Valeo Alternator 12V 140A Part No. 439393

The Valeo Alternator 12V 140A, part number 439393, is a new alternator supplied as an each unit for rotating electrical applications. It is rated at 140 amps and 12 volts, with a clockwise rotation and direct fastening mount, so the main installation checks are the mounting style, pulley layout, and electrical connection style on the vehicle.

Key mechanical details include a 6 groove pulley with a 56mm outside diameter, internal regulator, pad alternator mount, and a mount leg thickness of 70mm. The unit weighs 6.97kg and is listed with pin code IR139. These details matter because alternators must match the vehicle’s mounting points and belt drive arrangement as well as the charging specification.

Valeo is noted here as a leading OE manufacturer and supplier for many euro vehicles. The fitment information provided points to selected Audi, Skoda, and Volkswagen applications, including Audi A3, Skoda Octavia, Skoda Superb, Volkswagen EOS, and Volkswagen Golf. As with any alternator, the part number and application details should be checked carefully before purchase.

Application and Buying Notes

Before ordering, confirm the vehicle uses Valeo part number 439393 and check that the alternator setup matches the listed 12V, 140A rating. The charging output must suit the vehicle’s original electrical system, and the replacement needs to align with the existing mount style, pulley section, and rotation direction.

The pulley details are especially important here: this unit has a 56mm outside diameter, 6 groove pulley, and clockwise rotation. If the belt drive layout or pulley style differs, the alternator may not be the correct match even if the vehicle appears similar. The internal regulator and pad mount are also important checkpoints when comparing the old unit.

The connector note should be checked as well. This alternator is listed with no connector for revolution counter, so the vehicle’s wiring arrangement should be compared against the existing alternator before purchase. Mount leg thickness is listed at 70mm, which is another useful measurement when confirming interchange.

If the original alternator is unavailable for comparison, match as many identifiers as possible: Valeo brand, part number 439393, 12V system, 140A output, 6 groove pulley, direct fastening, and IR139 pin code. The more of these details that align, the less risk there is of ordering the wrong unit.

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 439393 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 Three Years, Pin Code IR139, Pulley Outside Diameter 56mm, Regulator Type Internal, Suits Unit Make Valeo, Alternator Mount Pad, Alternator Charge Current [A] 140, Connector / Clamp No Connector for Revolution Counter.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. 439393, Brand VALEO, Description Valeo Alternator 12V 140A, Mount Leg Thickness 70mm, Power Rating (Amp) 140, Pulley Section 6 Groove, Rotation CW, Voltage 12.

Valeo Alternator 12V 140A. Part number 439393 should be checked first. Listed voltage is 12. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. 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 439393, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A3, AUDI A3 2003, AUDI A3 2004, AUDI A3 2005, SKODA OCTAVIA, SKODA OCTAVIA 2005. 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: Always confirm fitment using part number 439393 and the vehicle’s exact alternator details, including voltage, amperage, pulley section, mount style, rotation, and connector arrangement before ordering.
