How do you put a serpentine belt in a suzuki Reno?

look in from the passanger side of the engine compartment there is a spring loaded idler which can be accessed with a 15mm box wrench ( the idler has a little arrow on it) as you move it clockwise/counter clockwise it will increase or decrease the tension on the serpentine belt(observe this with the car not running!!!) you probably should remove the air cleaner black box,and the passanger side under wheel well black splash guard,you'll have more room to work.....the job is realatively easy.......just make note of the way the belt goes around each pulley....that idler can be accessed from under that wheel well also if you should have to get Moore deflection
