Fresh air is blown directly into the exhaust manifold, enabling faster heating of the catalytic converter, to help further oxidized of CO and HC in the exhaust gas of the engine, reducing the emission of harmful substances in the exhaust gas of car.

Make sure there is a belt routing diagram under the hood of your car so you know how to reinstall the belt. If not, take a picture of the belt routing with your phone before proceeding further.
Some older vehicles use a v-belt instead of a serpentine belt. In this case, loosen the pump mounting bolts and the adjustment bracket. Then, move the pump inboard until the belt can be removed.
If you have an older vehicle with a v-belt, move the pump outboard so the belt can be installed. Then, tighten down the pump mounting bolts and adjustment bracket.
