How do you change the serpentine belt on a Geo Storm?

To change the serpentine belt on a Geo Storm, first ensure the engine is off and cool. Locate the belt routing diagram, usually found on a sticker in the engine bay, and take note of the belt path. Use a wrench to relieve tension on the tensioner pulley, then slide the old belt off. Install the new belt by following the routing diagram, ensuring it's properly seated on all pulleys, and finally release the tensioner to secure the belt.
