OEX Alternator 12V 90A Valeo Style VXA021

The OEX Alternator VXA021 is a new 12V, 90A unit built in Valeo style and sold as a single each. It uses an internal regulator, a twin leg alternator mount, and a 6 groove pulley, so those physical details matter when comparing it against the vehicle you have in front of you.

This alternator is listed with an inside mounting leg spacing of 58mm, a mount centre to centre dimension of 171mm, a pivot hole diameter of M10x1.25 / 10, and an adjusting hole diameter of M8x1.25. Those dimensions are important because alternators can look similar while differing in bracket layout and bolt sizing.

The connection note is equally important: only 2 pins are required for connection, and it is recommended to confirm by OE number due to different regulator functions. If you are matching an existing Valeo-style alternator, checking the part number VXA021 and the OE application details before ordering is the safest approach.

Application and Buying Notes

When comparing this alternator, focus first on the fitment-critical measurements: 58mm inside mounting legs, 171mm mount centre to centre, M10x1.25 / 10 pivot hole diameter, and M8x1.25 adjusting hole diameter. Those figures need to align with the alternator mounting position on the vehicle, otherwise the unit may not bolt up correctly even if the electrical rating is close.

The unit is Valeo style and is specified for Valeo as the unit make, but alternator appearance alone is not enough for a reliable match. The note to confirm by OE number is especially relevant here because different regulator functions can exist across similar-looking alternators, and this unit uses an internal regulator with pin code IR104.

Electrical output is rated at 12V and 90A, which tells you the charging specification to compare against the original alternator. The pulley is a 6 groove design with a 58mm outside diameter, so the belt type and pulley layout also need to be checked against the vehicle’s existing setup before purchase.

Connection details should be checked carefully. This alternator only requires 2 pins for connection, which may differ from other Valeo-style applications. If your original unit uses a different plug arrangement or regulator behaviour, the alternator may not be a direct match even though the physical mounting looks similar.

For workshop or parts-counter use, the most reliable buying method is to compare the original alternator part number, the vehicle application, and the listed dimensions together. The 3 year passenger / 1 year commercial warranty adds useful purchasing confidence, but it does not replace a fitment check on the mounting, pulley, and connector details.

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 VXA021 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. VXA021, Brand OEX, Description OEX Alternator 12V 90A Valeo Style - See Note, Adjusting Hole Diameter M8x1.25, Pin Code IR104, Power Rating (Amp) 90, Pulley Section 6 Groove, Suits Unit Make Valeo.

OEX Alternator 12V 90A Valeo Style - See Note. Part number VXA021 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number VXA021, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI ELANTRA, HYUNDAI ELANTRA 2010, HYUNDAI ELANTRA 2011, HYUNDAI ELANTRA 2012, KIA CERATO, KIA CERATO 2013. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment using part number VXA021, the OE number for the original unit, and the mounting and connector details before ordering. Valeo-style alternators can vary in regulator function and plug arrangement, so the physical and electrical specifications should be checked together.
