Put an 18mm wrench on the lower tensioner belt and rotate CCW to loosen the tension. Remove the belt from around the alternator pulley, and slowly release the tensioner. Unwrap the belt from all the pulleys and install the new belt following the belt diagram located near the radiator support. ALWAYS make sure the grooved side of the belt is contacting the grooved pulleys, and the smooth side of the belt is contacting the smooth pulleys (Idler pulleys).

Place a wrench on the pulley that pulls the belt tight. Its not the A/c, alternater, water pump, or fan but the other one. This should make the belt loose then pull it off. Replace with a new belt. Ensure that the belt is in the correct sequence as it was before.
