My serpentine belt suddenly became very loose. I removed the passenger side front wheel and tried to tighten the pulley. The bolt in the middle of the pulley was not loose but yet I could easily move the pulley up and down by hand. How do I tighten the pully so the belt is no longer slack?

Perhaps there is some device behind the pulley that 'ratchet ups' that is now broken?
