Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace Damaged Components

Inspect Belts and Hoses:
1. Visually examine the serpentine belt and any other rubber hoses for signs of wear or damage.
2. If damaged, remove the serpentine belt using a ratchet and socket to release tension.
3. Install a new belt by routing it according to the diagram located on the engine bay.
Inspect Brake System:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads and rotors for signs of excessive wear or overheating.
3. If worn, replace the brake pads and resurfacing or replacing the rotors as necessary.

3. Clean and Repair Affected Areas

Clean Any Residue:
1. If any fluids have leaked onto hot components, clean the area with a degreaser.
2. Allow the area to dry to prevent further burning odors.
Check for Foreign Objects:
1. Inspect the engine bay and exhaust system for any foreign objects.
2. Remove any debris that may be causing the burning rubber smell.
