Can I get clarity on a few things before I change out my belt(s). 1) What is needed to be removed besides the air intake duct to get to the serpentine belt? I see coolant hoses, but do they just need to be unclipped from the plastic holders or do they need to be physically removed? 2) Can the a/c belt be removed after the serpentine belt is done or before? Is there a separate tensioner for that? Am I missing anything else? I'm going to do this for the first time this week.
