You need to replace the compressor with a A/C compressor by-pass pulley, Part Number: 34150 autozone $28

There should be a sticker on the hood or the radiator support.

Tony,
If your serpintine belt fell off, and it is not broken, you have a much bigger problem then you think.
Before puttin a new belt on, check all pulleys, Power steerin, alternator, AC,Belt tensioner,waterpump The AC may or may not move ,
If one of those units don't move, don't put the belt on till you replace that which didn't move

very easy take a 5/8 socket on rachet on the furthest left pulley. Then pull rachet to driver side the pully wil move enough to remove belt make sure to keep tension on rachet and pulley while remon=ving belt. ther should be a belt schematic on to of radiator shroun for re install
