Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery for safety when working on electrical components.

2. Cabin Air Filter Replacement

• Tools Required: Screwdriver, vacuum cleaner.
• Remove the cabin air filter cover, usually located behind the glove compartment.
• Take out the old cabin air filter and inspect for dirt or mold.
• Clean out any debris in the filter housing using a vacuum.
• Install a new cabin air filter, ensuring it is oriented correctly.
• Reattach the cabin air filter cover securely.

3. Inspect and Repair Fluid Leaks

• Tools Required: Oil catch pan, flashlight.
• Check under the vehicle for any fluid pooling.
• If coolant is leaking, trace the leak back to the source (radiator, hoses, or water pump).
• Replace any damaged hoses or components as necessary.
• If oil is found, inspect the valve cover gasket and oil pan for leaks; replace gaskets if needed.

4. Check and Repair Exhaust System

• Tools Required: Wrench set, exhaust repair kit.
• Inspect the exhaust system for holes, cracks, or loose connections.
• Repair any damaged sections using an exhaust patch or replace the affected components.

5. Clean HVAC System

• Tools Required: HVAC cleaner spray, cloth.
• Access the HVAC system by removing the blower motor cover if needed.
• Spray HVAC cleaner into the intake vents and run the blower on high to circulate the cleaner.
• Allow the system to dry thoroughly before reassembling any components.
