Toyota Repair: 2001 toyota sienna van replace ac belt, alternator belt, power steering pump

Question
Does a 2001 toyota sienna have a tensioner to replace the drive belt ( AC and Altenator ) and if not what do I do to replace the belt? Please help thank you

Answer
It doesn't have a tensioner for either one, The a/c and alternator belt tension is adjusted by moving the alternator in the bracket,both use the same belt, there is a set bolt and an adjustment bolt which tightens or loosens it, there is a power steering belt adjustment by moving the power steering pump in the sdjustment slot.
