Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Gather tools: socket set, screwdrivers, oil catch pan, and rags.

2. Inspect for Leaks

Open the hood and visually inspect the engine compartment.
Look for oil or coolant leaks around the engine block and under the vehicle.
Clean any visible leaks and identify their source.

3. Check Oil Level and Condition

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If the oil is low, add the appropriate type of oil (consult the owner’s manual).
If the oil appears burnt or contaminated, consider an oil change.

4. Examine Belts and Hoses

Visually inspect all belts for cracks, fraying, or signs of burning.
Check hoses for any soft spots, cracks, or melting.
Replace any damaged belts or hoses as necessary.

5. Inspect the Exhaust System

Check the exhaust pipes for any visible holes, corrosion, or abnormal wear.
Listen for unusual noises when the engine is running which may indicate a leak.
Repair or replace any damaged sections of the exhaust system.

6. Verify Brake Components

Lift the vehicle safely using jack stands and remove the wheel to access the brake assembly.
Inspect brake pads for excessive wear and ensure they are not overheating.
Replace any worn brake components as needed.
