Solution

1. Preparation

Tools Required: Socket set, torque wrench, belt tensioner tool, pry bar, flashlight
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Remove the Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram, usually found on a sticker near the engine bay.
2. Use the belt tensioner tool to relieve tension on the serpentine belt.
3. Slide the belt off the pulleys carefully and remove it from the engine.

3. Inspect Components

Sub-steps:
1. Check the belt tensioner for wear or improper operation; replace if necessary.
2. Inspect all pulleys for damage or misalignment; spin them to check for smooth operation.
3. Examine other accessory components (alternator, power steering pump, etc.) for issues.

4. Install New Serpentine Belt

Sub-steps:
1. Route the new serpentine belt according to the routing diagram.
2. Use the belt tensioner tool to apply tension and position the belt on the tensioner pulley last.
3. Ensure the belt is properly seated on all pulleys without twists.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Start the engine and observe the belt's operation, checking for any noise or misalignment.
3. If the problem persists, recheck alignment and tension of the belt.
