- Inspect the coolant reservoir and ensure it is filled to the recommended level.

3. Brake Inspection

Inspect Brake Components:
- Remove the wheel if necessary to access the brake assembly.
- Check brake pads for excessive wear or overheating (burnt smell).
- Replace any worn or damaged brake components as needed.

4. Replace Damaged Components

Belts and Hoses:
- If any belts or hoses show signs of melting or wear, replace them with OEM or high-quality aftermarket parts.
- Ensure all connections are secure and properly routed.

5. Final Checks

Reassemble any components that were removed during inspection.
Start the engine and allow it to idle while monitoring for any signs of burning smell or leaks.
