OEX Alternator 12V 70A Denso Style DXA431

The OEX Alternator DXA431 is a new 12V, 70A unit in Denso style, supplied as a single-leg alternator with an internal regulator. Key physical points for checking before purchase include a 54mm pulley outside diameter, 6 groove pulley section, 58mm mount leg thickness, 10mm pivot hole diameter and an M8 x 1.25 adjusting hole.

This alternator is listed for Denso applications and carries OEX part number DXA431. It weighs 5.3kg and is supplied each. Those details matter when comparing a replacement to the unit already fitted, especially where mounting style, pulley layout and connector arrangement need to match the vehicle’s charging system.

OEX states this product is sourced from original equipment manufacturers and aftermarket suppliers, with manufacturing from ISO9001 certified factories. It is backed by a 3 year warranty for passenger use and 1 year for commercial use, which gives clear ownership cover when the part is fitted to the correct application.

Application and Buying Notes

Before ordering, compare the fitted alternator against DXA431 and check the key physical points: 12V system voltage, 70A output, single-leg mounting, internal regulator, 6 groove pulley and 54mm pulley outside diameter. Those details are the practical checks that help separate a correct replacement from one that only looks similar in photographs.

The mount leg thickness of 58mm, pivot hole diameter of 10mm, adjusting hole diameter of M8 x 1.25 and mount centre to centre measurement of 163mm are especially useful when confirming bracket alignment. If any of those measurements differ from the alternator already in the vehicle, the part may not line up correctly even if the body shape appears close.

Because the unit is listed as Denso style and suits Denso applications, it is wise to verify the original unit make as well as the part number on the old alternator where possible. Electrical plugs, pulley offset and belt alignment are all worth checking during comparison, particularly on older Toyota Camry and Lexus ES applications where small production differences can affect compatibility.

The stated warranty is 3 years for passenger use and 1 year for commercial use. That cover applies to the listed product, but only once the alternator is fitted to the correct application and used within its intended duty. If the vehicle is used commercially, it is sensible to confirm the lower warranty term before purchase so there are no surprises later.

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 DXA431 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 70A Denso Style. Part number DXA431 should be checked first. Listed voltage is 12. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 DXA431, 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.

Available application references include LEXUS ES, LEXUS ES 1991, LEXUS ES 1992, LEXUS ES 1993, TOYOTA CAMRY, TOYOTA CAMRY 1988. 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: Confirm fitment by matching the part number DXA431, the Denso style application, and the listed mounting and pulley measurements against the vehicle and the removed alternator before ordering.
