It isnt that easy. There are two belts. One from the crank to the water pump pulley and then the generator belt is behind that one. I agree taking the hood, grill and radiator off is the best way to do it. Gives you the most room and access to the water pump. That belt is adjusted by turning the adjusting ring on the front of the water pump. This is also the front half of the pulley. Do them both while you are there. Check the water pump out closely too. Make sure the bearing and seal are in good condition, not leaking and smooth spinning.
