To adjust the tension on a 1994 Chevy pickup's serpentine belt, locate the belt tensioner, which is typically a spring-loaded arm. Use a wrench or a ratchet to turn the tensioner pulley in the direction indicated (often counterclockwise) to relieve tension on the belt. Once the belt is loosened, you can replace it if needed or adjust it as necessary. Ensure the belt is properly seated on all pulleys before releasing the tensioner to apply proper tension again.
