How do you adjust the serpentine belt on a Kia Sephia?
If you adjust the belt for the alternator. You must loosen the alternator bracket hex screws on both the top and botom of the alternator. This requires going under the vehicle. Then, loosen the tensioner bracket hex screw and adjust the tensioner hex screw that runs through that. When you get the propper tension, tighten all screws and you are done.
