Solution

1. Preparation

Safety Warning: Ensure the engine is cool before inspecting under the hood.
Gather necessary tools and parts.

2. Inspect Engine Bay

Open the hood and visually inspect for any fluid leaks (coolant, oil, fuel).
Check hoses and fittings for cracks or damage.
Use a flashlight to look in hard-to-see areas.

3. Check Cabin Air Filter

Locate the cabin air filter access panel (usually behind the glove compartment).
Remove the filter and inspect it for dirt, debris, or mold.
Clean the filter housing with a damp cloth and replace the filter if necessary.
Parts Required: New cabin air filter (if needed).

4. Examine Brake System

Check brake pads for wear. If they are worn down or burnt, replace them.
Inspect brake fluid level and condition. Top off or replace fluid if necessary.
Parts Required: New brake pads (if needed), brake fluid.

5. Inspect Exhaust System

Visually check the exhaust system for holes, cracks, or loose connections.
Listen for unusual sounds that may indicate exhaust leaks (hissing or tapping).
If any leaks are found, repair or replace the affected components.
