I will try to give you step by step detail.

There is a 12 mm nut by the power steering pump. This 12 mm nut has to be cracked loose. Then there is another 12 mm long adjuster bolt, that you turn counter clock wise to loosen tension on the belt, and clock wise to tighten. After you have the belt back on and you adjusted it tight. Then lock the 12mm nut by the power steering pump.

Almost the same directions for the Alternator/Ac belt. There is a idler pulley that is the adjuster. In the center of the pulley there is a 14 mm nut. Just crack that loose and there is a 8 mm head on the adjuster bolt, which is located right above the compressor. Again counter clock wise to loosen, clock wise to tighten. After belt is on tight, then lock down the 14 mm nut on the pulley.

Using the image I gave you, and these directions.

If you have any more questions, please feel free to ask. Thanks Jay!
