Re: tensioner, it is normal for there to be some movement. It's pretty difficult to put one of these on incorrectly, there's an alignment tab that fits into a recess on the water pump housing. It is possible for the spring to break or fatigue, which could cause excessive oscillation, but it's likely that you're seeing normal tensioner behavior.
