Valeo Alternator 12V 120A Part No. 439395

This Valeo alternator is a 12V, 120A unit, part number 439395, supplied as a new replacement alternator rather than a remanufactured unit. It is listed with a pad mount, direct fastening type, and a 6 groove pulley, so the physical mounting and pulley style should be checked carefully against the original unit before ordering.

The unit is identified as Valeo brand, with a regulator type of internal and a connector/clamp described as no connector for revolution counter. Mount centres are listed at 164mm and 177mm, with additional dimensions including mount leg thickness of 70mm, adjusting hole diameter of 9mm, pivot hole diameter of 9mm, and pulley outside diameter of 57mm.

For buyers replacing a charging system component, the key figures here are the 12 volt system voltage, 120 amp charge current, and the stated Valeo unit make. These details matter because alternators must match the vehicle’s electrical setup, mounting arrangement, and pulley configuration, not just the overall appearance of the unit.

Application and Buying Notes

The safest way to buy this alternator is to match the part number 439395, then confirm the mounting style, pulley section, and electrical arrangement on the vehicle. This unit is a 12V, 120A Valeo alternator with an internal regulator, so it is important that the vehicle’s charging system is designed for that specification rather than relying on a visual match alone.

Check the physical dimensions against the removed unit, especially the 164mm and 177mm mount centres, the 56mm centre dimension, and the 70mm mount leg thickness. The adjusting hole diameter and pivot hole diameter are both listed at 9mm, and the pulley is a 6 groove design with a 57mm outside diameter. Those measurements can be the difference between a direct replacement and a part that will not align correctly.

Because this alternator is described as having no connector for revolution counter, it is worth checking the connector style on the original part before ordering. Electrical plug arrangement can vary even when the charge rating is the same, and the wrong connector detail can stop a straightforward installation.

This is a new alternator and carries a one year warranty. That warranty period is useful for peace of mind, but it does not replace the need to confirm fitment, belt alignment, and mounting position. If the original alternator was Valeo, the listed unit make may help narrow the match, but the final check should always be against the physical unit and the application details on the vehicle.

If you are unsure whether your car uses the same charging output or pulley setup, compare the old alternator before removing the belt completely. Confirm the number of grooves on the pulley, the pad mount style, and whether the alternator is mounted by direct fastening. Taking these checks before purchase helps avoid delays and returns.

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 439395 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 439395, 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.

Compatibility note: Please confirm compatibility by matching part number 439395 and checking the original alternator’s mount style, pulley section, electrical connector, and measured dimensions against the details listed here.
