OEX Alternator 12V 70A Denso Style Remanufactured DXA453

The OEX Alternator DXA453 is a 12V, 70A unit built in a Denso style configuration and supplied as a remanufactured alternator. It uses an internal regulator and a 5 groove pulley, with a pulley outside diameter of 66mm, so it is important to compare those details with the unit being replaced before ordering.

This alternator is listed with a single leg mount, 57mm mount leg thickness, 153mm mount centre to centre, a 10mm pivot hole diameter and an M12x1.5 adjusting hole diameter. Those mounting and connection dimensions are the practical checkpoints that usually matter most when matching a replacement alternator to an existing application.

OEX positions this unit within its rotating electrical range and states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers. The alternator is covered by a 3 year passenger / 1 year commercial warranty, which gives a clear guide to the intended use profile while still leaving fitment to the buyer to confirm against the part number and physical dimensions.

Application and Buying Notes

When replacing an alternator, the safest check is to match the part number DXA453 and then confirm the physical details against the removed unit. The key points here are 12V output, 70A rating, internal regulator, Denso style, single leg mount and a 5 groove pulley with a 66mm outside diameter.

Mounting dimensions matter as much as electrical rating. This unit has a 57mm mount leg thickness, 153mm mount centre to centre, a 10mm pivot hole diameter and an M12x1.5 adjusting hole diameter, so any variation in bracket design, pulley alignment or adjustment slot position should be checked before purchase.

The supplied fitment references cover several Audi A3, Honda Accord and Volvo 940 applications, but they are not a substitute for confirming the exact vehicle build and the alternator currently fitted. If the original unit is missing, compare the mounting style, pulley groove count and regulator arrangement carefully, because a Denso style alternator can still vary in details between applications.

This alternator is remanufactured rather than new, so it is intended as a service replacement unit. The stated weight is 4.94kg, which may help when comparing units in hand, and the warranty of 3 years passenger or 1 year commercial provides a useful reference for how the product is supported when used in the appropriate application.

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 DXA453 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 DXA453, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using the part number DXA453, the Denso style configuration, and the full mounting and pulley details before ordering. Vehicle listings should be treated as a guide only, and the final match should be checked against the unit being replaced.
