OEX Alternator 12V 120A Valeo Style VXA015

The OEX Alternator 12V 120A Valeo Style, part number VXA015, is a new rotating electrical unit supplied as each. It is rated at 12 volts and 120 amps, with a 6 groove pulley and internal regulator, so it is important to match those details to the vehicle’s original charging setup before ordering.

This alternator uses a single leg mount with a 56 mm mount leg thickness, 156 mm mount centre to centre, and a 10 mm adjusting hole diameter. The pulley outside diameter is 50 mm, and the unit weighs 6.5 kg, so it is a substantial component and worth checking against the original part rather than relying on appearance alone.

The unit is described as Valeo style and suits Valeo applications. Fitment data provided points to Mercedes-Benz applications, including C-Class, E-Class, S-Class, SL and SLK variants across a range of years. Because alternator mounting and pulley details can vary within the same model family, the part number and physical measurements should be confirmed against the vehicle already fitted.

Application and Buying Notes

Alternators are best matched by more than voltage and amp rating alone. This unit is 12V, 120A, uses an internal regulator, and has a 6 groove pulley, so those details should line up with the existing charging system. If the vehicle originally used a different pulley section, mount arrangement or regulator setup, the alternator may not be a direct match even if the model badge is similar.

The physical measurements matter just as much as the electrical rating. With a single leg mount, 56 mm mount leg thickness, 156 mm mount centre to centre, 10 mm adjusting hole diameter and 50 mm pulley outside diameter, the safest approach is to compare the original unit side by side. These dimensions help avoid ordering a part that looks close but does not sit correctly in the bracket.

The listed applications point towards Mercedes-Benz C-Class, E-Class, S-Class, SL and SLK vehicles, but the fitment data should be treated as a guide only. Within the same vehicle range there can be differences in alternator mounting and pulley configuration, so the part number VXA015 and the original alternator details remain the key checks. If the old unit is available, matching its label and dimensions is the most reliable way to confirm the correct replacement.

For commercial use, the warranty listed is 1 year, while passenger use is covered for 3 years. Warranty terms do not replace fitment checking, but they do provide useful context if you are selecting a replacement for a work vehicle or private car. If there is any doubt, compare the vehicle information, original alternator, and the dimensions listed here before ordering.

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 VXA015 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.
