Valeo Alternator 12V 120A New 439299

The Valeo Alternator 12V 120A, part number 439299, is a new rotating electrical unit supplied as each. It is rated at 120 amps and 12 volts, with an internal regulator and a 6 groove pulley, so it suits applications that match those electrical and mounting details.

This alternator uses a single leg mount with a single pivoted lever fastening type, a 157mm centre-to-centre mount measurement, 56mm mount leg thickness, and a 10mm pivot hole diameter. Those dimensions are important when comparing the unit against the vehicle’s existing alternator or the replacement specification.

The unit weighs 6.5kg and is listed with Pin Code IR173. It also has no connector for a revolution counter, which is a useful check where the original installation includes a tacho or counter signal and the replacement must match the existing connector arrangement.

Application and Buying Notes

Before buying, compare part number 439299 with the alternator currently fitted to the vehicle, then check the 12V system, 120A charge current, and internal regulator arrangement. Matching the electrical rating matters because alternators with different output levels or regulator types may not interchange even when the mounting looks similar.

The mounting details are just as important as the electrical rating. This Valeo unit has a single leg mount, single pivoted lever fastening, 157mm mount centre-to-centre, 56mm mount leg thickness, and 10mm pivot and adjusting holes. If any of those points differ from the original alternator, the unit should be checked carefully before purchase.

The pulley configuration is a 6 groove pulley with a 59mm outside diameter. That needs to align with the vehicle’s belt setup. If the belt profile or groove count does not match, the alternator may not be suitable even if the plug and mounting points appear close.

This alternator is listed with no connector for a revolution counter, so it is worth checking whether the original vehicle uses that function. Where the existing alternator has a counter or tacho connection, the replacement must be verified against the vehicle’s wiring and connector layout.

The unit is supplied new, weighs 6.5kg, and carries a one year warranty. Those details help when comparing like-for-like replacements, especially where a customer is replacing a worn original unit and wants a direct substitute rather than a remanufactured part.

If you are matching by vehicle application, use the Mercedes-Benz C-Class fitment note as a guide only and verify the exact engine, year, and installed alternator details against the vehicle. Alternator fitment can vary within a model range, so the safest approach is to confirm both the part number and the mounting measurements.

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 439299 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 One Year, Mount Leg Thickness 56mm, Pivot Hole Diameter 10, Pulley Outside Diameter 59mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 157mm, Alternator Charge Current [A] 120.

Additional published details for cross-checking include Fastening Type Single pivoted lever, Weight 6.5kg, Product Group 1 ROTATING ELECTRICAL, Part No. 439299, Brand VALEO, Description Valeo Alternator 12V 120A, Adjusting Hole Diameter 10, Pin Code IR173, Power Rating (Amp) 120, Pulley Section 6 Groove.

Valeo Alternator 12V 120A. Part number 439299 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 439299, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 2000, MERCEDES-BENZ C-CLASS 2001, MERCEDES-BENZ C-CLASS 2002. 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.

Compatibility note: Please confirm compatibility using part number 439299, the 12V 120A rating, the internal regulator, the 6 groove pulley, and the mounting measurements before ordering. Vehicle application details provided are limited, so final fitment should be checked against the existing alternator and wiring layout.
