Valeo Alternator 12V 120A Part No. 439312

Valeo alternator, 12V and 120A, part number 439312, supplied as a new rotating electrical unit for suitable euro vehicle applications. It is an alternator assembly rather than a repair kit, with an internal regulator and a 6 groove pulley arrangement to suit the listed configuration.

Key mounting details matter with this unit. The alternator is specified with a quad leg mount, 127mm centre to centre mounting, 60mm inside mounting legs, and a double pivot lever fastening type. The pivot hole diameter and adjusting hole diameter are both listed as M8x1.25 / 8.5, so those points should be checked carefully against the vehicle or removed unit before ordering.

Electrical and connection details are also important here. This Valeo alternator is rated at 120 amps, uses a 12 volt system, and is listed with no connector for revolution counter. The pulley outside diameter is 56mm and the position / degree is R 90, so matching the physical layout is just as important as matching the part number.

Application and Buying Notes

Before ordering, compare the part number 439312 with the number on your existing alternator and check the mounting layout against the 127mm centre to centre measurement, 60mm inside mounting legs, and quad leg mounting style. A close match on these physical points is essential because alternators can differ even within the same make and model range.

The pulley and electrical specification should also be confirmed. This unit is a 12V alternator with a 120A output, 6 groove pulley, internal regulator, and a 56mm pulley outside diameter. It is also listed with no connector for revolution counter, so the connector arrangement needs to match what the vehicle uses.

Fitment references include Audi, Seat, Skoda, and Volkswagen applications, but those names alone are not enough to confirm compatibility. Match the vehicle application, the part number, the mounting style, and the connector details together before purchase, especially if the vehicle has been modified or the previous alternator has already been replaced.

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 439312 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.
