depends on whether you are talking about the inside belt (closest to the engine) or the outside belt (closest to the cooling fan). Outside belt - loosen the alternator bolt at the top (the one that slides in the curved groove on the bracket) dont take it all the way out, just loosen it. On the bottom of the alternator there is another long bolt that needs to be loosened as well. The alternator should swivel in towards the engine giving enough slack to take the belt off or whatever needs to be done. Inside belt - The idler pulley (passenger side of the engine under the big a/c compressor) There is a bolt on the inside of the bracket that slides in a groove similar to the one on the alternator. It is hard to get to, but that is the only way to take the tension off the inside belt. Loosen the bolt on the inside of the bracket, then loosen the bolt on the outside of the bracket where the pivot arm bolts to the mounting bracket. The pulley should swing up towards the top of the engine giving the slack needed.
