Application and compatibility

The offered alternator belongs to the Alternators and generators category and is designed for selected Mercedes C-Class, CLK, E-Class, and S-Class models of the W203, C209, W211, and W220 generations with the Diesel OM648 engine. The design, tailored to specific power units, allows for maintaining the correct charging voltage, proper accessory belt routing, and seamless integration with the vehicle's factory electronics.

Thanks to its high current output, the alternator performs well in cars equipped with numerous energy consumers – extensive multimedia systems, heated seats, advanced comfort control modules, or safety systems. This solution is aimed at users who expect a stable electrical system during daily operation and on long journeys.

Operating parameters and technical characteristics

The 200A output alternator provides sufficient power reserve for the electrical system, reducing the risk of voltage drops under heavy load. Compatibility with the Diesel OM648 engine means that the charging characteristics are adapted to the unit's specifics – higher torque, different idle speeds, and typical accessory loads.

The design solution provided for this series of engines allows for:

• correct drive belt routing and proper system tension,
• stable battery charging across a wide RPM range,
• proper cooperation with the factory regulator and vehicle control units.

The alternator has dedicated part numbers and interchangeable numbers, which facilitates verification of compatibility with a specific car configuration and minimizes the risk of selecting the wrong component.

Product condition and benefits of installation

The offered alternator is used, which is an attractive solution for users looking for a technically sound component at a reasonable price. Choosing an original alternator from dismantling allows you to maintain factory fitment for mounts, electrical harnesses, and charging system operating parameters, without the need for modifications or adaptations.

The main advantages of installing this model include:

• maintaining compatibility with the factory Mercedes electrical system,
• adequate current output for well-equipped versions,
• the ability to restore proper battery charging after a failure of the previous alternator.

For proper selection, it is recommended to compare the part number and interchangeable numbers with the information in the vehicle's technical specification or with the data on the old alternator.
