Valeo Alternator 12V 120A 439263

This Valeo alternator is a new 12V unit rated at 120A, supplied under part number 439263. It is listed with a 5 groove pulley, clockwise rotation, internal regulator, and a quad leg alternator mount, so those details should be checked carefully against the unit being replaced.

The alternator is identified as a Valeo product for the Valeo unit make, with pin code IR139 and a connector description of no connector for revolution counter. It also uses a 57mm pulley outside diameter and double pivot lever fastening type, which are practical identifiers when matching a replacement alternator.

Valeo is noted here as a leading OE manufacturer and supplier for many euro vehicles. Even so, alternator fitment should always be confirmed by part number and application details, because mounting style, pulley configuration, rotation, and connector arrangement can vary between similar-looking units.

Application and Buying Notes

Before ordering, compare the removed alternator against the key identifiers here: part number 439263, 12V voltage, 120A output, 5 groove pulley, clockwise rotation, and quad leg mounting. These are the most useful checks for avoiding a mismatch when the vehicle details are not enough on their own.

The pulley details matter as much as the electrical rating. This unit has a 57mm pulley outside diameter and a 5 groove belt arrangement, so the belt layout on the vehicle needs to match. If the pulley section or rotation direction differs, the alternator may not be suitable even if the connector appears similar.

Connector layout is another point to verify. This alternator is described as having no connector for revolution counter, so it is important to compare the plug and charge system arrangement on the vehicle before purchase. The internal regulator also means the charging control design should be checked against the original unit.

The weight is listed at 6.45kg, which can be a useful sanity check when comparing to a removed part. As with any charging system component, confirm the mount style, fastening type, and physical shape against the original alternator rather than relying on appearance alone.

This part is supplied as a new unit and carries a one year warranty. That gives a clear replacement option for vehicles that use the same Valeo configuration, but the safest approach is still to confirm the part number 439263 and the application details on the existing alternator or vehicle records before fitting.

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 439263 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.
