Application and Buying Notes

When comparing this Valeo alternator to a removed unit, the most important checks are part number 439732, OEM number FG18S060, and the mounting pattern. The key mounting measurements supplied are 75mm inside mounting legs, 126mm centre-to-centre, and a twin leg, three-point mounting setup, so these dimensions should be matched carefully to the original alternator or bracket arrangement.

The electrical specification is just as important as the physical fit. This alternator is rated at 12V and 180A, with an internal regulator. If the vehicle or application expects a different voltage, charge current, or regulator arrangement, it should not be assumed to interchange without verification.

Pulley configuration is another area that needs close attention. This unit has a 55mm pulley outside diameter and a 6 groove pulley section, so belt alignment and groove count need to match the existing drive setup. The connector detail is also specific: no connector for revolution counter is listed, which means the plug and monitoring arrangement on the vehicle should be checked before purchase.

Valeo is identified as the brand and suits unit make, and the unit is new rather than remanufactured. For buyers replacing a worn alternator, the weight of 7.55kg can also be a useful comparison point against the removed part when confirming the correct unit has been selected.

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 439732 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.
