Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool if it has been running.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, ratchet, belt tensioner tool (if necessary).
Remove any engine covers that may obstruct access to the belts.
Check the condition of serpentine and timing belts for signs of cracking or fraying.
If worn, remove the old belt by releasing the tension using the belt tensioner tool.
Install the new belt, ensuring it is properly aligned with all pulleys.

3. Electrical System Check

Tools Required: Multimeter.
Check the battery voltage; it should be between 12.4-12.6 volts when the engine is off.
Start the engine and check the alternator output; it should be between 13.8-14.4 volts.
If the readings are outside these ranges, replace the battery or alternator as needed.

4. Inspect Tires and Wheel Wells

Tools Required: Jack, jack stands, tire pressure gauge.
Raise the vehicle using a jack and secure it with jack stands.
Inspect tires for uneven wear or damage that could cause a burning smell.
Check the wheel wells for any debris that may be contacting the tires.
