Valeo Alternator 12V 75A 439287 - Internal Regulator, 6 Groove Pulley

The Valeo Alternator 12V 75A, part number 439287, is a new rotating electrical unit supplied as each and rated at 75 amps on a 12V system. It has an internal regulator, a 6 groove pulley, and a listed weight of 6.52kg, which are all useful checks when matching the replacement to the vehicle and the original unit.

This alternator is listed with a twin leg alternator mount, double pivot lever fastening type, 67mm inside mounting legs, and 169mm mount centre to centre. Those mounting measurements matter when comparing brackets, spacing, and the way the alternator sits in the engine bay.

The connector is listed as with revcounter coupling, and the pulley outside diameter is 55mm. The product is identified as Valeo brand, with product group 1 as rotating electrical and product group 2 as alternators, so it is clearly positioned as a replacement alternator rather than a universal accessory.

Application and Buying Notes

Before ordering, compare the part number 439287, the 12V rating, and the 75A output against the unit already fitted to the vehicle. The important mounting checks here are the 67mm inside mounting legs, 169mm mount centre to centre, 10mm adjusting hole diameter, and 10mm pivot hole diameter, as these dimensions need to match the application closely.

The pulley setup also needs attention. This alternator uses a 6 groove pulley with a 55mm outside diameter, so it should be checked against the belt arrangement on the vehicle rather than assumed to suit by appearance alone. The connector is listed with revcounter coupling, which is another useful identification point when comparing plugs and ancillary connections.

A one year warranty is listed, and the unit is new rather than remanufactured. That said, alternator replacement still depends on matching the physical mount, pulley section, regulator type, and connector arrangement to the vehicle. For the clearest result, confirm the original alternator markings and compare them with the listed details before purchase.

The only explicit vehicle application supplied here is Renault 19 with F3P engine. There is additional Renault Laguna fitment information present in the fitment data, but it is not supported by the product facts provided, so it should not be treated as confirmed fitment without checking the part number and the vehicle’s charging system details first.

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 439287 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 439287, 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 75 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
