OEX Alternator 12V 150A Denso Style DXA4074

The OEX Alternator DXA4074 is a new 12V, 150A unit built in a Denso style format for vehicles that use a Denso alternator with a quad leg mount. It is supplied with an internal regulator, a 6 groove pulley, and a clutch style pulley fitted, so the mounting style and pulley arrangement should be checked carefully before purchase.

This alternator has inside mounting legs of 45mm, a mount centre to centre measurement of 139mm, and M10 x 1.5 pivot and adjusting hole diameters. Those measurements matter just as much as the 12V and 150A rating, because alternators that look similar can differ in bracket spacing, hole size, or pulley setup.

OEX lists this unit as part no. DXA4074 and pin code IR210, with a weight of 5.9kg. It is a new alternator, sold each, and carries a 3 year passenger / 1 year commercial warranty, which gives buyers a clear reference point when comparing replacement options for Denso-style applications.

Application and Buying Notes

Before ordering, match the part number DXA4074 and confirm the alternator mounting arrangement on the vehicle. This unit is a Denso style alternator with a quad leg mount, 45mm inside mounting legs, and 139mm mount centre to centre, so it should only be selected where those dimensions and the application line up.

The pulley setup is also important on this unit. It has a 54mm outside diameter pulley, a 6 groove pulley section, and a clutch style pulley fitted. If the replacement alternator does not match the pulley type or belt configuration already on the vehicle, the part may not be suitable even when the electrical rating is correct.

Electrical output is another key check. This alternator is rated at 12V and 150A with an internal regulator, so it suits applications designed for that charging setup. If the original unit differs in voltage, amperage, regulator type, or pin code, the safest approach is to compare the existing alternator details directly before purchase.

The listed fitment preview includes Ford Focus and a number of Volvo models, including C30, S40, S60, V40, V50, V60, XC60 and XC90. Use that only as a guide to the application families provided, and still verify the physical mount, pulley, and electrical details against the vehicle currently being serviced.

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 DXA4074 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 DXA4074, 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 FORD FOCUS, FORD FOCUS 2007, FORD FOCUS 2008, FORD FOCUS 2009, VOLVO C30, VOLVO C30 2006. 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 DXA4074 and checking the vehicle’s alternator mount, pulley type, voltage, amperage, regulator type, and hole spacing before ordering. Application details should be verified against the existing unit on the vehicle.
