there should be 3 or 4 bolts that hold pulley on, just remove these bolts a pulley should come off. but remove belt first ! if pulley keeps turning while removing bolts. you can hold it stationary with a scredriver or similar.
The main pulley on which the serpentine belt goes on in a 1997 Chevy Lumina LTZ is the crankshaft pulley. The crankshaft pulley plays a role in the wheels turning and powering the alternator and power steering pump.
I belive that there is no adjustment on the serp belt on your lumina. Should be a spring loaded tensioner. If you are having problems with the belt slipping you most likely need to replace the belt/ tenssioner.
why
Typically, there is one pulley that is mounted on a spring arm to maintain proper belt tension. Just turn the bolt on the idler pulley and the tensioner will release.
You can change the serpentine belt by loosening the tensioner pulley. When the tensioner pulley is loose and the serpentine belt will become loose. Put the new serpentine belt on and tighten the tensioner pulley.
