Application and Buying Notes

Before ordering, match the part number DXA4033 and compare the physical mounting details on the vehicle: 147mm mount centre-to-centre, 64mm mount leg thickness, and 10mm pivot and adjusting holes. Those measurements are often the most useful first check when replacing a Denso style alternator, especially where several similar units are used across different vehicle applications.

The alternator is specified as 12V and 120A, so it needs to suit the vehicle’s charging system and electrical demand. The internal regulator and 6 groove pulley are also important points to verify, because pulley section and regulator type must align with the existing installation for a clean fit and correct operation.

Fitment references are provided for Hyundai and Kia applications, including Grandeur, Santa Fe, Sonata, Terracan, Sorento and Sportage. Even where a vehicle family is listed, the safest approach is to confirm the exact application against the vehicle details already fitted, as alternators can vary by engine, model year, or build specification.

If you are replacing an alternator that has been removed from the vehicle, compare the old unit’s shape, mounting ear arrangement, pulley type, and connector arrangement before purchase. The listing confirms this is a new OEX alternator with a Denso style layout and a single leg mount, so the match needs to be checked on both the physical dimensions and the application reference.

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 DXA4033 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 DXA4033, 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.
