Valeo Alternator 12V 180A New 439762

The Valeo 12V 180A alternator, part number 439762, is a new rotating electrical unit supplied as an each item. It is specified with a 180 amp power rating, internal regulator, and a 6 groove pulley, making the key identification points easy to match before ordering.

This unit is listed with a quad leg alternator mount and four-point mounting, so the physical mounting style is just as important as the electrical rating. The pulley outside diameter is 51mm, and the alternator is noted as L 55 position / degree, which should be checked against the original unit on the vehicle.

Valeo is described as a leading OE manufacturer and supplier for many euro vehicles. For buyers comparing replacement options, the most useful identifiers here are the 12 volt system, 180 amp output, part number 439762, and the IR201 pin code.

Application and Buying Notes

Before ordering, confirm the part number 439762 matches the alternator being removed, then compare the 12V system, 180A output, and the 6 groove pulley. The mounting style is also critical here because this unit uses a quad leg alternator mount with four-point mounting, which needs to align with the vehicle’s bracket and original hardware.

The pulley outside diameter is 51mm, and the unit is marked L 55 position / degree. Those details can matter when checking belt alignment and physical clearance, so it is worth comparing them directly against the existing alternator rather than relying on appearance alone.

This Valeo alternator is a new unit with an internal regulator and no connector for revolution counter. If the original vehicle setup uses a different plug arrangement or external regulation, the replacement may not suit without the correct application match. Checking the IR201 pin code and the exact vehicle application is the safest way to proceed.

Weight is listed at 7.55kg, which can help when handling the part and confirming you are comparing the same style of unit. Where vehicles are listed in fitment data, model names such as Mercedes-Benz CLS, E-Class, G-Class, GL-Class, GLE, GLS, M-Class and SL appear in the application group, but the final check should still be made against the vehicle’s original alternator and part number.

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 439762 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 439762, 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 CLS, MERCEDES-BENZ CLS 2011, MERCEDES-BENZ CLS 2012, MERCEDES-BENZ CLS 2013. 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 compatibility by matching the part number 439762, the 12V / 180A specification, the 6 groove pulley, and the quad leg four-point mounting arrangement to the original alternator and vehicle application before purchase.
