Valeo 439546 Alternator

Valeo OE Alternator for Mercedes-Benz and Dodge

Valeo alternator 439546 is a 12-volt, 180-amp charging unit built for vehicles that need stable electrical output and OE-level fitment. It is a Valeo OE family alternator with an internal regulator, internal fan, clockwise rotation, and a 7-groove pulley for direct replacement service.

Valeo has supplied original equipment electrical systems since 1923, and this alternator reflects that OE-focused design approach. The 439546 part number is used across select Mercedes-Benz Sprinter, E-Class, ML-Class, R-Class, and Jeep Grand Cherokee applications, making it a strong match for drivers searching for a Mercedes-Benz Sprinter 2500 alternator or a Dodge Sprinter 3500 charging system replacement.

Key Features

• 12-volt alternator with 180-amp output
• Internal voltage regulator for simplified charging control
• Internal fan design
• Clockwise rotation
• 7-groove pulley configuration
• Aluminium housing for OE-style construction
• Valeo OE family replacement part
• Technical number: TG17C030B

Detailed Description

Valeo 439546 is engineered as a 100% new alternator, which removes the uncertainty associated with reused internal components. Its OE supplier background and application coverage make it a practical replacement for charging-system service on 2010-2018 Mercedes-Benz Sprinter 2500 and Sprinter 3500 models, as well as select 2007-2009 Dodge Sprinter 2500 and Sprinter 3500 vehicles. It also cross-references with select Mercedes-Benz E320, ML320, R320, R350, and Jeep Grand Cherokee applications. This part cross-references Bosch AL0843X for the same application.

For buyers comparing a Valeo alternator 439546 against other OE-style charging parts, the key specifications are the 12V system, 180 amp rating, internal regulator, and clockwise rotation. Those details matter when replacing a failing alternator on a Mercedes-Benz Sprinter 2500, Mercedes-Benz Sprinter 3500, or related diesel and gasoline applications that rely on consistent charging performance.

What It Helps Solve

• Battery warning lights caused by weak charging output
• Low-voltage conditions during idle or accessory use
• Charging instability from a worn alternator
• Electrical system strain in high-demand vehicle operation
• Starting issues related to insufficient alternator output

Installation Notes and Tips

Verify pulley groove count, rotation direction, amperage rating, and connector match before installation. Confirm vehicle application by year, make, and model, especially on Mercedes-Benz Sprinter and Dodge Sprinter platforms where OE supplier specifications are important. Inspect the belt, tensioner, and charging connections during replacement to help avoid repeat charging faults.

Quality Assurance

Valeo is a long-standing OE supplier in electrical systems, and this alternator is built as a new replacement unit rather than a remanufactured assembly. That OE-oriented construction supports consistent fitment and charging performance across the listed applications.
