Valeo Alternator 12V 230A 439636

The Valeo Alternator 12V 230A is a new rotating electrical unit supplied by Valeo, part number 439636, with OEM number FG23S010. It is rated at 12 volts and 230 amps, and it uses an internal regulator for direct fastening installation.

This alternator is listed with a single leg mount, 174mm mount centre to centre, and a mount leg thickness of 83mm. It also uses a 7 groove pulley with a 50mm outside diameter, which are important points to match against the removed unit before ordering.

The unit is supplied with no connector for a revolution counter and is marked as having no insulated return. It weighs 7.44kg and is sold individually as each, with a one year warranty.

Valeo is identified here as a leading OE manufacturer and supplier for many euro vehicles. That makes this a sensible replacement choice where the existing unit matches the 12V 230A specification, the mounting arrangement, and the listed connector and pulley details.

Application and Buying Notes

Before ordering, compare the removed alternator with part number 439636 and OEM number FG23S010. The key match points on this unit are 12V, 230A, internal regulation, single leg mounting, direct fastening, and a 7 groove pulley with a 50mm outside diameter.

The physical dimensions matter on this alternator. Check the 174mm mount centre to centre and the 83mm mount leg thickness against the existing unit, because mounting style and bracket geometry need to line up correctly for installation.

Connector arrangement should also be verified carefully. This Valeo unit is listed with no connector for a revolution counter, so a vehicle that requires a different connector setup should not be matched by guesswork.

Application coverage shown for this part includes BMW 5, BMW 6, BMW 7, BMW X5 and BMW X6 references. Even where the vehicle family appears in the fitment list, final confirmation should still be made against the part number, pulley profile, mount type and electrical connection details on the vehicle being repaired.

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 439636 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.
