Use an 18mm wrench and place it on the belt tensioner pulley bolt. - The bolt has reverse threading so it will tighten as you apply counterclockwise force. Pull the wrench back towards the passenger compartment with your left hand (It takes some strength but it can be done). Then pulll off the belt from above the alternator. Careful not to let go for it'll ruin your day. Follow the schematic located on the front left of the car as you replace the everwinding belt. Once everything is aligned pull back on the tensioner once more as you finally engage the belt on the alternator. You're done.
