OEX Alternator 12V 90A Valeo VXA023

The OEX Alternator VXA023 is a new 12V, 90A unit suited to Valeo applications and supplied as an each item. It uses an internal regulator, a twin leg alternator mount, and a 4 groove pulley with a 58mm outside diameter.

Key mounting details matter with this alternator: the inside mounting legs measure 55mm, the mount centre to centre is 172mm, the pivot hole diameter is 8mm, and the adjusting hole is M8x1.25. Those dimensions should be checked against the vehicle or the original unit before ordering.

This unit is listed with pin code IR104 and the note states that only 2 pins are required for connection. It also advises confirming by OE number because regulator functions can vary, so matching the part number and connection style is important before fitment.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. The listed warranty is 3 years for passenger use and 1 year for commercial use.

Fitment guidance

• Fitment is not fully verified here, so confirm the part number VXA023 against your original alternator before purchase.
• Check that the vehicle uses a Valeo alternator and that the connection uses the IR104 pin code with only 2 pins required.
• Measure the mounting points against the supplied dimensions: 55mm inside mounting legs, 172mm centre to centre, 8mm pivot hole, and M8x1.25 adjusting hole.
• Confirm the pulley is a 4 groove type and that the 58mm outside diameter matches the existing unit.
• Because regulator functions can vary, matching by OE number is advised rather than relying on appearance alone.

Application and Buying Notes

Before ordering, compare the alternator you are replacing with part number VXA023 and check that it is a Valeo unit. The connection detail is important here, because this alternator uses pin code IR104 and the note specifies that only 2 pins are required for connection.

Mounting dimensions should be checked carefully. This alternator has 55mm inside mounting legs, a 172mm mount centre to centre measurement, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. If any of those points differ from the vehicle bracket or original unit, it may not be the correct match.

Pulley setup also needs attention. The unit is a 12V, 90A alternator with a 4 groove pulley and a 58mm outside diameter, so the belt arrangement must suit those details. A mismatch in pulley section or size can create installation problems even when the unit looks similar.

The listed warranty is 3 years for passenger use and 1 year for commercial use. If you are fitting this to a commercial vehicle, check that the application and duty cycle suit the warranty terms before purchase.

This is a new alternator, not a remanufactured unit, and it weighs 4.76kg. Those points can be useful when comparing against the removed alternator and when confirming that the replacement is the same general build and application type.

If you are unsure, compare the original alternator label, the OE number, the connector style, and the pulley details side by side. The note specifically advises confirming by OE number due to different regulator functions, which is the safest way to avoid the wrong part.

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 VXA023 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.
