Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect and Replace Worn Belts

Inspect the serpentine and timing belts for signs of cracks, fraying, or glazing.
If any damage is found, remove the old belt by loosening the tensioner and carefully sliding the belt off the pulleys.
Install the new belt, ensuring it is properly aligned with all pulleys. Use the appropriate tensioner settings as specified in the vehicle’s service manual.

3. Check and Replace Brake Components

Inspect brake pads and rotors for excessive wear. If the pads are worn down, remove the wheel and inspect the brake assembly.
Replace worn brake pads and resurface or replace rotors if necessary. Ensure to apply brake grease to the contact points.
Reassemble the wheel and lower the vehicle.

4. Inspect and Replace Damaged Hoses

Check hoses for any signs of cracks or leaks. Pay special attention to the rubber hoses connected to the cooling system.
If damaged, remove the old hose by loosening the clamps and carefully detaching it.
Install the new hose, ensuring it is secured with clamps and does not interfere with moving parts.

5. Monitor and Test

Reconnect the battery and start the engine.
Allow the engine to warm up while monitoring for any unusual smells or sounds.
Take the vehicle for a test drive to ensure the burning smell has dissipated and check that all systems are functioning correctly.
