Valeo Alternator 12V 180A 439884

This Valeo alternator is a 12V, 180A unit with part number 439884, supplied new and covered by a one year warranty. It is listed as a Valeo unit with internal regulation, clockwise rotation, and a 6 groove pulley, so it is important to compare the physical mounting and electrical details carefully before ordering.

The alternator uses a twin leg mount with three-point mounting, 81mm inside mounting legs, a 162mm mount centre to centre measurement, and 10mm pivot and adjusting hole diameters. Those measurements are the practical checks that help confirm the unit will sit and align correctly in the vehicle application.

It is described as a leading OE manufacturer and supplier for many euro vehicles, and the fitment data supplied points to Fiat Ducato and Iveco Daily applications across multiple years. As always, the part number 439884 and the listed mount and pulley details should be checked against the original unit already fitted to the vehicle.

Application and Buying Notes

Before buying, compare the part number 439884 with the original alternator and check the mounting layout on the vehicle. The key physical points here are the twin leg mount, three-point fastening, 81mm inside mounting legs, 162mm mount centre to centre, and 10mm pivot and adjusting holes. Those dimensions need to match the existing setup, not just the vehicle badge.

The electrical side also matters. This unit is 12V and rated at 180A, with an internal regulator and no connector for revolution counter. That makes it important to confirm the vehicle’s charging system wiring and connector arrangement before fitting, especially where the original alternator used a different plug style or sensor connection.

Pulley alignment is another point worth checking. The alternator has a 55mm outside diameter pulley with a 6 groove section and clockwise rotation. The belt must suit the pulley type and the drive direction must match the application, otherwise the unit may not operate correctly even if the mounting appears close.

If you are working on a Fiat Ducato or Iveco Daily application, use the year range provided as a guide only and confirm the actual vehicle build and the old unit’s details. Model names alone are not enough when alternators vary by mount style, regulator type, pulley section, or connector arrangement.

This is a new Valeo alternator, which is useful when you want to replace a worn charging unit rather than repair one. The one year warranty gives a clear warranty period, but the correct installation still depends on matching the listed measurements and electrical specification to the vehicle currently in front of you.

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 439884 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 439884, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FIAT DUCATO, FIAT DUCATO 2006, FIAT DUCATO 2007, FIAT DUCATO 2008, IVECO DAILY, IVECO DAILY 2006. 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.

Compatibility note: Confirm compatibility by matching part number 439884, the 12V 180A specification, the twin leg three-point mounting, and the 6 groove pulley details to the vehicle and the original alternator before purchase.
