Apparently the serpentine belt was thrown off my 1998 Mercury Mystique. It appears in good condition. Should it be replaced or can it be reused? Also, do you have a belt diagram? Thank-you.

You can reuse it. But you need to find out why it was thrown off. Check all the pullies by grabbing them and checking for side to side movement, With the exception of the power steering pump pulley (which has some in and out play) they all should have no play. Just turn in nice smooth circles. Sorry I don't have the diagram, but there should be one under the hood. Sometimes on the bottom of the hood.

Hi, the belt can be reused, but you need to figure out why it came off. Check all pulleys for play and replace any accessory that has a loose pulley.
