How do you install a belt tensioner on 1992 S-10?

To install a belt tensioner on a 1992 S-10, first, disconnect the negative battery cable and remove any components obstructing access to the tensioner. Loosen the tension on the serpentine belt using a wrench on the tensioner pulley, then remove the old tensioner by unbolting it from the engine. Position the new tensioner in place, bolt it securely, and reattach the serpentine belt, ensuring it is properly aligned on all pulleys before reconnecting the battery.
