Valeo Alternator 12V 150A 439647

The Valeo Alternator 12V 150A, part number 439647, is a new alternator supplied as each. It is listed with a 12V system, 150A power rating, internal regulator, and clockwise rotation, so it suits applications that match those core electrical and mounting details.

This unit uses a 6 groove pulley, 51mm pulley outside diameter, and four-point mounting with a quad leg alternator mount. Mounting measurements include 61mm inside mounting legs, 127mm centre to centre mounting, and an 8 / M8x1.25 pivot hole diameter. These dimensions matter when checking whether the alternator will physically locate correctly in the vehicle.

Valeo identifies this alternator with pin code IR167 and notes it has no connector for revolution counter. It is described as a leading OE manufacturer and supplier for many euro vehicles, and the listed fitment references include Renault Fluence, Renault Megane, and Renault Megane CC applications.

Application and Buying Notes

Before ordering, compare the part number 439647, the Valeo brand, and the 12V 150A specification with the unit currently fitted to the vehicle. The mounting pattern is just as important as the electrical rating here, because this alternator is listed with a quad leg mount, four-point fastening, 61mm inside mounting legs, and 127mm centre to centre.

Pay close attention to the pulley and connection details. This alternator uses a 6 groove pulley with a 51mm outside diameter and has no connector for revolution counter, so the replacement needs to match both the drive belt arrangement and the electrical connection style used in the application.

The rotational direction is clockwise, and the regulator is internal. Those details can affect compatibility even where the housing looks similar, so it is worth matching the old unit carefully against the listed IR167 pin code, pivot hole diameter of 8 / M8x1.25, and the stated alternator mount layout before fitting.

The fitment references point to Renault Fluence, Renault Megane, and Renault Megane CC applications, including several model years. That is useful as a guide, but the safest approach is still to verify the vehicle’s build details, the existing alternator markings, and the mounting measurements rather than relying on model name alone.

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 439647 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.

Valeo Alternator 12V 150A. Part number 439647 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439647, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using part number 439647, the Valeo reference details, and the vehicle’s mounting and connection setup before purchase.
