Confirm that the application calls for a mechanical water pump with a metal impeller and the included sealing components.

Quality Assurance

VAICO identifies this as an aftermarket cooling component for the listed applications. Part number V40-50043 should be matched to the vehicle’s exact cooling system configuration and fitment notes before installation.
