I just replaced the water pump on my moms Taurus and now the part the belt goes around won't turn. Can anyone tell me why and or what to do?

. OHV or DOHC engine?

The reference is not real clear. Are you referring to the water pump pulley or the idler pulley?

. Did you route the serpentine belt correctly?
