Tools Required: Socket set, belt removal tool (if needed).
Locate the serpentine belt tensioner and use a socket to relieve tension on the belt.
Slide the belt off the tensioner and note the routing path.
Remove the belt from all driven components.

3. Inspect Components

Check the tensioner for wear; replace if it does not hold tension properly.
Inspect idler pulleys and accessory components for damage or wear.
Replace any worn pulleys or components before installing the new belt.

4. Install the New Serpentine Belt

Parts Required: New serpentine belt (ensure it matches OEM specifications).
Follow the belt routing diagram located on the engine bay or the old belt's routing.
Loop the new belt around the pulleys, leaving the tensioner for last.
