You should change the drive belt when you see cracking underneath the belt where it rides against the pulleys(the grove part of the belt)or you need to replace it when it continously squeals
No timing belt but a timing chain

Remove belt and tensioner should just be bolted to engine
Insert a socket or wrench on the spring-loaded serpentine belt tensioner then pull back; the belt will loosen.
The 3.8L engine has a timing chain.
The 3.1 litre V6 engine in a 1997 Buick Century has a timing CHAIN
This engine uses a chain to drive the single cam. Pushrods and rockers operate the valves on each head. There is no timing belt to break. The serpentine belt only drives the water pump, power steering pump, alternator, and air conditioning compressor. If this is a supercharged engine, a separate belt drives the supercharger.
The lower part of the drive belt runs around the tentioner. It's where the adjustment is made to tighten or loosen the belt.
The Buick that was supercharged was called the Ultra. On the engine there is another unit mounted on top of the engine. It is driven by a separate belt from the drive shaft. The engine without the supercharger has only one serpentine belt.
the diagram is in the left corner closest to the passenger seat
