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 11734 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.

Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-11734N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Opel - Europe ASTRA GTC J Eng.A 20 DTH 2.0 CDTI 121kw, Opel - Europe ASTRA J Eng.A 20 DTH 2.0 CDTI 121kw, Opel - Europe ASTRA J Sports Tourer Eng.A 20 DTH 2.0 CDTI 118kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 120A, Rotation: CW, Pulley Class: SC6, then cross-check OE numbers Opel 1204642, Valeo 440621, TG12C036, TG12C143.

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 11734. That usually narrows the match quickly.
