What does a belt tensioner do?

It is meant to keep the drive belt, also known as the serpentine belt, in place and where it can do its work and able to deal with the torque coming from the crankshaft pulley, alternator, water pump, power steering pump, and other components.

What happens if my belt tensioner is damaged or isn’t working properly?
