Valeo Alternator 12V 180A 439652

The Valeo Alternator 12V 180A, part number 439652, is a new rotating electrical component supplied as each unit. It is specified with a 12 volt system, 180 amp charge current, and an internal regulator, so it suits applications that match those electrical and mounting details rather than being treated as a universal replacement.

This alternator uses a twin leg mounting arrangement with a double pivot lever fastening type. The listed mounting measurements are 126mm mount centre to centre and 75mm inside mounting legs, with a 54mm outside pulley diameter and a 6 groove pulley section. Those details are important when checking physical interchange, especially on euro vehicle applications where bracket and pulley alignment must match closely.

Valeo identifies this unit as a new alternator and lists it under rotating electrical parts. The connector detail is recorded as no connector for revolution counter, and the position / degree is shown as L 95. As with any alternator replacement, confirm the part number 439652 and compare the mounting, pulley, and connector details before purchase.

Fitment guidance

• Fitment is only partially referenced for BMW applications.
• BMW 3 is listed in the supplied fitment information, including model years 2008, 2009, 2010, 2011, and 2012.
• BMW X3 is also listed in the supplied fitment information, including model years 2007, 2008, 2009, 2010, and 2011.
• Because the fitment data is not fully detailed here, the part number 439652 and the mounting and pulley measurements should be checked against the vehicle’s existing alternator before ordering.

Application and Buying Notes

When replacing an alternator, the safest check is to compare the part number 439652, the 12V rating, and the 180A charge current against the vehicle already fitted. Electrical output is only one part of the match; the mounting layout must also line up with the engine bracket and belt drive system.

This Valeo unit is listed with a twin leg mount, double pivot lever fastening, 126mm mount centre to centre, and 75mm inside mounting legs. If those dimensions differ from the original alternator, the part may not physically fit even if the electrical rating appears similar.

The pulley details matter as well. This alternator has a 54mm outside diameter pulley with a 6 groove section. Belt alignment and groove count need to suit the existing drive belt setup, otherwise the alternator may not run correctly in service.

The connector detail is also worth checking. The listing states no connector for revolution counter, so buyers should compare the plug arrangement and any auxiliary connection points on the existing unit before fitting. This is especially important where the original alternator has a different sensing or counter output arrangement.

If you are matching a BMW 3 or BMW X3 application, use the vehicle details as a guide only and confirm against the actual alternator removed from the vehicle. The listed fitment does not replace a physical check of the old unit, the pulley profile, or the mounting arrangement.

This alternator is a one year warranty item and weighs 7.51kg. Weight alone does not confirm interchange, but it can be a useful comparison point when assessing whether the replacement unit is consistent with the original part.

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 439652 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.
