Product Advantages

Alternator matching focuses on amperage, voltage, pulley configuration, regulator/fan design, plugs, and OE replacement references.

Fitment-first matching

CF-21420N is prepared for alternator sourcing with Part No, OE, Lester number, and application records checked together.

Quality and test focus

Core specifications such as voltage, power or amperage, rotation, teeth, and design are reviewed before sample or bulk quotation.

Replacement sourcing support

MFR VALEO and replacement references including 21420 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Share target quantity, destination, sample need, and packaging requirement so Crankvia can confirm the practical supply path.

Application Information

Application records are provided as compatibility references. Confirm OE number, vehicle configuration, engine, and market version before final ordering.

How do I confirm CF-21420N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Opel - Europe ARENA Box Eng.25 DG, 25 DM 2.5 D 55kw, Opel - Europe ARENA Bus Eng.25 DG, 25 DM 2.5 D 55kw, Opel - Europe MOVANO Box (F9) Eng.S8U 770, S8U 772 2.5 D 59kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Part Type: Alternator, ACES Records: 10, then cross-check OE numbers Renault 7700300408, 7711134618, Valeo A13VI179.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 21420. That usually narrows the match quickly.
