Valeo Alternator 12V 180A 439751

This Valeo alternator is a new 12V unit with a 180A charge current and part number 439751. It is listed as a Valeo unit with internal regulator, twin leg alternator mount and four-point mounting, so the physical mounting arrangement and electrical specification both need to line up with the vehicle application before purchase.

Key dimensions include 61mm inside mounting legs, 8mm pivot hole diameter, 8mm adjusting hole diameter and a 49mm pulley outside diameter. The pulley is 6 groove, and the unit is marked R 90 position / degree with no connector for revolution counter.

Valeo is identified here as a leading OE manufacturer and supplier for many euro vehicles. That makes the unit relevant where an OE-style replacement is needed, but it still needs to be matched on part number, mounting style, pulley configuration and output rating rather than on brand name alone.

Application and Buying Notes

Before ordering, compare the part number 439751 with the alternator already fitted to the vehicle, then check the mounting style and pulley details. This unit is a twin leg alternator with four-point mounting, 61mm inside mounting legs, 8mm pivot hole diameter, 8mm adjusting hole diameter and a 49mm pulley outside diameter, so those details need to align with the existing unit.

The electrical setup also matters. This alternator is a 12V unit with 180A output and an internal regulator. If the vehicle uses a different voltage, a different charge current, or a different regulator arrangement, the correct replacement may be different even where the vehicle family looks similar.

The pulley is listed as 6 groove and the connector note states no connector for revolution counter. That means belt type, pulley groove count and connector arrangement should be checked during comparison with the original part. Small differences in these areas can stop the alternator from fitting or functioning as intended.

The application groups provided include Skoda Superb and several Volkswagen models, but the fit still depends on the exact vehicle setup and the alternator fitted from factory. Use the vehicle details together with the part number, mounting measurements and pulley specification before you commit to the order.

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 439751 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.
