OEX Alternator 12V 115A Mitsubishi Style MXA369

The OEX Alternator MXA369 is a 12V, 115A rotating electrical unit in Mitsubishi style, supplied new as an each item for replacement work where the original alternator specifications need to be matched closely. It uses an internal regulator, a twin leg alternator mount, and a 4 groove pulley, so those points should be checked against the vehicle before purchase.

Key identifying measurements include 66mm inside mounting legs, 166mm mount centre to centre, a 10mm pivot hole diameter, and an M8 x 1.25 adjusting hole. The pulley outside diameter is 64mm, and the unit weighs 4.8kg, which are useful checks when comparing against the original alternator.

This alternator is listed for Mitsubishi applications and carries part number MXA369 with pin code IR70. For buyers replacing a worn charging unit, matching the part number and the mounting and pulley details is the safest way to avoid problems at installation.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. The unit is backed by a 3 year passenger and 1 year commercial warranty, which gives a clear warranty basis for different vehicle use cases.

Application and Buying Notes

Before ordering, compare MXA369 with the alternator already fitted to the vehicle and check the Mitsubishi style case, twin leg mount, and 4 groove pulley. The listed mounting measurements are 66mm inside mounting legs and 166mm centre to centre, so those dimensions should line up with the original unit.

The electrical side matters just as much as the physical fit. This alternator is 12V with a 115A output and an internal regulator, so the vehicle’s charging system needs to suit those details. If the existing unit uses a different voltage, amp rating, or regulator arrangement, this part may not be the correct replacement.

Pulley and hole sizes are common installation checkpoints that can save time and reduce returns. The pulley outside diameter is 64mm, the pivot hole diameter is 10mm, and the adjusting hole is M8 x 1.25. If any of those points differ from the old alternator, confirm the application before fitting.

The stated fitment coverage includes Mitsubishi FTO, Mitsubishi Lancer, Mitsubishi Pajero IO, and Subaru Outback applications, but that does not remove the need to verify the exact vehicle match. Model names can share similar charging components across different years and variants, so the safest check is the part number MXA369 together with the mounting and pulley details.

For buyers using the warranty as part of their decision, the alternator is covered for 3 years in passenger use and 1 year in commercial use. That warranty does not replace the need to confirm fitment, especially where the mounting legs, regulator type, or pulley section may differ from the existing alternator.

If the vehicle has been modified, had a previous alternator change, or uses different accessories or belt drive arrangements, measure the existing unit before purchase. The 4 groove pulley, 64mm pulley outside diameter, and 4.8kg weight provide practical reference points when checking whether this OEX unit is the correct replacement.

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 MXA369 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.
