Valeo Alternator 12V 180A 439712

Valeo Alternator 12V 180A, part no. 439712, is a new rotating electrical unit supplied as each. It is rated at 180A and uses a 12V system, with an internal regulator for applications that call for that configuration.

This alternator features a 6 groove pulley with a 51mm outside diameter, a quad leg mount, and four-point mounting. It weighs 7.59kg, so it is a substantial unit and should be matched carefully to the vehicle’s original mounting layout and electrical requirements.

The unit is listed with pin code IR201 and is supplied with no connector for revolution counter. It is identified as a Valeo alternator and is described as suitable for Valeo applications, with a one year warranty.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles. That makes the 439712 reference important when you are replacing an alternator on a vehicle where the original unit must match the exact mount, pulley, and charge current specification.

Application and Buying Notes

When replacing an alternator, the most important checks are the part number 439712, the 12V system voltage, and the 180A charge current. Those details need to line up with the vehicle’s original charging system so the replacement unit is a proper match rather than just a similar-looking part.

The mounting arrangement matters as much as the electrical specification. This unit is a quad leg alternator with four-point mounting, so the bracket pattern and physical installation points need to suit the vehicle. The 6 groove pulley and 51mm outside diameter also need to match the belt drive arrangement already on the vehicle.

This alternator is a new Valeo unit with an internal regulator and a weight of 7.59kg. That weight can be a useful cross-check when comparing against the original part, especially where the physical form, connector arrangement, or pulley style needs to be matched exactly.

The supplied fitment information points to Mercedes-Benz applications, including E-Class and SLS AMG ranges in specific model years. Even where the model name appears in the fitment data, the safest approach is still to confirm the existing alternator against the vehicle identification details and the original unit before ordering.

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 439712 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. 439712, Brand VALEO, Description Valeo Alternator 12V 180A, Pin Code IR201, Pulley Outside Diameter 51mm, Regulator Type Internal, Voltage 12, New / Reman. New, Position / Degree L 60.

Valeo Alternator 12V 180A. Part number 439712 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. 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 439712, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ E-CLASS, MERCEDES-BENZ E-CLASS 2009, MERCEDES-BENZ E-CLASS 2010, MERCEDES-BENZ E-CLASS 2011. 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: Confirm fitment by checking part number 439712, 12V system voltage, 180A output, quad leg four-point mounting, 6 groove pulley, 51mm pulley outside diameter, and the vehicle application details before purchase.
