Where is tensioner on serpentiine belt for 99 cutlass?

On a 1999 Oldsmobile Cutlass, the serpentine belt tensioner is typically located near the front of the engine, on the driver's side. It is a pulley that is spring-loaded and can be rotated to relieve tension on the serpentine belt for removal or installation. To adjust the tensioner, you generally use a wrench or socket on the tensioner’s arm to pivot it away from the belt. Always refer to the vehicle's service manual for specific details and diagrams.
