OEX Alternator 12V 130A Denso Style DXA597

The OEX DXA597 is a new 12V alternator rated at 130A and built in Denso style, with a quad leg alternator mount and internal regulator. It is listed as a direct type replacement only where the unit match is confirmed by OE number and application details, so the part number and regulator plug configuration need to be checked before ordering.

Key physical details on this unit include 36mm inside mounting legs, an M10x1.25 / 11 pivot hole diameter, an M8x1.25 adjusting hole diameter, a 53mm pulley outside diameter, and a 7 groove pulley section. It also carries Mount Cnt to Cnt of 175mm, which is a useful checkpoint when comparing against the removed alternator.

The regulator note is important on this alternator. The offered option has an RLO terminal in the regulator plug, and DXA4006 is noted for units requiring an S terminal. ACX6250 may be required to confirm circuit configuration, so it is worth checking the plug and circuit arrangement on the vehicle before purchase.

Application and Buying Notes

Before buying, compare the removed alternator with the DXA597’s mounting and pulley details: 36mm inside mounting legs, M10x1.25 / 11 pivot hole, M8x1.25 adjusting hole, 53mm pulley outside diameter and a 7 groove pulley section. These measurements are the practical checks that help confirm the replacement will physically suit the vehicle.

The regulator configuration needs particular attention on this unit. The supplied note states the offered option has an RLO terminal in the regulator plug, while DXA4006 is used where an S terminal is required. If the vehicle’s circuit arrangement is uncertain, ACX6250 may be required to confirm the correct configuration before the alternator is fitted.

This alternator is rated at 130A, so it suits the electrical output level specified for the part, but output rating alone does not confirm fitment. The important identifiers to match are DXA597, Denso style, internal regulator, quad leg mount and the part’s OE/application details.

The product is new and backed by a 3yr Passenger / 1yr Commercial warranty. That warranty does not replace fitment checks, so it is still sensible to compare the alternator against the old unit, the plug style and the mounting points before purchase or installation.

If the vehicle uses a different terminal arrangement or a different mounting layout, the alternator may look similar but still be incorrect. For that reason, confirm the part number and the application information together rather than relying on the vehicle make alone.

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 DXA597 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA597, Brand OEX, Description OEX Alternator 12V 130A Denso Style - Confirm by OE number - see note, Adjusting Hole Diameter M8x1.25, Pin Code IR116, Power Rating (Amp) 130, Pulley Section 7 Groove, Suits Unit Make Denso.

OEX Alternator 12V 130A Denso Style - Confirm by OE number - see note. Part number DXA597 should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA597, 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.

Compatibility note: Please confirm fitment using part number DXA597, the Denso style application details, the regulator plug type, and the mounting and pulley measurements before ordering.
