The Valeo alternator listed here is a new 12V unit with a 180A charge current and part number 439737. It is a pad-mount alternator with direct fastening, a 6 groove pulley, and an internal regulator, which are the key details to compare before ordering.

Valeo is identified here as the brand and suit unit make, and the alternator sits in the rotating electrical product group. The unit weighs 7.405kg and is supplied as each, so it is a substantial electrical component rather than a small service item.

This alternator carries a one year warranty and is described as a Valeo alternator 12V 180A. The connector detail is listed as no connector for revolution counter, so the wiring and instrument requirements should be checked carefully against the vehicle application and the removed unit.

Application and Buying Notes

Before ordering, match the part number 439737, the 12V system requirement, and the 180A charge rating against the original alternator fitted to the vehicle. The pulley details also matter: this unit uses a 57mm pulley with a 6 groove section, so belt configuration must align with the application.

The mounting style is pad mount with direct fastening, which means the physical mounting points and bracket arrangement need to match. The unit is listed with an internal regulator, so the vehicle’s charging system setup should be checked against that configuration rather than assuming all Valeo alternators are interchangeable.

The connector detail is important as well. This alternator is listed as having no connector for revolution counter, so the vehicle side plug and any rev counter related requirements should be confirmed from the existing unit or the vehicle’s electrical specification before purchase.

Weight can also be a useful comparison point during identification. At 7.405kg, this is a full alternator assembly, so comparing the old unit’s layout, pulley, mount, and connector arrangement is the safest way to avoid ordering the wrong part. If there is any doubt, use the removed alternator and vehicle application details together rather than relying on appearance alone.

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 439737 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.
