If it's at the belt wear indicator go ahead and replace it like you are. I don't think I've ever saw in the Ford workshop manual about replacing the belt tensioner at a certain mileage. But, I never did look.
A good rule of thumb is just replace it say if you're replacing the belt at 100k then you should definitely replace the tensioner.
