OEX Alternator 12V 150A Valeo Style VXA934

The OEX Alternator VXA934 is a new 12V, 150A unit in a Valeo style configuration, supplied with an internal regulator and a 6 groove pulley. It is listed as a quad leg alternator with a 139mm mount centre to centre measurement and 46mm between the inside mounting legs, so the physical mounting pattern needs to be checked carefully against the existing unit before purchase.

This alternator suits Valeo applications and is a rotating electrical component from the OEX range. It weighs 6.9kg, has a CW rotation, and uses an M10x1.5 / 10 pivot hole diameter. Those details matter when you are comparing it to the unit already fitted in the vehicle, especially where bracket style, pulley layout, or mounting dimensions vary between similar-looking alternators.

OEX lists this alternator with a 3 year passenger / 1 year commercial warranty. It is marked as a new part, not remanufactured, and is designed as an aftermarket replacement for vehicles that match the specified Valeo-style alternator layout and electrical output.

For buyers checking a replacement alternator, the key points on this unit are the 12V system voltage, 150 amp output, internal regulator, 53.5mm pulley outside diameter, and 6 groove belt configuration. Matching those details to the vehicle and the removed alternator is the safest way to avoid installation issues.

Application and Buying Notes

Before ordering, compare the removed alternator against part number VXA934 and check the physical mounting pattern. The listed quad leg mount, 139mm mount centre to centre, 46mm inside mounting legs, and M10x1.5 / 10 pivot hole diameter are the main checkpoints when confirming whether this Valeo style unit will suit the vehicle.

The electrical details are just as important as the mounting details. This alternator is 12V and rated at 150A, with an internal regulator and CW rotation. The pulley is 6 groove with a 53.5mm outside diameter, so belt type and drive arrangement need to match the existing setup.

The fitment data points to Ford Fiesta and Volvo C30 and V40 applications, but those model names alone are not enough to confirm suitability. Matching the exact year, engine arrangement, and alternator shape on the vehicle is still necessary, because alternators with similar output can differ in mounting, pulley section, and regulator layout.

If you are replacing an existing Valeo unit, use the old alternator as the reference point first. Check the part number if it is visible, then compare the mount style, pulley grooves, rotation direction, and overall weight of 6.9kg. Those checks are the most practical way to reduce the risk of ordering the wrong unit.

For commercial use, the warranty is listed separately at 1 year, while passenger applications carry 3 years. That distinction is worth noting when the vehicle is used differently from a standard passenger car, or when the alternator is being replaced in a mixed fleet environment.

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 VXA934 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.
