Yesterday..my serpentine belt "came off" the pulley assembly..I notice today that the main pulley on the engine block at the bottom has appeared to slide out about 1/2 "...thrwoing off the belt alignement. There is one hex bolt in the center of the lower pulley...can I just tighten this up and will it pull the pulley back the 1/2 inch to the engine block...or is there something else major going on here ?
