Valeo Alternator 12V 90A 5 Groove Pad Mount Part No. 439232

The Valeo Alternator 12V 90A, part no. 439232, is a new alternator supplied as each unit with a 12 volt electrical system and a 90 amp charge current. It uses an internal regulator, a pad mount, and direct fastening, which are important checks when replacing a matching rotating electrical unit.

This alternator has a 51mm pulley outside diameter with a 5 groove pulley section, and it weighs 5.5kg. Those details matter when comparing the physical layout of the belt drive and the mounting arrangement against the vehicle already fitted.

Valeo is listed here as the brand and as the unit make, with a note that it is a leading OE manufacturer and supplier for many euro vehicles. The alternator is identified as new rather than remanufactured, and the warranty is one year.

A connector is noted as no connector for revolution counter, so the electrical connection style should be checked carefully before purchase. If you are replacing an existing Valeo alternator, part number 439232 is the clearest identifier to confirm alongside the voltage, amperage, and pulley details.

Application and Buying Notes

The most reliable way to confirm this Valeo alternator is by matching part number 439232 to the unit already fitted. The listed specifications also need to line up, especially the 12V system, 90A charge current, internal regulator, pad mount, and direct fastening arrangement.

The pulley details are specific: a 51mm outside diameter with a 5 groove pulley section. If the belt drive on the vehicle does not match those details, the alternator may not be suitable even if the brand name is the same.

The connector detail is also worth checking closely. This alternator is listed with no connector for revolution counter, so any vehicle that requires a different warning or counter connection needs to be verified before purchase.

Because fitment information is limited to the supplied Mercedes-Benz and Mercedes-Benz A-Class applications, the safest approach is to compare the replacement unit side by side with the original. Pay attention to mounting points, pulley alignment, and the electrical plug arrangement as part of the identification process.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles, which gives useful context, but it does not replace a vehicle-specific check. The one year warranty covers the product as supplied, so it is still best practice to confirm compatibility before installation.

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 439232 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.

For part number 439232, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ A-CLASS, MERCEDES-BENZ A-CLASS 1999, MERCEDES-BENZ A-CLASS 2000, MERCEDES-BENZ A-CLASS 2001. 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 fitment using part number 439232, the 12V 90A rating, 5 groove 51mm pulley, pad mount, direct fastening, and the electrical connector arrangement before ordering or fitting.
