Valeo Alternator 12V 120A 439471

The Valeo Alternator 12V 120A, part number 439471, is a new rotating electrical unit with a 12 volt system and 120 amp charge current. It is listed as a direct mount alternator with direct fastening, which makes the mounting style and application check an important part of the buying process.

This unit uses a 7 groove pulley with a 57mm pulley outside diameter, an internal regulator, and a connector arrangement noted as no connector for revolution counter. Those details matter because alternator fitment is often determined by pulley, mounting, regulator, and plug style as much as by the vehicle model.

Valeo identifies this alternator as suitable for Mercedes-Benz applications, including C-Class, CLC-Class, CLK, E-Class and SLK listings within the fitment data supplied. The part weighs 7.07kg and is sold each, with a one year warranty.

Application and Buying Notes

Before ordering, check the alternator part number 439471 against the unit you are replacing, then compare the mounting style, pulley section, and regulator type. This alternator is a direct mount design with direct fastening, a 7 groove pulley, and an internal regulator, so those physical details need to match the vehicle already fitted.

The electrical rating is 12V and 120A, which is the key output figure to confirm against the vehicle requirement. The connector note also matters: this unit is listed with no connector for revolution counter, so the plug arrangement must be checked carefully before purchase.

The supplied fitment data shows Mercedes-Benz applications across C-Class, CLC-Class, CLK, E-Class and SLK listings. Even where the model family matches, variations within the same range can use different charging system configurations, so the safest check is to match the part number, pulley details, and connector arrangement together.

If you are replacing a failed alternator, compare the old unit’s pulley outside diameter, groove count, and mounting points before fitting the new one. A 57mm pulley and 7 groove belt profile are specific details that should be verified, especially where the vehicle has been previously repaired or modified.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 439471 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number 439471, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number 439471, the 12V 120A output, 7 groove pulley, 57mm pulley outside diameter, direct mount/direct fastening arrangement, and the listed connector setup against the vehicle currently fitted.
