Genuine Alternator 12V 140A Mitsubishi Style MXA2059

This Genuine Products alternator is a new 12V, 140A unit in Mitsubishi style, identified by part number MXA2059. It is built with an internal regulator, a 6 groove pulley, and a single leg alternator mount, so the physical mounting and belt drive details can be checked before purchase.

The listed measurements include a 58mm pulley outside diameter, 51mm mount leg thickness, 139mm mount centre to centre, and 10mm pivot and adjusting hole diameters. Those dimensions are the practical points to compare against the vehicle’s original alternator and brackets when confirming suitability.

It is supplied as a new rotating electrical component and carries a three year warranty. The unit weighs 6.14kg, which is a useful reference when comparing against the removed part or checking shipping and handling requirements.

Application and Buying Notes

The most important checks on this alternator are the part number MXA2059, the 12V system voltage, the 140A output, and the mounting details. With a single leg mount, 139mm mount centre to centre, and 10mm pivot and adjusting holes, it is worth comparing the removed unit closely rather than relying on appearance alone.

The pulley is a 6 groove type with a 58mm outside diameter. That matters because belt alignment and groove count must match the existing drive system. If the old alternator has a different pulley section, diameter, or mount spacing, the unit may not be suitable even if the vehicle appears similar.

Because the fitment information supplied includes multiple Holden and HSV applications, the safest approach is to match the listed application against the vehicle, then verify the actual alternator dimensions on the car. The supplied notes also identify Mitsubishi as the unit make, so the vehicle and the existing alternator should both be checked carefully before purchase.

This is a new alternator and the listed warranty is three years. That gives a useful reference point for buyers comparing repair options, but it does not replace fitment checking. Electrical output, regulator type, and mounting style all need to line up with the original unit for a proper 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 MXA2059 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.

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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using part number MXA2059, the 12V 140A specification, the single leg mount, and the 58mm 6 groove pulley details against the vehicle and the removed alternator before ordering.
