First, you'll need to loosen the bolts to the air pump on the driver's side of the engine, to remove that belt from the crank shaft and water pump pulleys. Then do the same for the power steering pump, to remove it's belt from the crank shaft pulley. Now loosen the two bolts on the alternator, turn the tensioner bolt counter-clockwise to release the tension from the belt. Then remove it from the pulleys, and work it over the blades of the fan. Installation is reverse of removal. When tightening the belts, you want between 1/4 to 1/2 an inch of slack depending on the distance between the pulleys.
