Each Bosch auxiliary water pump is tested for proper function, torque integrity, and vacuum sealing to help verify impeller-to-shaft engagement and housing sealing performance. Bosch also checks fitment against OE mating parts and accessories, including related components such as pulleys, housings, and tensioners, to confirm application accuracy for Mercedes-Benz cooling system service.
