OEX Alternator 12V 90A Denso Style DXA4069

The OEX Alternator DXA4069 is a new 12V, 90A unit built in a Denso style layout for vehicles that use a Denso alternator with a twin leg mount. It is supplied as an alternator each, with an internal regulator, a 7 groove pulley, and an 83mm inside mounting leg spacing.

Key dimensions on this unit include a 160mm mount centre-to-centre, a 10mm pivot hole diameter, and an M8x1.25 adjusting hole. Those mounting and pulley details are important when checking that the replacement matches the original unit already fitted to the vehicle.

This alternator is listed as fitting certain Holden and Isuzu applications, including Holden Colorado, Holden Rodeo, and Isuzu D-Max variants. Because alternators can vary by engine, charging system, and bracket style, the part number DXA4069 and the physical measurements should be checked carefully before purchase.

Application and Buying Notes

When replacing an alternator, the safest check is to match the part number DXA4069, the Denso style layout, and the mounting pattern before ordering. This unit uses a twin leg mount with 83mm inside mounting legs, a 160mm mount centre-to-centre, a 10mm pivot hole, and an M8x1.25 adjusting hole, so those dimensions should be compared against the original unit already in the vehicle.

The electrical rating is 12V at 90A, which suits vehicles that require that charging specification. The regulator is internal, and the pulley is a 7 groove type with a 62mm outside diameter. If the original alternator differs in pulley section, mounting style, or regulator arrangement, the replacement may not be a direct match even if the vehicle make appears in the fitment list.

This alternator is a new OEX unit and is backed by a 3 year passenger or 1 year commercial warranty. That warranty period does not remove the need to verify the application details first, especially on Holden Colorado, Holden Rodeo, and Isuzu D-Max vehicles where alternator brackets and charging equipment can vary by build.

If you are unsure, compare the old alternator, the vehicle details, and the physical measurements listed here side by side. A careful check of the mounting legs, pulley configuration, voltage, and output rating helps avoid ordering the wrong unit and saves time at installation.

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 DXA4069 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 1 ROTATING ELECTRICAL, Part No. DXA4069, Brand OEX, Description OEX Alternator 12V 90A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR97, Power Rating (Amp) 90, Pulley Section 7 Groove, Suits Unit Make Denso, Alternator Mount Twin Leg.

OEX Alternator 12V 90A Denso Style. Part number DXA4069 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin 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 DXA4069, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN COLORADO, HOLDEN COLORADO 2008, HOLDEN COLORADO 2009, HOLDEN COLORADO 2010, ISUZU D-MAX, ISUZU D-MAX 2007. 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 with the part number DXA4069, the Denso style twin leg mount, and the stated measurements before purchase. Vehicle listing alone is not enough to confirm the correct alternator for every application.
