OEX Alternator 12V 120A Mitsubishi Style MXA358

The OEX Alternator MXA358 is a new 12V, 120A rotating electrical unit built in Mitsubishi style and supplied with an internal regulator. It is listed as a 5 groove pulley alternator with a pulley outside diameter of 64mm, making it important to match the physical layout and belt arrangement before ordering.

This unit is specified with a quad leg alternator mount, 48mm inside mounting legs, a 177mm mounting centre to centre measurement, and M10x1.25 pivot and adjusting hole diameters. Those mounting dimensions are the key checks for applications where the alternator position and bracket spacing must line up correctly.

OEX identifies this alternator as suit unit make Mando, and the part number is MXA358. It weighs 6.34kg and is supplied as each, so buyers comparing a replacement should use the part number, mount style, regulator type, pulley section, and voltage together rather than relying on appearance alone.

Application and Buying Notes

Before buying, compare the part number MXA358 against the unit being replaced and check the alternator mount details carefully. This alternator is a 12V, 120A Mitsubishi style unit with an internal regulator, so the electrical setup and mounting style need to match the vehicle’s existing arrangement.

The mounting details matter just as much as the output rating. This unit has a quad leg mount, 48mm inside mounting legs, a 177mm centre to centre measurement, and M10x1.25 pivot and adjusting holes. If any of those dimensions differ from the old alternator or the bracket on the vehicle, the part may not line up correctly.

Pulley match is another important checkpoint. The pulley is a 5 groove design with a 64mm outside diameter, so the belt profile and pulley diameter should be checked against the existing unit. Even when a vehicle is listed in the fitment references, the safest approach is to confirm the old alternator’s specification and mount pattern before purchase.

The unit is listed as suit unit make Mando, which is useful where the original alternator follows that style. Weight is 6.34kg, which can help with comparison against a removed part, but the main checks should still be voltage, amp output, regulator type, mount type, and the MXA358 part number.

Warranty coverage is listed as 3yr Passenger and 1yr Commercial. That makes it suitable for buyers wanting a new replacement alternator with stated support terms, but warranty does not replace the need to confirm fitment and installation details for the specific vehicle and charging system.

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 MXA358 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 MXA358, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI SANTA FE, HYUNDAI SANTA FE 2007, HYUNDAI SANTA FE 2008, HYUNDAI SANTA FE 2009, KIA SORENTO, KIA SORENTO 2002. 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.

Compatibility note: Confirm fitment with part number MXA358, the 12V 120A specification, quad leg mount, 5 groove pulley, and the mounting dimensions before ordering. Vehicle references include HYUNDAI Santa Fe, HYUNDAI Terracan, HYUNDAI Tiburon, and KIA Sorento, but final compatibility should always be checked against the removed unit and application details.
