Valeo Alternator 12V 90A 439311

The Valeo Alternator 12V 90A, part number 439311, is a new alternator supplied as each unit. It is rated at 90 amps and 12 volts, with a 6 groove pulley, clockwise rotation, and an internal regulator.

This unit suits Valeo applications and uses a quad leg alternator mount with four-point mounting. The pulley outside diameter is 57 mm, and the connector note specifies no connector for revolution counter. Weight is listed at 5.54 kg.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles. That makes correct identification important, especially where the alternator mount, pulley style, rotation, connector arrangement, and part number all need to match the vehicle’s original unit.

A one year warranty is listed. If you are replacing an existing alternator, the safest approach is to compare the part number 439311, the mounting style, and the electrical details before ordering.

Application and Buying Notes

When replacing an alternator, the part number 439311 is the most reliable starting point, followed by the physical details: 12V system voltage, 90A output, 6 groove pulley, clockwise rotation, and internal regulator. If any of those differ from the unit already fitted to the vehicle, stop and compare carefully before ordering.

The mounting arrangement matters just as much as the electrical rating. This alternator uses a quad leg mount with four-point mounting, and the connector note states no connector for revolution counter. Those details can affect whether the unit physically installs and connects correctly, even when the vehicle family appears in the fitment list.

The fitment data references multiple euro vehicle groups, including Audi, Seat, Skoda and Volkswagen. That is useful for narrowing the search, but it is not enough on its own to confirm a match. Check the removed alternator, the belt pulley style, and the mounting points before assuming compatibility.

The listed pulley outside diameter is 57 mm and the weight is 5.54 kg. Those figures can help with comparison when identifying the correct replacement from a vehicle or workshop sample, particularly if the vehicle has had prior repairs or a non-original alternator fitted.

A one year warranty is listed for this new Valeo unit. Warranty coverage does not remove the need to confirm application details, so it is still best practice to verify the part number, regulator type, and mounting pattern before purchase and before installation.

If you are unsure, compare the old alternator to the photos and specification details rather than relying on the vehicle badge alone. A correct match depends on the full combination of voltage, amperage, pulley section, rotation, mount type, and connector arrangement.

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 439311 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.
