Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery cable to ensure safety during the repair.
Allow the engine to cool down before starting work.

2. Remove the Old Belt

Tools Required: Socket set, belt removal tool (if available)
Locate the serpentine belt tensioner, and use a socket or belt tool to relieve tension on the belt.
Slide the belt off any pulleys, starting with the tensioner.
Carefully remove the belt from the engine compartment.

3. Inspect Components

Check the tensioner pulley for signs of wear or damage. Replace if necessary.
Inspect all accessory pulleys for damage or misalignment and replace if required.

4. Install the New Belt

Parts Required: New serpentine belt (specific to the engine variant)
Route the new belt according to the belt routing diagram typically found on a sticker in the engine bay.
Use the tensioner to apply tension on the new belt, ensuring it is seated properly on all pulleys.

5. Reconnect Battery and Test

Reconnect the negative battery cable.
Start the engine and observe the belt operation for any unusual noises or misalignment.
Check the functionality of accessories (power steering, A/C, etc.) to ensure they are operating correctly.
