OEX Alternator 12V 120A Delphi Style DXA498

The OEX DXA498 is a new 12V alternator rated at 120A and built in a Delphi style application. It is listed with an internal regulator, a twin leg alternator mount, and a 6 groove pulley, so it is intended for applications that match those mounting and drive details.

This unit is noted as replacing the original alternator with a two terminal plug. That connection detail is important when checking a replacement, because the plug style needs to match the vehicle wiring before purchase. The alternator is supplied as a new unit, not remanufactured, and weighs 6.62kg.

Key dimensions include 57mm inside mounting legs, a 10mm pivot hole, M10x1.5 adjusting hole, and 183mm mount centre to centre. Those measurements are the practical checks that help confirm whether the alternator will physically locate the same way as the unit being replaced.

Application and Buying Notes

Before ordering, confirm the part number DXA498 against the existing alternator and compare the mounting layout. The 57mm inside mounting legs, 10mm pivot hole, M10x1.5 adjusting hole, and 183mm mount centre to centre are the sort of measurements that matter when matching a replacement alternator.

The pulley details also need to line up with the vehicle’s belt drive. This unit has a 56mm pulley outside diameter and a 6 groove pulley section, so the belt profile and pulley configuration should be checked against the original unit rather than assumed.

Because this alternator is described as a Delphi style unit with an internal regulator, the electrical connection and regulator arrangement need to be the same as the unit being removed. The listing note says it replaces an original alternator with a two terminal plug, which is the key compatibility checkpoint on the wiring side.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That does not change the need to confirm fitment first, especially on vehicles where alternator styles can vary within the same model range.

If you are comparing against a worn or dirty original alternator, clean the unit enough to read the part details, plug style, and mounting points properly. Matching by appearance alone is not enough when the application relies on the DXA498 part number, Delphi style fitment, and specific dimensions.

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 DXA498 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 120A Delphi Style - See Note. Part number DXA498 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 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 DXA498, 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 HOLDEN CAPTIVA 5, HOLDEN CAPTIVA 5 2007, HOLDEN CAPTIVA 5 2008, HOLDEN CAPTIVA 5 2009. 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 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by matching the part number DXA498, the Delphi style application, the two terminal plug note, and the listed mounting and pulley dimensions before ordering.
