OEX Alternator 12V 130A Denso Style DXA598

The OEX Alternator DXA598 is a 12V, 130A alternator built in a Denso style configuration. It is a new unit, supplied each, with a 6 groove pulley, internal regulator, and a twin leg alternator mount. Key dimensions include 164mm mount centre to centre, 43mm inside mounting legs, a pivot hole diameter of M10x1.25 / 11, and an adjusting hole diameter of M8x1.25.

This alternator is listed for Denso applications and carries part number DXA598 with pin code IR115. The unit weighs 6.08kg and has a pulley outside diameter of 57mm. Those details matter when matching the replacement to the vehicle’s original alternator and bracket arrangement, especially where mounting style and pulley layout need to line up exactly.

OEX states its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. For buyers, the practical point is simple: confirm the electrical rating, mounting dimensions, and Denso-style application before ordering, because alternators must match the vehicle setup closely to install and function correctly.

Application and Buying Notes

Before ordering, compare the vehicle’s original alternator against the key identifiers on this unit: part number DXA598, Denso style application, 12V voltage, 130A output, and the twin leg mount layout. Alternators that look similar can still differ in pulley section, mounting leg spacing, or regulator type, so those details need to match the existing setup.

The mounting measurements are especially important on this unit. The inside mounting legs are 43mm, the mount centre to centre is 164mm, the pivot hole diameter is M10x1.25 / 11, and the adjusting hole diameter is M8x1.25. If any of these points differ from the vehicle’s original unit, fitment may not be correct even where the vehicle appears in the application list.

The pulley arrangement should also be checked carefully. This alternator uses a 6 groove pulley with a 57mm outside diameter. That needs to suit the belt system already on the vehicle. Matching the pulley section is a basic but essential step, because the wrong belt profile can prevent proper installation or correct belt tracking.

This is a new OEX alternator rather than a remanufactured unit, and it carries an internal regulator. Those details are useful when the original part is being replaced as a complete assembly. If the vehicle uses a different regulation setup or a non-Denso variant, confirm the original part details first so the replacement is selected correctly.

The warranty listed is 3 years for passenger use and 1 year for commercial use. Warranty terms do not replace the need to confirm fitment, but they do provide a clear reference for how the unit is supported after purchase. Keep the invoice and part details together with the vehicle information for easier reference if needed.

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 DXA598 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.

For part number DXA598, 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: Confirm fitment by checking the vehicle application details, the original alternator part number, and the key measurements on this OEX DXA598 unit before ordering. If the mounting, pulley, regulator type, or Denso-style application does not match the vehicle, do not assume compatibility.
