Valeo Alternator 12V 220A 439817

The Valeo Alternator 12V 220A is a new rotating electrical unit with part number 439817, supplied as each and covered by a one year warranty. It is specified with a 220 amp charge current, 12 volt output, and clockwise rotation, so it is suited to applications that call for those exact electrical and mounting details.

This alternator uses a 6 groove pulley, internal regulator, and four-point mounting with a quad leg alternator mount. Key mounting measurements include 127mm centre-to-centre, 61mm inside mounting legs, and an M8x1.25 / 9 pivot hole diameter. Those dimensions matter when matching the unit to the vehicle's original alternator arrangement.

Val eo is identified here as the brand and as the suit unit make, and the unit is described as a leading OE manufacturer and supplier for many euro vehicles. The connector detail is listed as no connector for revolution counter, so the electrical connection arrangement should be checked carefully before ordering.

Application and Buying Notes

Before buying, compare the part number 439817, the 12V system voltage, and the 220A charge rating against the vehicle's original alternator. Those values need to match the application requirements, especially where the vehicle uses a high-output charging system or a specific Valeo replacement.

Mounting details are just as important as electrical output. This unit is listed with a 6 groove pulley, clockwise rotation, 127mm mount centre to centre, 61mm inside mounting legs, M8x1.25 / 9 pivot hole diameter, and four-point mounting with a quad leg alternator mount. If any of those dimensions differ from the removed unit, fitment should be rechecked before installation.

The connector note also needs attention: this alternator is listed with no connector for revolution counter. That means the plug arrangement and any counter signal requirement should be checked against the original unit and the vehicle harness, rather than assuming a direct swap from shape alone.

Weight is listed at 7.6kg, which can help when comparing like-for-like against an existing alternator during parts identification. The regulator is internal, so there is no separate external regulator listed with this unit.

Where fitment is being checked against a vehicle, use the supplied application details as a guide and confirm the replacement against the original part number and physical mounting layout. Electrical output, pulley grooves, rotation direction, and connector style all need to align for the correct replacement choice.

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 439817 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.

Additional published details for cross-checking include Fastening Type Four-point mounting, Weight 7.6kg, Product Group 1 ROTATING ELECTRICAL, Part No. 439817, Brand VALEO, Description Valeo Alternator 12V 220A, Inside Mounting Legs 61mm, Pivot Hole Diameter M8x1.25 / 9, Pulley Outside Diameter 56mm, Regulator Type Internal.

Valeo Alternator 12V 220A. Part number 439817 should be checked first. Listed voltage is 12. Listed output rating is 220. 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 439817, 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 220 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A4, AUDI A4 2011, AUDI A4 2012, AUDI A4 2013. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 439817, 12V / 220A specification, pulley and mounting details, and the vehicle application before ordering. If the original alternator differs in rotation, connector style, or mounting pattern, it should not be assumed compatible.
