OEX Alternator 12V 90A Denso Style DXA596

The OEX Alternator DXA596 is a 12V, 90A unit built in Denso style and supplied as a new alternator. It uses an internal regulator, a 7 groove pulley with 54mm outside diameter, and a twin leg alternator mount, so the mounting style and drive setup are important checks before ordering.

This unit suits Denso applications and carries inside mounting legs of 45mm, a pivot hole diameter of M10x1.25 / 11, an adjusting hole diameter of 11, and a mount centre to centre measurement of 167mm. Those dimensions are the key reference points when comparing the alternator to the vehicle already fitted.

OEX positions this alternator in its rotating electrical range and lists it with a 3yr passenger / 1yr commercial warranty. It is a practical replacement option where the existing alternator matches the part number DXA596, the Denso-style layout, and the stated mounting and pulley specifications.

Application and Buying Notes

Check the part number first. DXA596 is the clearest match point for this alternator, followed by the physical details: 12V, 90A, internal regulator, twin leg mount, 7 groove pulley, 54mm pulley diameter, and the 167mm mount centre to centre measurement. If any of those differ from the unit already in the vehicle, re-check before fitting.

The mounting dimensions are just as important as the electrical rating. This alternator has inside mounting legs of 45mm, a pivot hole diameter of M10x1.25 / 11, and an adjusting hole diameter of 11. Those measurements need to line up with the bracket and adjuster arrangement on the vehicle, otherwise the unit may not install correctly even if the part number looks close.

Because this is listed as Denso style and suits Denso unit make, it should be matched carefully to the existing alternator type rather than assumed to be universal. The fitment list supplied includes Toyota, Hiace, Hiace / Commuter, Hilux, Land Cruiser Prado, and Regius Ace applications, but the safest purchase method is still to compare the part number, pulley grooves, regulator type, and all mounting dimensions against the current unit.

The warranty listed is 3 years for passenger use and 1 year for commercial use. That gives a useful reference for intended usage, but it does not replace a proper fitment check. Commercial use can place different demands on charging system components, so confirm the application, drive type, and mounting arrangement before ordering.

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 DXA596 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 45mm, Pivot Hole Diameter M10x1.25 / 11, Pulley Outside Diameter 54mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 167mm, Weight 4.24kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA596, Brand OEX, Description OEX Alternator 12V 90A Denso Style, Adjusting Hole Diameter 11, Pin Code IR115, Power Rating (Amp) 90, Pulley Section 7 Groove, Suits Unit Make Denso, Alternator Mount Twin Leg.

OEX Alternator 12V 90A Denso Style. Part number DXA596 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 DXA596, 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 TOYOTA HIACE, TOYOTA HIACE / COMMUTER, TOYOTA HIACE / COMMUTER 2005, TOYOTA HIACE / COMMUTER 2006. 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 part number DXA596, Denso style application details, 12V 90A output, internal regulator, 7 groove pulley, and the mounting measurements before purchase. Use the vehicle application only as a guide and verify the alternator fitted to the vehicle wherever possible.
