A vacuum pump is a mechanical component that generates vacuum required by the relevant vehicle systems. On diesel commercial vehicles, the correct pump should not be selected by vehicle model name alone.
What data should be checked?
Key data includes the OEM reference, engine type, vehicle generation, production year and connection geometry of the installed part. AFES product data includes references such as 93BB 2A451 AD, 7C16 2A451 CB, GK2Q 2A451 AC and BK3Q 2A451 FC.
Why is the OEM code stronger than the model name?
Long-running vehicle families such as Transit can include many engines and technical revisions under the same model name. The OEM code provides a more precise starting point for distinguishing these variants.
What is shown on AFES product pages?
Each product page combines the AFES code, primary and alternative OEM references, compatible vehicle information, product image and a technical verification note.
