OEX Alternator 12V 120A Valeo Style VXA912

The OEX Alternator VXA912 is a new 12V, 120A unit in Valeo style, supplied as each and identified with IR167 pin code. It uses an internal regulator, a 6 groove pulley, and a quad leg alternator mount, so the mounting style and belt drive need to match the vehicle application before purchase.

This alternator has inside mounting legs of 60mm, a mount centre-to-centre measurement of 127mm, and an M8x1.25 / 9 pivot hole diameter with the same M8x1.25 / 9 adjusting hole diameter. Those measurements are the key checks for anyone comparing an existing unit to this replacement.

OEX positions this alternator range as a quality aftermarket option backed by a three-year warranty. The brand notes ISO9001 certified factories and OE supplier experience, which is useful context for buyers who want a replacement rotating electrical unit with defined specifications rather than a guess based on appearance alone.

Application and Buying Notes

The most important buying check on this alternator is matching the part number VXA912 and confirming the unit style against your existing Valeo-style alternator. Mounting layout matters here: the unit has a quad leg alternator mount, 60mm inside mounting legs, and 127mm mount centre-to-centre, so those dimensions should be compared carefully before ordering.

The pulley is a 6 groove design with a 53mm outside diameter, and the regulator is internal. If your original unit differs in pulley section, regulator type, or mounting geometry, it may not be a direct swap even if the alternator is also 12V.

Fitment references are provided for MERCEDES-BENZ C-CLASS and NISSAN X-TRAIL applications, including 2013 to 2018 C-CLASS and NISSAN X-TRAIL 2013. Use those references as a starting point only and verify the actual installed unit, as alternators can vary by engine, electrical system, and mounting arrangement.

If you are replacing an existing alternator, match the pivot and adjusting hole diameter as well as the electrical specification. The pivot and adjusting holes are both listed as M8x1.25 / 9, and the unit is listed as 12V 120A with no insulated return, so those details should align with the vehicle’s original setup.

At 6.24kg, this is a substantial rotating electrical component, so careful comparison with the old unit is worthwhile before fitting. A direct visual match is not enough on its own when the pulley section, regulator type, and mounting dimensions are all relevant to compatibility.

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 VXA912 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. VXA912, Brand OEX, Description OEX Alternator 12V 120A Valeo Style, Adjusting Hole Diameter M8x1.25 / 9, Pin Code IR167, Power Rating (Amp) 120, Pulley Section 6 Groove, Suits Unit Make Valeo.

OEX Alternator 12V 120A Valeo Style. Part number VXA912 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad 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 VXA912, 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.

Available application references include MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 2014, MERCEDES-BENZ C-CLASS 2015, MERCEDES-BENZ C-CLASS 2016, NISSAN X-TRAIL, NISSAN X-TRAIL 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.

The listed warranty is Three Years. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number VXA912, the Valeo style designation, and the listed mounting and electrical details before purchase. Always compare the existing alternator’s pulley, mounting layout, regulator type, and hole measurements with the vehicle application.
