Valeo Alternator 12V 180A Part No. 439709

Valeo Alternator 12V 180A, part no. 439709, is a new rotating electrical unit supplied as an each item for applications that match the listed mounting and pulley details. It carries an internal regulator, 180A charge current, and a 6 groove pulley, so it is a specific alternator rather than a universal substitute.

This unit is identified with Valeo brand details, pin code IR182, and a three-point mounting arrangement with twin leg alternator mount. Key physical measurements include 75mm inside mounting legs, 126mm mount centre to centre, a M10x1.5 pivot hole diameter, and a 10mm adjusting hole diameter.

The pulley outside diameter is 53.5mm and the alternator is listed with a L 95 position / degree notation. It is designed for 12V systems and weighs 7.73kg, so matching the electrical system and mounting layout matters when checking replacement suitability.

Application and Buying Notes

Before ordering, compare the part number 439709 and the Valeo identification with the alternator currently fitted to the vehicle. The listed mounting pattern is three-point with twin leg alternator mount, 75mm inside mounting legs, and 126mm mount centre to centre, so those measurements should be checked carefully against the removed unit.

The pulley specification is important on this alternator. It uses a 6 groove pulley with a 53.5mm outside diameter, and the unit is listed for 12V charging at 180A. If the belt profile, charging system voltage, or current requirement does not align with the vehicle setup, it should not be treated as a direct match.

The internal regulator and the note of no connector for revolution counter are also worth confirming before purchase. Electrical plug style and wiring arrangement can vary between applications, so compare the existing connector and harness layout with the listed details rather than relying on appearance alone.

Weight is listed at 7.73kg, which can be useful when comparing replacement units that may differ in casing style or pulley arrangement. The Valeo brand note indicates it is a leading OE manufacturer and supplier for many euro vehicles, but the application still needs to be verified by measurement and part reference.

If the existing alternator carries a different pulley section, a different mounting ear spacing, or a different pivot arrangement, the safest approach is to confirm the replacement against the removed part first. Matching the physical dimensions is just as important as matching the 12V and 180A electrical rating.

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 439709 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 75mm, Pivot Hole Diameter M10x1.5, Pulley Outside Diameter 53.5mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 126mm, Alternator Charge Current [A] 180.

Additional published details for cross-checking include Fastening Type Three-point mounting, Weight 7.73kg, Product Group 1 ROTATING ELECTRICAL, Part No. 439709, Brand VALEO, Description Valeo Alternator 12V 180A, Adjusting Hole Diameter 10, Pin Code IR182, Power Rating (Amp) 180, Pulley Section 6 Groove.

Valeo Alternator 12V 180A. Part number 439709 should be checked first. Listed voltage is 12. Listed output rating is 180. 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 439709, 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 BMW 3, BMW 3 2004, BMW 3 2005, BMW 3 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.

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: Please confirm fitment by comparing part number 439709, Valeo identification, mounting measurements, pulley details, and electrical connector arrangement with the vehicle’s existing alternator before purchase.
