Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Remove the Old Belt

Tools Required: Socket set, serpentine belt tool (or wrench).
Locate the belt tensioner and use the serpentine belt tool to relieve tension on the belt.
Remove the belt from the pulleys, noting the routing path for reinstallation.

3. Inspect and Replace Components

Inspect the Tensioner:
- Check if the tensioner is functioning correctly; replace if it does not hold tension.
Inspect Pulleys:
- Spin the pulleys by hand to check for smooth operation; replace any that are damaged or worn.

4. Install the New Belt

Parts Required: New serpentine belt (ensure it matches OEM specifications).
Route the new belt according to the diagram often located on the engine bay or refer to the owner’s manual.
Use the tensioner tool to apply tension to the new belt, ensuring it is properly seated in all grooves.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and observe the belt's operation for any abnormal noises or slippage.
