Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight, torque wrench, multimeter
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical issues while inspecting components.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Remove the engine cover if applicable.
2. Visually inspect the serpentine and timing belts for cracks, fraying, or excessive wear.
3. If damaged, loosen the tensioner using a socket and remove the belt.
4. Install the new belt, ensuring it aligns properly with all pulleys.
5. Re-tighten the tensioner to the manufacturer’s specifications (refer to the service manual for torque values).

3. Check and Replace Faulty Components

Sub-steps:
1. If the diagnostic scan reveals any trouble codes, follow the code to determine the faulty component (e.g., alternator, water pump).
2. Disconnect the battery again as needed.
3. Remove the faulty component (e.g., alternator) by disconnecting electrical connectors and loosening mounting bolts.
4. Install the new component, ensuring all connections are secure and bolts tightened to specifications.

4. Reconnect Battery and Test

Reconnect the battery and ensure all connections are secure.
Start the engine and listen for any abnormal noises.
Monitor for the burnt rubber smell and check for any warning lights on the dashboard.
