OEX Alternator 12V 120A Valeo Style VXA025

The OEX VXA025 is a new 12V alternator rated at 120A and built in a Valeo style configuration. It is supplied as a twin leg alternator mount design with a 6 groove pulley, and it is listed with internal regulator control.

This unit suits Valeo applications and carries the note to confirm by OE number because regulator functions can vary between applications. That is the key checkpoint on this part: the physical alternator style and 120A output are only part of the matching process.

Measured dimensions include 58mm inside mounting legs, a 170mm mount centre-to-centre measurement, M10x1.25 / 10 pivot hole diameter, and an M8x1.25 adjusting hole diameter. The pulley outside diameter is 58mm and the unit weight is 5.04kg.

Application and Buying Notes

Start with the OE number and the regulator function. This alternator is a Valeo style unit with an internal regulator, and the listing specifically advises confirming by OE number because regulator functions can differ between applications. If the OE number does not match the vehicle’s original unit, the alternator may look similar but still be incorrect.

Check the physical mount dimensions before ordering. The unit has 58mm inside mounting legs, a 170mm mount centre-to-centre measurement, M10x1.25 / 10 pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those measurements matter just as much as the 12V and 120A rating when comparing against the original alternator.

Make sure the pulley arrangement matches the vehicle’s belt setup. This alternator has a 58mm pulley outside diameter and a 6 groove pulley section, so the belt profile and pulley size should be compared carefully with the existing part. The unit is new, weighs 5.04kg, and is listed for Valeo applications, so it is best treated as a direct comparison part rather than a universal replacement.

For buyers working on Hyundai or Kia applications, use the fitment references as a guide only. Models listed include Elantra, i30, i40, i45, ix35, Tucson, Cerato, Cerato Koup, Rondo, Soul and Sportage, with sample year references shown for Hyundai Elantra and Kia Cerato. Final confirmation should still be made against the OE number, regulator function, and mounting measurements before the part is fitted.

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 VXA025 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.

For part number VXA025, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching the OE number, regulator function, mounting measurements, pulley type, and vehicle application details before ordering. The part is listed as a Valeo style 12V 120A alternator with internal regulator and twin leg mounting, but OE number verification is essential.
