Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal with a socket wrench to prevent electrical shorts.
Allow the engine to cool if it has been running.

2. Remove the Old Serpentine Belt

Locate the serpentine belt tensioner, typically near the front of the engine.
Use a socket wrench or a serpentine belt tool to rotate the tensioner counterclockwise, which will relieve tension on the belt.
While holding the tensioner, carefully slide the belt off the pulleys.
Take note of the belt routing or refer to the belt routing diagram usually found on a sticker in the engine bay.

3. Install the New Serpentine Belt

Position the new serpentine belt over the appropriate pulleys following the noted routing.
Again, rotate the tensioner counterclockwise to allow for the new belt to be slipped over the tensioner pulley last.
Ensure the belt is seated properly in the grooves of all pulleys.

4. Final Checks

Double-check the belt routing and ensure it is correct.
Reconnect the negative battery terminal.
Start the engine and observe the belt in operation for any signs of misalignment or noise.
