Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Damaged Belts

Remove the engine cover (if applicable) using a socket set.
Loosen the tensioner for the serpentine belt using a wrench.
Remove the serpentine belt from the pulleys.
Inspect the belt for cracks or fraying. If damaged, replace it with a new belt that matches OEM specifications.
Reinstall the new belt by routing it according to the belt routing diagram (usually found on a sticker in the engine bay).
Tighten the tensioner back to the specified torque.

3. Inspect and Replace Damaged Hoses

Check all rubber hoses for signs of melting or damage.
If any hoses are damaged, cut them away and replace them with new hoses of the correct diameter and type.
Secure all clamps to ensure there are no leaks.

4. Check and Repair Other Components

Inspect the alternator for any signs of wear. If necessary, replace it using appropriate tools.
Ensure that there are no foreign objects caught in the engine bay that could cause friction.

5. Final Assembly

Reconnect the battery.
Start the engine and listen for any unusual noises while checking for the burning smell.
