Application and Buying Notes

Before ordering, confirm the existing alternator matches VXA031 or the supplied Valeo style application, because alternator fitment depends on the unit make, pulley configuration, and mounting dimensions. This unit is 12V with a 130A output, so it should only be considered where the vehicle’s electrical system and original alternator specification align with those details.

The mounting dimensions matter just as much as the electrical rating. Check the twin leg mount, 51mm inside mounting legs, M10 x 1.25 / 10.5 pivot hole diameter, and 163mm mount centre to centre against the unit being replaced. A pulley mismatch can also stop a correct installation, so compare the 5 groove pulley and 57mm outside diameter before purchase.

This alternator is a new OEX unit and includes an internal regulator, which is useful to verify if the existing setup uses the same regulator arrangement. The listed weight is 6.3kg, and while that is not a fitment rule by itself, it can help when comparing the replacement against the removed part.

The fitment references provided point to Hyundai i40 applications across 2011 to 2018, but the safest approach is still to match the vehicle application with the part number and the physical measurements. If the current alternator differs in mount style, pulley section, or connector arrangement, pause and check before fitting.

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 VXA031 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.

OEX Alternator 12V 130A Valeo Style. Part number VXA031 should be checked first. Listed voltage is 12. Listed output rating is 130. 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 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number VXA031, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number VXA031, Valeo style application details, 12V system requirement, 130A output, and the listed mounting and pulley measurements against the vehicle and the removed alternator before ordering.
