Valeo Alternator 12V 230A 439670

Valeo alternator, 12V and 230A charge rating, part number 439670. It is a new unit with an internal regulator, supplied as each, and listed with OEM number FG23S011. For buyers comparing replacements, the key identifiers here are the 12 volt system, 230 amp output, and the Valeo-specific application details.

This alternator uses a 7 groove pulley, twin leg mount, and a 53mm pulley outside diameter. Mounting dimensions listed are 75mm inside mounting legs, 126mm mount centre to centre, and a 10 / M10 pivot hole diameter. Those dimensions matter when checking whether the existing bracket arrangement and pulley alignment match your vehicle before ordering.

The unit weighs 7.66kg and carries a one year warranty. It is described as a leading OE manufacturer and supplier for many euro vehicles, which makes the part number and dimensions especially important when matching an existing alternator rather than relying on appearance alone.

Application and Buying Notes

Before ordering, confirm the vehicle uses a 12V charging system and that the alternator specification matches the 230A output listed here. The part number 439670, OEM number FG23S011, and pin code IR148 are the strongest identifiers for matching the correct replacement when the original unit is unavailable or difficult to read.

The mounting pattern is a practical check point. This alternator is a twin leg mount with 75mm inside mounting legs, 126mm mount centre to centre, and a 10 / M10 pivot hole diameter. If any of those dimensions differ from the existing unit or bracket arrangement, the part may not install correctly even if the outside shape looks close.

Pulley and regulator details also need attention. This unit has a 7 groove pulley with a 53mm outside diameter and an internal regulator. Those details should be compared with the vehicle’s existing alternator so the belt alignment, connector arrangement, and charging setup are consistent with the replacement part.

For workshop or DIY replacement, the weight of 7.66kg is useful when handling the unit and planning access to the mounting points. Because the application list is not fully broken down by engine or exact variant, it is best to use the part number and measured dimensions as the final confirmation step rather than assuming fit from make alone.

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 439670 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.

Valeo Alternator 12V 230A. Part number 439670 should be checked first. Listed voltage is 12. Listed output rating is 230. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439670, 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 230 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 2009, BMW 5 2010, BMW 5 2011. 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 fitment by matching part number 439670, OEM number FG23S011, pin code IR148, voltage, pulley type, and mounting dimensions against the vehicle and the original alternator before purchase.
