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 to avoid electrical shorts.

2. Replace Cabin Air Filter

• Locate the cabin air filter access panel (usually behind the glove compartment).
• Remove the screws or clips holding the panel in place.
• Take out the old cabin air filter and clean any debris from the housing.
• Install the new cabin air filter, ensuring it is oriented correctly.
• Reattach the access panel.

3. Address Coolant Leaks

• Inspect the radiator and hoses for cracks or leaks.
• If a leak is found, tighten hose clamps or replace damaged hoses.
• If the radiator is leaking, replace it with a new unit.
• Refill the coolant reservoir with the appropriate type of coolant as per the manufacturer specifications.

4. Check and Repair Exhaust System

• Inspect the exhaust pipes and muffler for any holes or corrosion.
• If leaks are found, replace the affected sections of the exhaust.
• Ensure all connections are tight and free of rust.

5. Clean HVAC System

• Remove any debris or leaves from the HVAC intake area.
• If mold is suspected, use an HVAC cleaner spray in the air intake ducts.
• Run the HVAC system on high to distribute the cleaner and eliminate any odors.
