Valeo Alternator 12V 180A 439818

The Valeo Alternator 12V 180A, part number 439818, is a new passenger alternator supplied as an OE product. It is rated at 180A and uses a 12V electrical system, making it important to match the charging setup and the original application before purchase.

This unit has an internal regulator, a 6 groove pulley with a 50mm outside diameter, and clockwise rotation. It uses direct fastening with a pad mount, a mount leg thickness of 70mm, and a mount centre-to-centre measurement of 56mm, so physical dimensions should be checked against the existing alternator.

The alternator is listed with OEM number A0009067702 and pin code IR228. It also has no connector for revolution counter, which matters when comparing the plug arrangement and wiring on the vehicle already fitted with the original unit.

At 7.64kg, this Valeo alternator is supplied as each, with a one year warranty. It is intended for buyers who need a precise replacement match based on the part number, mounting style, pulley configuration, and charging output rather than a generic universal unit.

Application and Buying Notes

Before ordering, compare the existing alternator’s part number, mounting layout, pulley type, and connector arrangement. This Valeo unit uses a pad mount, direct fastening, 56mm mount centre-to-centre, 70mm mount leg thickness, and a 6 groove pulley, so the physical match is just as important as the 180A rating.

The internal regulator and 12V specification need to align with the vehicle’s charging system. If the original alternator has a different regulator style, pulley section, or rotation direction, this replacement may not be suitable even if it appears similar at a glance.

The supplied fitment data includes Mercedes-Benz applications, but fitment should still be checked against the vehicle details and the original unit. The safest approach is to verify the part number 439818, OEM number A0009067702, and the pin code IR228 before fitting or ordering.

If you are replacing a worn alternator, confirm the belt drive setup, the wiring plug, and the mounting points on the vehicle. The note of no connector for revolution counter is especially relevant where the existing alternator uses a different auxiliary connection.

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 439818 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 439818, 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 passenger in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, 6-T 2009, 6-T 2010. 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.
