Consider replacing the belt and tensioner when replacing other system components such as the alternator, power steering pump, or AC compressor.
A system is only as good as its weakest link, so we say, “remove it and replace it” when servicing a component that requires any kind of belt removal.
Belts and tensioners are designed to the same life cycle. When a high-mileage belt is replaced, the tensioner has likely met its design cycle as well.
