You will find a number of bolts than run through the compressor in a fore/aft direction. Loosen all of them and then find the stud and nut that serves as the tensioner. Loosen the tensioner until you can get the belt off. Then remove the brackets that secure the a/c hoses in place. Tie some wire or something to the compressor to support, then remove all those fore/aft bolts completely. You can then use the wire to lift the compressor up out of the way without disconnecting the lines. Don't forget the hose brackets for the hose that goes across the top of the motor.
