OEX Alternator 12V 150A Denso Style DXA4136

This OEX alternator is a 12V, 150A unit with a Denso style layout and part number DXA4136. It is supplied new, carries an internal regulator, and uses a 6 groove pulley, so it is important to compare the physical mounting details as well as the electrical rating before ordering.

The mounting and fitment dimensions recorded for this alternator include a 149mm centre-to-centre mount, 60mm inside mounting legs, and M10x1.25 / 11 pivot and adjusting holes. The alternator mount is listed as quad leg, and the unit is specified with a 54mm pulley outside diameter.

This unit is listed as suitable for Denso applications and the fitment preview provided includes Lexus NX applications across 2014, 2015, 2016 and 2017. Even where the vehicle model is known, alternator matching still comes down to the part number, mounting pattern, pulley type and charge rating, so those details should be checked carefully before purchase.

Application and Buying Notes

Before ordering, match the part number DXA4136 against the alternator already fitted to the vehicle or the required replacement number. The listed fitment preview includes Lexus NX applications, but alternators are commonly defined by mounting pattern, pulley setup, regulator type and output rating, so the vehicle badge alone is not enough to confirm the correct unit.

The 150A output and internal regulator make this a specific charging system component rather than a universal alternator. Check that the vehicle needs a 12V alternator with a 6 groove pulley, quad leg mount, 149mm centre-to-centre mounting, and M10x1.25 / 11 pivot and adjusting holes before you commit to the purchase.

The unit weighs 5.96kg and uses a 54mm pulley outside diameter, both of which are useful physical checks when comparing against the existing alternator. If the old unit has a different mounting leg arrangement, pulley section, or hole size, it may not suit even if the vehicle family appears similar.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. For commercial vehicles in particular, confirming the exact application details matters because alternators are often changed previously, and a later replacement may not match the original factory configuration.

For the cleanest result, compare the alternator mounting ears, pulley groove count, electrical output requirement and the OEM replacement reference from the vehicle or the removed unit. If any of those details differ from what is listed here, pause and verify before ordering.

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 DXA4136 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 150A Denso Style. Part number DXA4136 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad 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 DXA4136, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LEXUS NX, LEXUS NX 2014, LEXUS NX 2015, LEXUS NX 2016. 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: Confirm fitment using part number DXA4136 together with the listed 12V, 150A Denso style application details, 6 groove pulley, quad leg mount, 149mm centre-to-centre measurement and M10x1.25 / 11 hole sizes before purchase.
