Application and Buying Notes

When replacing an alternator, the most useful checks are the part number, OEM number, mounting style, pulley configuration, and electrical output. For this unit, the key identifiers are 439546, 642 154 04 02, 12V, 180A, direct fastening, and a 7 groove pulley with clockwise rotation.

This alternator uses an internal regulator and a pad mount, which need to line up with the original unit. A mismatch in mounting type, pulley groove count, pulley diameter, or rotation can stop the alternator fitting correctly even when the vehicle make appears similar.

The listed connector detail is also important. This unit is described as having no connector for revolution counter, so the wiring and sensor arrangement on the vehicle should be checked against the existing part. That kind of detail is often what separates a correct fit from an incorrect one.

Fitment names supplied include a spread of Chrysler, Jeep, and Mercedes-Benz applications, but the list is broad rather than a substitute for checking the exact vehicle variant. Use the supplied identifiers first, then compare the old alternator side by side with this Valeo unit before fitting.

Because the item is supplied as each and carries no warranty, it is worth confirming every visible and electrical match before purchase. If the existing alternator has the same 12V 180A rating, 7 groove pulley, 50 mm pulley outside diameter, and direct fastening layout, that is a strong starting point for compatibility checking.

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 439546 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty No Warranty, Power Rating (Amp) 180, Pulley Section 7 Groove, Rotation CW, Voltage 12, OEM Number 642 154 04 02, Fastening Type Direct fastening, Weight 8.13kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. 439546, Brand VALEO, Description Valeo Alternator 12V 180A, Pin Code IR169, Pulley Outside Diameter 50mm, Regulator Type Internal, Suits Unit Make Valeo, Alternator Mount Pad, Alternator Charge Current [A] 180.

Valeo Alternator 12V 180A. Part number 439546 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 439546, 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.

Compatibility note: Confirm fitment using the part number 439546, OEM number 642 154 04 02, and the physical details of your existing alternator, including 12V, 180A, 7 groove pulley, 50 mm pulley outside diameter, clockwise rotation, internal regulator, and direct fastening mount. Do not rely on vehicle make alone.
