Valeo Alternator 12V 150A 439679

The Valeo 12V 150A alternator, part number 439679, is a new rotating electrical unit with a 12-volt output and a 150 amp charge current rating. It uses an internal regulator, a 6 groove pulley section, and a 50mm pulley outside diameter, which are the key details to match against the existing unit before purchase.

This alternator is supplied as each unit and weighs 6.87kg. It uses a pad alternator mount with four-point mounting and a mount leg thickness of 70mm. The connector detail is listed as no connector for revolution counter, so the plug and charge control arrangement should be checked carefully against the vehicle and the removed unit.

Valeo is listed as the brand and suits Valeo unit make applications. The product is described as a Valeo Alternator 12V 150A, and the supplied compatibility information shows Mercedes-Benz applications across C-Class, CLK, E-Class, SLK, Sprinter 3-T, Sprinter 5-T, and 5-T variants in the listed year ranges. Confirming the part number and the physical mounting details is essential before fitting.

Application and Buying Notes

Before ordering, compare the listed part number 439679 with the alternator already fitted to the vehicle. The key hardware details here are the 12V rating, 150A output, pad mount, four-point mounting, 70mm mount leg thickness, and 50mm pulley outside diameter. If any of those do not line up with the removed unit, the alternator may not be the correct match even if the vehicle model is similar.

The pulley section is 6 groove, and the regulator is internal. Those details matter because alternators can differ by belt arrangement and charging control even within the same model range. The connector detail is also specific: no connector for revolution counter. If the vehicle or the original unit uses a different connector arrangement, that needs to be checked before fitting.

The supplied fitment information includes Mercedes-Benz C-Class, CLK, E-Class, SLK, Sprinter 3-T, Sprinter 5-T, and 5-T applications across the listed years, but model badges alone are not enough to confirm compatibility. Matching the application with the part number, pulley style, mount style, and connector arrangement is the safest way to avoid an incorrect purchase.

As with any charging system component, it is also worth checking the condition of the belt, terminals, and related charging circuit before installation. A new alternator can only perform as intended when the surrounding components are in suitable condition and the vehicle’s original specification is correctly matched.

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 439679 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.

Valeo Alternator 12V 150A. Part number 439679 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439679, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 2002. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using part number 439679 and the physical details above, including 12V, 150A, 6 groove pulley, internal regulator, pad mount, four-point mounting, 70mm mount leg thickness, and the no-connector revolution counter arrangement. Model name alone is not sufficient to confirm compatibility.
