Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect and Replace Engine Oil

Step 1: Remove the engine oil dipstick and check the oil condition; if it's dark or has a burnt smell, it needs to be changed.
Step 2: Prepare to change the oil by placing a drain pan under the oil pan and removing the drain plug.
Step 3: Allow the old oil to drain completely, then replace the drain plug and torque it to the manufacturer's specification (usually around 25 ft-lbs).
Step 4: Replace the oil filter using an oil filter wrench and lubricate the new filter’s rubber seal with new oil before installing it.
Step 5: Refill the engine with the appropriate type and amount of oil (typically 5W-20 or 0W-20, depending on the model year).

3. Brake Inspection and Maintenance

Step 1: Remove the wheel to access the brake components.
Step 2: Inspect brake pads for excessive wear; if they are less than 3mm thick, replace them.
Step 3: Check brake rotors for signs of scoring or overheating; resurfacing or replacing may be necessary.
Step 4: Ensure calipers are functioning properly and not sticking; clean or replace as needed.

4. Check Hoses and Belts

Step 1: Visually inspect all hoses and belts in the engine bay for cracks or signs of melting.
Step 2: Replace any damaged hoses or belts immediately to prevent further issues.

5. Monitor for Leaks

Step 1: After repairs, start the engine and allow it to run while monitoring for any fluid leaks.
Step 2: Identify and repair any leaks that could contribute to burning smells.
