Application and Buying Notes

The safest way to confirm the correct alternator is to match the part number 13520817, the 12V system voltage, and the 150A output against the unit already on the vehicle. The listing also notes a Denso unit make, pad mount arrangement, IR112 pin code, and a 5 groove pulley, so those points should be compared carefully before purchase.

Pulley size and mounting details are often the deciding factors in alternator replacement. Here, the pulley outside diameter is 54mm and the mount leg thickness is 79mm. If either of those measurements differs from the existing unit, the part may not interchange correctly even if the general alternator type looks similar.

Because this is a new OE product, it is intended as a direct replacement where the vehicle application matches. The one year warranty applies to the part as supplied, but it does not remove the need to verify the charging system layout, pulley section, and connector style on the vehicle first.

If the vehicle is a Holden Commodore variant, use the application details as a check point rather than relying on the model name alone. Alternators can vary by build date, engine, and electrical configuration, so the safest confirmation remains the combination of part number, voltage, amperage, mount type, and pin code.

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 13520817 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.
