OEX Alternator 12V 115A Denso Style DXA4016

The OEX Alternator 12V 115A Denso Style, part number DXA4016, is a new alternator built for 12 volt charging systems and rated at 115 amps. It is specified with a Denso-style unit make, a single leg alternator mount, and an internal regulator, so it is important to check the original unit details before ordering.

This alternator uses a 6 groove pulley with a 59mm outside diameter and a 10mm adjusting hole diameter. It weighs 4.5kg and is sold as each, which makes it straightforward to compare against the removed unit when checking pulley layout, mounting arrangement, and physical size.

OEX lists this product as part of its rotating electrical range, with sourcing from market leading original equipment manufacturers and aftermarket suppliers, and from ISO certified factories. It is backed by a 3 year passenger and 1 year commercial warranty, which gives a clear warranty framework depending on how the vehicle is used.

Application and Buying Notes

Before ordering, compare the part number DXA4016, the Denso style unit make, and the single leg alternator mount with the alternator currently fitted to the vehicle. Those three details are the most useful starting points for avoiding a mismatch, especially where the vehicle has had prior repairs or a replacement charging unit fitted.

The 12V, 115A output rating matters because alternators are selected to suit the vehicle’s electrical demand and charging system design. The 6 groove pulley, 59mm pulley outside diameter, and 10mm adjusting hole diameter should also be checked carefully, as pulley and mount differences can stop a unit from lining up correctly even when the vehicle model looks similar on paper.

This alternator is listed as new and carries a 3 year passenger warranty or 1 year commercial warranty. Warranty terms are useful, but they do not replace fitment confirmation. The safest approach is to match the part number, mounting style, pulley setup, and regulator type against the removed unit before fitting.

For Land Rover Freelander applications, the year grouping provided runs from 2000 through 2006. That is helpful as a guide, but alternator fitment can still vary by build date, charging system configuration, and previous repair history. A careful visual comparison and part number check is still the best way to confirm suitability.

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 DXA4016 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 DXA4016, 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 115 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include LAND ROVER FREELANDER, LAND ROVER FREELANDER 2000, LAND ROVER FREELANDER 2001, LAND ROVER FREELANDER 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.

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 compatibility using part number DXA4016, the Denso style specification, the single leg mount, and the 6 groove pulley details before purchase. If the original alternator differs in mounting, pulley, regulator type, or output rating, do not rely on model name alone.
