The Genuine Products Alternator 12V 140A Delco Style is a new rotating electrical unit with part number DXA493 and a 12 volt, 140 amp output. It is listed with a Delco suitment style, internal regulator, and a 6 groove pulley, making the core matching points easy to check before ordering.
This alternator is supplied as a new unit, not remanufactured, and carries a one year warranty. The mounting details are specific: single leg alternator mount, 51 mm mount leg thickness, 139 mm mount centre to centre, and a 10 mm pivot hole diameter. Those measurements matter when comparing against the unit already fitted to the vehicle.
The unit is described as a Genuine Products alternator, with a stated weight of 6.48 kg and a pulley outside diameter of 56 mm. If you are replacing an existing alternator, the part number DXA493, voltage, amperage, pulley section, and mount style should be checked together rather than relying on one detail alone.

Application and Buying Notes
Before buying, compare the replacement unit against the part number DXA493 and the physical details on your existing alternator. The important checks here are 12V, 140A, Delco style, internal regulator, 6 groove pulley, single leg mount, 51 mm mount leg thickness, 139 mm mount centre to centre, and 10 mm pivot hole diameter.
The pulley and mounting measurements are especially important because alternators that appear similar can differ in pulley section, offset, or bracket arrangement. A 56 mm pulley outside diameter and 6 groove section should be confirmed against the vehicles belt setup and the alternator already removed from the engine.
This unit is listed as a new alternator and weighs 6.48 kg, so it is intended as a direct replacement item rather than a rebuilt core exchange style part. If your vehicle uses the Delco style unit shown in the application notes, the safest approach is to match the listed vehicle application, part number, and dimensions together before ordering.
If you are cross-checking against a current part, use the regulator type, mounting layout, and pin code IR193 as additional reference points. Those details help reduce the chance of ordering a unit that is electrically similar but physically different at the bracket or connector end.
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 DXA493 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.

Genuine Alternator 12V 140A Delco Style. Part number DXA493 should be checked first. Listed voltage is 12. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.
Mount style is Single 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 DXA493, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
Available application references include HOLDEN COLORADO, HOLDEN COLORADO 2012, HOLDEN COLORADO 2013, HOLDEN COLORADO 2014, HSV SPORTSCAT, HSV SPORTSCAT 2018. 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 One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.
Compatibility note: Confirm compatibility by matching part number DXA493, 12V 140A output, Delco style suitment, internal regulator, 6 groove pulley, and the listed mount dimensions against the alternator currently fitted to the vehicle.
