Valeo Alternator 12V 120A 439339

This Valeo alternator is a new 12V, 120A unit with part number 439339, supplied as an each item and intended for rotating electrical applications where the existing unit matches the listed mounting and electrical details. It features an internal regulator, a 6 groove pulley, and a twin leg alternator mount, so it is important to compare the physical configuration before ordering.

The main dimensions provided are an inside mounting legs measurement of 67mm, a mount centre to centre measurement of 178mm, a pivot hole diameter of M10x1.5 / 10, and an adjusting hole diameter of 8mm. Those measurements are the practical checkpoints that help confirm whether the alternator will physically line up in the vehicle.

This unit is listed as a Valeo alternator with a 120 amp charge current and no connector for revolution counter. The application data supplied includes Fiat Ducato references, so buyers should verify the part number, pulley layout, and mounting measurements against the existing alternator before fitting.

Application and Buying Notes

When replacing an alternator, the safest approach is to match the part number 439339 first, then confirm the physical fit points: 67mm inside mounting legs, 178mm mount centre to centre, M10x1.5 / 10 pivot hole diameter, and 8mm adjusting hole diameter. Those details matter just as much as the 12V, 120A electrical rating because a unit can have the correct output but still not align correctly in the engine bay.

The pulley specification is also important here. This Valeo alternator uses a 60mm pulley with a 6 groove belt layout, so the belt system on the vehicle needs to match that arrangement. The unit also has an internal regulator and no connector for revolution counter, which means the charging system and plug arrangement should be checked against the original alternator before purchase.

The listed fitment references include Fiat and Fiat Ducato applications, but the safest buying method is still to compare the existing unit on the vehicle with the supplied measurements and connector details. If the old alternator has a different pulley section, a different mounting pattern, or a different connector setup, this unit may not be suitable even if the vehicle model appears in the application list.

This alternator is supplied new and carries a one year warranty, which is useful for buyers who want a fresh unit rather than a remanufactured one. Even so, correct installation depends on the vehicle’s belt path, mounting ears, and electrical connection matching the listed configuration. Taking a few minutes to confirm those items usually avoids unnecessary returns and fitting delays.

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 439339 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 67mm, Pivot Hole Diameter M10x1.5 / 10, Pulley Outside Diameter 60mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 178mm, Alternator Charge Current [A] 120.

Additional published details for cross-checking include Connector / Clamp No Connector for Revolution Counter, Product Group 2 ALTERNATORS, Part No. 439339, Brand VALEO, Description Valeo Alternator 12V 120A, Adjusting Hole Diameter 8, Pin Code IR189, Power Rating (Amp) 120, Pulley Section 6 Groove.

Valeo Alternator 12V 120A. Part number 439339 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439339, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FIAT DUCATO, FIAT DUCATO 2000, FIAT DUCATO 2001, FIAT DUCATO 2002. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number 439339, the 12V 120A specification, and the mounting and pulley measurements before ordering. Application references for Fiat and Fiat Ducato are provided, but the final match should be checked against the vehicle’s original alternator and charging system details.
