Mahle Alternator 12V 100A VG308

The MAHLE Alternator VG308 is a new 12V, 100A unit supplied as an each item for rotating electrical applications. It is listed as an OE product and uses an internal regulator, which makes the electrical specification straightforward to match against the original charging setup before ordering.

Key mounting details are provided for identification and comparison: twin leg alternator mount, 149mm mount centre to centre, 82mm inside mounting legs, 8mm pivot hole diameter and M8 adjusting hole diameter. The pulley is AA section with a 73mm outside diameter, so the belt profile and pulley size should be checked carefully against the vehicle already fitted.

This alternator is identified with part number VG308 and the MAHLE brand. It is a 12 volt, 100 amp replacement option with a stated weight of 5.92kg and a one year warranty. Those details are useful when confirming whether the replacement should be matched by part number, mounting style and electrical output rather than by appearance alone.

Application and Buying Notes

Before ordering, confirm the vehicle uses a 12V charging system and compare the existing alternator against part number VG308. The mounting arrangement matters here: this unit has a twin leg mount, 149mm centre to centre, 82mm inside mounting legs, an 8mm pivot hole and an M8 adjusting hole. If those points do not line up with the original part, it should not be treated as a direct match.

The pulley details are equally important. This alternator uses an AA section pulley with a 73mm outside diameter, so belt type and pulley size need to be checked against the existing installation. Even where the electrical rating is correct, the belt profile must suit the vehicle’s drive system to avoid fitment issues.

The 100A output is the key electrical figure for this unit. If the original alternator is a different amperage, it is worth confirming whether the charging system, regulator arrangement and connector setup are intended to suit a 100A replacement. The internal regulator also needs to align with the vehicle’s original charging control arrangement.

As a new MAHLE OE product, this alternator is intended for buyers who want a replacement identified by specification rather than by guesswork. Matching the brand, part number, mount type and dimensions is the safest approach when purchasing rotating electrical parts, especially where the existing unit has been removed from the vehicle or the old label is no longer readable.

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 VG308 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.

Mahle Alternator 12V 100A. Part number VG308 should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number VG308, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

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: Please confirm fitment by checking the part number VG308, the 12V 100A specification, twin leg mount dimensions, pulley section and the vehicle’s original alternator details before purchase.
