My rule of thumb on how tight the belt should be is pushing down on the belt in between two pulleys that's the farthest apart.. A half inch of slack would be a good start and re-check it for proper operation such as running the A/C and turning the steering wheel from the lock to lock position. if you don't hear any belt squeel then turn the ignition off and tighten the pulley retaining nut and your done. If it squeels, tighten the belt some more to a quarter of an inch slack then re-check..
