Solution

1. Preparation

Tools Required:
- Socket set
- Wrench set
- Serpentine belt tool or breaker bar
- Torque wrench
- Safety goggles
Sub-steps:
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the negative terminal of the battery to prevent electrical issues.
- Allow the engine to cool completely.

2. Remove the Old Serpentine Belt

Locate the serpentine belt routing diagram, typically found on a sticker in the engine compartment.
Use the serpentine belt tool to rotate the tensioner pulley counterclockwise to relieve tension on the belt.
Carefully slide the belt off the pulleys, starting from the tensioner pulley.
Inspect the belt's path to ensure proper installation of the new belt later.

3. Install the New Serpentine Belt

Obtain a new serpentine belt that matches the specifications for the 2012-2017 Toyota Camry.
Refer to the routing diagram to ensure correct placement of the new belt over the pulleys.
Start by looping the new belt over the crankshaft pulley, then follow the belt routing as indicated.
Rotate the tensioner again and slip the belt over the tensioner pulley last to ensure proper tension.

4. Verify Installation

Ensure the belt is properly seated on all pulleys and aligned correctly.
Reconnect the negative battery terminal.
Start the engine and observe the belt in operation for any signs of slipping or misalignment.
