacturers like ACDelco offer remanufactured alternators alongside new-built parts. These companies run the remanufactured parts through stringent tests to make sure the alternators measure up to their standards.
If you go for a remanufactured alternator, look for one made by a Factory Authorized Remanufacturer. These items received the approval of the original parts maker and can match the performance of the OEM part.
How much does a Mercedes-Benz alternator cost?
An alternator can cost anywhere between $50 and $731. The price tag varies according to its brand or manufacturer and whether the part is new or remanufactured.
