Valeo Alternator 12V 180A 439537

Valeo Alternator 12V 180A, part number 439537, is a new rotating electrical component supplied as each. It is rated at 180A and 12V, with an internal regulator, making it a direct spec-driven replacement candidate where those electrical details, mounting style, and connector arrangement match the vehicle application.

This alternator uses a 6 groove pulley with a 52mm pulley outside diameter, a twin leg alternator mount, and a double pivot lever fastening type. The listed position or degree is L 47, and the unit weighs 7.76kg, so it is important to compare the physical layout as well as the electrical output before ordering.

The connector / clamp listing notes no connector for revolution counter, which is a useful checkpoint when matching the existing unit. The product is marked new, carries no warranty, and is identified under Valeo brand details with Pin Code IR182.

Where the alternator sits in the charging system, matching the part number 439537 and the stated 12V, 180A specification is essential. If the vehicle has been modified, or if the existing alternator has a different pulley, mount, or connector arrangement, the safest approach is to verify those details against the removed part first.

Application and Buying Notes

Before ordering, compare the removed alternator to the listed details for part number 439537: 12V, 180A, internal regulator, 6 groove pulley, 52mm pulley outside diameter, twin leg mount, and double pivot lever fastening type. These are the practical checks that matter when confirming a charging system replacement.

The connector detail is just as important as the electrical rating. This unit is listed with no connector for revolution counter, so if the original alternator uses a different connector setup, the part may not suit without further verification. Matching the physical plug arrangement and any attached wiring style should be part of the decision.

The fitment information supplied points to BMW applications, including BMW 5, BMW 6, BMW 7, and BMW X5, with sample listings shown for BMW 5 2003, 2004, and 2005, and BMW 6 applications extending through 2009 in the grouped preview. That still does not replace a direct check against the vehicle’s existing alternator, because alternator variants can differ within the same model range.

The unit weight is 7.76kg, which can be helpful when comparing to the removed part and when planning handling or freight expectations. As with any charging component, confirm the mount shape, pulley alignment, and regulator style before fitting, especially where previous repairs or model changes may have altered the vehicle specification.

This alternator is described as a new Valeo unit and carries no warranty. That makes it especially important to verify all compatibility points up front, since the correct match should be established by part number, application details, and the physical unit on the vehicle rather than assumptions about model overlap.

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 439537 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.
