OEX Alternator 12V 130A Denso Style DXA559

The OEX Alternator DXA559 is a 12V, 130A unit in a Denso style configuration, supplied new and intended for rotating electrical applications where the original fitment matches the listed mounting and connection details. It uses an internal regulator and is supplied with a 6 groove pulley, with only 2 pins required for connection.

Key physical details include a quad leg alternator mount, 43mm inside mounting legs, 162mm mount centre-to-centre, 11mm pivot hole diameter, and 11mm adjusting hole diameter. The pulley outside diameter is 52mm, and the unit weighs 5.84kg.

This alternator is listed under OEX part number DXA559 and pin code IR104, with the unit identified as a Denso suit. As with any replacement alternator, matching the electrical specification alone is not enough; the mounting style, pulley type, connector arrangement, and spacing all need to line up with the vehicle application.

Application and Buying Notes

Before ordering, confirm the vehicle uses the same Denso style alternator arrangement and that the replacement matches the 12V, 130A output, 6 groove pulley, and internal regulator listed here. The connector requirement is specific: only 2 pins are required for connection, so the plug style needs to match the original unit.

The mounting dimensions matter just as much as the electrical rating. Check the quad leg mount, 43mm inside mounting legs, 162mm mount centre-to-centre, and the 11mm pivot and adjusting holes against the existing alternator. Even a small difference in mounting or pulley arrangement can prevent correct installation.

The fitment information supplied for this part includes Hyundai Grandeur, Hyundai Santa Fe, Hyundai Sonata, Hyundai Tiburon, Hyundai Tucson, and Kia Carnival / Grand Carnival, plus Kia Sorento. That still does not replace a direct part number or application check, because alternators can vary between engine, model year, and electrical setup.

If you are comparing against a removed alternator, the most useful checks are the part number DXA559, the Denso style identification, the 52mm 6 groove pulley, and the 2-pin connection. Those details provide the clearest match points when the vehicle listing alone is not enough to confirm 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 DXA559 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.

For part number DXA559, 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: Please confirm fitment using the part number DXA559, the Denso style application, and the listed mounting, pulley, and connector details before purchasing. Vehicle model names can help narrow the search, but the final check should always be against the original alternator and application specifics.
