OEX Alternator 12V 85A Delco Style DXA481

The OEX Alternator DXA481 is a new 12V, 85A unit in Delco style, supplied as an alternator for rotating electrical applications. It uses an internal regulator and a 5 groove pulley, with a pulley outside diameter of 62mm and twin leg mounting. Those details matter when matching the unit to the vehicle, especially where the original alternator layout and pulley arrangement need to be the same.

This alternator is listed with a part number of DXA481 and a pin code of IR23. The mounting measurements provided are 80mm between the inside mounting legs, 165mm mount centre to centre, and an M8 x 1.25 adjusting hole diameter with an 8mm pivot hole diameter. Those are the key physical checks to confirm before ordering, particularly if you are replacing a Delco unit and need the bracket spacing to line up correctly.

OEX states the product is sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing, and quality control procedures. The unit is covered by a 3 year passenger / 1 year commercial warranty, which gives you a clear warranty reference when selecting a replacement alternator for the correct application.

Application and Buying Notes

Before ordering, match the part number DXA481 and compare the physical measurements against the alternator already fitted to the vehicle. The supplied dimensions include 80mm inside mounting legs, 165mm mount centre to centre, an 8mm pivot hole, and an M8 x 1.25 adjusting hole, so these are the best checks for bracket and adjustment alignment.

The pulley setup also needs attention. This unit is specified with a 5 groove pulley and a 62mm pulley outside diameter, so it should only be considered where the belt arrangement matches. A belt profile or groove count that does not line up can stop the alternator from fitting correctly, even if the electrical output looks suitable on paper.

Output and regulator type are equally important. This is a 12V, 85A alternator with an internal regulator, so it should be compared with the original unit’s charging specification and control style. Where the vehicle originally used a different voltage, amperage, or external regulation arrangement, the correct replacement may be different.

The fitment list includes DAEWOO 1.5I, CIELO, ESPERO, KALOS, LANOS, NUBIRA, TOYOTA HILUX, and TOYOTA TARAGO, but these names alone are not enough to confirm the right part for every variant. Check the exact vehicle application, year where shown, and the original alternator details before purchasing, especially if the vehicle has been modified or if parts have been changed previously.

Weight is listed at 4.6kg, which can be useful as a general reference when comparing to the removed unit. If the old alternator differs significantly in mounting style, pulley arrangement, or size, it is worth stopping and rechecking the application rather than forcing a near match. That approach is especially important on Delco style units where several physical variants can exist.

Warranty coverage is stated as 3 years for passenger vehicles and 1 year for commercial use. If the alternator is being fitted to a commercial vehicle, the warranty basis is different, so it is worth keeping the intended vehicle use in mind at the point of purchase and during installation records.

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 DXA481 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.
