OEX Alternator 12V 150A Denso Style DXA4157

The OEX Alternator 12V 150A Denso Style is a new 12-volt alternator with a 150 amp power rating, pad mounting, and an internal regulator. It is identified by Part No. DXA4157 and is listed as a Denso style unit, with a 5 groove pulley and a pulley outside diameter of 55mm.

This alternator suits Denso unit applications and carries a mount centre-to-centre measurement of 162mm, a mount leg thickness of 33mm, and both pivot hole and adjusting hole diameters of 8mm. Those dimensions are important when checking physical interchange, especially where the original unit must align correctly with the bracket and belt drive.

OEX states the product is sourced from market leading original equipment manufacturers and aftermarket suppliers, with manufacturing from ISO9001 certified factories to support engineering, testing, and quality control procedures. The unit is backed by a 3 year passenger / 1 year commercial warranty, and the alternator weighs 6kg.

Application and Buying Notes

Before ordering, compare the part number DXA4157, the Denso style designation, and the 12V 150A rating against the unit you are replacing. The alternator uses a pad mount, internal regulator, and a 5 groove pulley with a 55mm outside diameter, so the mounting style and belt alignment need to match the vehicle arrangement exactly.

The physical dimensions matter as much as the electrical output. Check the 162mm mount centre-to-centre measurement, 33mm mount leg thickness, and the 8mm pivot and adjusting hole diameters before you buy. If the brackets, fasteners, or pulley configuration differ from the original unit, the alternator may not line up correctly even if the application name looks familiar.

This alternator is listed as suitable for Denso unit make applications and the fitment data supplied includes Ford Focus and several Volvo models including C30, C70, S40, S60, S80, V50, V70 and XC90. Use those application details as a guide only and confirm the exact match on the vehicle by part number, mount style, pulley section, and regulator type.

OEX describes the unit as new and backed by a 3 year passenger / 1 year commercial warranty. That warranty coverage is useful, but it does not replace the need to verify the alternator specification against the existing unit before installation. For electrical components, matching the regulator type, output rating, and pulley arrangement is a sensible part of the buying process.

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 DXA4157 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 DXA4157 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 Pad. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4157, 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.

Compatibility note: Confirm fitment by matching Part No. DXA4157, Denso style application details, 12V 150A output, pad mount, internal regulator, and 5 groove pulley configuration against the original alternator and vehicle requirements before ordering.
