- Inspect the coolant reservoir; ensure it is filled to the recommended level. If low, top it off with a mixture of coolant and distilled water.
Inspect for Leaks:
- Visually check hoses and gaskets for leaks. Replace any damaged components.

3. Brake System Inspection

Remove the wheels to access the brake components.
Inspect brake pads and rotors for excessive wear or overheating signs. Replace if necessary.
Check the caliper for sticking pistons or brake fluid leaks.

4. Exhaust System Inspection

Inspect the exhaust manifold and pipes for any signs of melting insulation or damage.
Look for any loose connections or exhaust leaks that could cause burning smells.

5. Reassembly and Testing

Reinstall any removed components, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the battery.
Start the vehicle and observe for any unusual smells or noises.
