OEX Alternator 12V 70A Denso Style DXA4036

The OEX Alternator 12V 70A Denso Style, part number DXA4036, is a new rotating electrical unit supplied as a single alternator assembly. It is a 12 volt, 70 amp unit with an internal regulator, so it is intended to suit applications that match those electrical and mounting requirements rather than being a universal fit.

This alternator is listed with a Denso-style specification and suits Denso unit make applications. Key mounting details include a single leg alternator mount, 58 mm mount leg thickness, 165 mm mount centre-to-centre, 10 mm pivot hole diameter and 8 mm adjusting hole diameter. Those measurements matter when checking the physical fit against the original unit.

The pulley is a 6 groove design with a 55 mm outside diameter, and the unit weighs 4.98 kg. If you are replacing an alternator, it is worth confirming the regulator type, pulley style, and mounting dimensions before ordering, as those points are just as important as the electrical rating on a 12 volt 70 amp unit.

Application and Buying Notes

Before ordering, compare the part number DXA4036 with the alternator you are replacing, then check the mounting pattern and electrical specification. This unit is 12V and 70A, uses an internal regulator, and has a single leg mount with a 58 mm mount leg thickness, 165 mm mount centre-to-centre, 10 mm pivot hole and 8 mm adjusting hole.

The pulley detail also needs attention. This alternator is fitted with a 6 groove pulley measuring 55 mm outside diameter, so the belt type and pulley arrangement on the vehicle should match. A Denso-style alternator can still vary by application, so the shape and dimensions should be checked against the original part rather than relying on appearance alone.

If you are replacing a failed alternator, confirm whether the vehicle uses an internal regulator configuration and whether the original unit matches the listed mount and pulley measurements. The unit weighs 4.98 kg and is supplied new, which may help when comparing it with a worn or remanufactured replacement already on the vehicle.

The warranty listed is 3 years for passenger vehicles and 1 year for commercial use. Warranty terms are useful, but they do not replace fitment checks. The safest approach is to confirm the vehicle application, the Denso unit make match, and the physical measurements before fitting or committing to purchase.

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 DXA4036 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 DXA4036 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 DXA4036, 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 TOYOTA ESTIMA EMINA / LUCIDA, TOYOTA ESTIMA EMINA / LUCIDA 1990, TOYOTA ESTIMA EMINA / LUCIDA 1991, TOYOTA ESTIMA EMINA / LUCIDA 1992. 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: Please confirm fitment by matching part number DXA4036, Denso-style application details, and the listed mounting and pulley measurements with the original alternator before ordering.
