OEX Alternator 12V 90A Valeo Style VXA057

The OEX VXA057 alternator is a new 12V, 90A unit in Valeo style, supplied as each and listed under rotating electrical. It uses an internal regulator and a twin leg alternator mount, with a 5 groove pulley and a pulley outside diameter of 57mm.

Key mounting dimensions are provided for checking against the original unit: inside mounting legs are 46mm, the mount centre-to-centre is 167mm, the pivot hole diameter is M10x1.25 / 10, and the adjusting hole diameter is M8x1.25. The unit weighs 4.72kg.

This alternator is listed as suit unit make Valeo, with part number VXA057 and pin code IR207. The product note advises confirmation by OE number due to different regulator functions, which is important when matching replacement alternators.

Warranty cover is listed as 3yr Passenger and 1yr Commercial. That makes correct identification before purchase especially important, because the regulator type, mounting layout, and pulley specification all need to align with the vehicle’s original setup.

Application and Buying Notes

Before ordering, compare the original alternator’s OE number with VXA057, and check that the regulator function matches. The note on this unit is explicit: different regulator functions can change whether the alternator is the correct replacement, even where the mount and pulley look similar.

The physical details matter here. This alternator is 12V and rated at 90A, with a twin leg mount, 46mm inside mounting legs, 167mm mount centre-to-centre, an M10x1.25 / 10 pivot hole, and an M8x1.25 adjusting hole. Those dimensions should be checked against the removed unit, not guessed from appearance.

Pulley layout also needs to match. This alternator uses a 5 groove pulley with a 57mm outside diameter. If the belt style or pulley arrangement on the vehicle differs, the part may not be suitable even if the casing is similar.

The listed application preview includes Hyundai Accent, Hyundai i30, and Kia Rio, with Hyundai Accent shown across 2010 to 2019 and Kia Rio shown in the preview, including 2017. That is helpful as a guide, but it is not a substitute for checking the exact OE reference and mounting arrangement on the vehicle.

Because this is a new alternator with a 3yr Passenger and 1yr Commercial warranty, correct selection at the start is the safest approach. The weight is 4.72kg, and the unit is supplied as a Valeo style alternator, so the shape and mounting points should be checked carefully against the original part before installation.

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 VXA057 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 90A Valeo Style - See Note. Part number VXA057 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 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number VXA057, 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.

Compatibility note: Please confirm compatibility by matching the OE number, regulator function, mounting dimensions, pulley section, and vehicle application before purchase. The supplied note specifically advises checking by OE number due to different regulator functions.
