OEX Alternator 12V 100A Denso Style DXA4187

The OEX Alternator DXA4187 is a 12V, 100A passenger alternator listed in Denso style. It sits in the rotating electrical category and is sold as an each unit, which makes it suitable when replacing a single alternator rather than buying in a kit.

This unit is identified as part number DXA4187 and the product description reads OEX Alternator 12V 100A Denso Style. That combination of voltage, output and style is the key information to check against the vehicle application before ordering, especially where the original alternator shape, plug arrangement or mounting arrangement must match.

OEX states its brand is sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with products sourced from ISO9001 certified factories. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives the buyer a clear reference point for the intended application and product support.

Application and Buying Notes

When buying an alternator, the safest match is the part number and application details, not just the vehicle badge. For this unit, DXA4187 and the 12V 100A Denso style description are the main identifiers to confirm before purchase. If the original alternator is being replaced, compare the casing style, mounting points, plug connection and pulley arrangement against the vehicle’s existing unit.

The 100A output is an important electrical detail because alternator capacity needs to suit the vehicle’s charging system and electrical load. A 12V alternator is standard for many passenger vehicles, but the physical fit still has to line up correctly. The supplied fitment preview shows JEEP Cherokee applications across 2002 to 2008, so it is sensible to verify the exact model year and factory configuration before committing to the order.

This alternator is listed as an OEX passenger unit and carries a 3 year passenger warranty, with 1 year warranty for commercial use. That difference matters if the vehicle is used in a work setting or runs higher duty cycles. If you are replacing an alternator that has failed, it is also worth checking the battery condition, wiring, belt condition and charging circuit, because those items can affect the lifespan of a new alternator even when the replacement part is correct.

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 DXA4187 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 DXA4187, 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 passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include JEEP CHEROKEE, JEEP CHEROKEE 2002, JEEP CHEROKEE 2003, JEEP CHEROKEE 2004. 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: Please confirm compatibility by matching part number DXA4187 and checking the vehicle’s application details, mounting style and electrical connection before ordering.
