Installation Notes and Tips

Verify chassis-number notes before ordering, especially for Audi A6, Audi A6 Quattro, Audi Cabriolet, Audi 90, and Audi 90 Quattro applications. Replace the gasket during installation, clean the mounting surface thoroughly, and inspect the cooling system for contamination or belt-related wear before returning the vehicle to service. Confirm the part number PA618A against the existing pump and vehicle application data before installation.
