Tools Required: Smoke machine, flashlight, hose clamps
Conduct a smoke test to identify any vacuum leaks in the intake system.
If leaks are found, replace or repair damaged hoses and connections.
Reconnect any disconnected hoses and clamps securely.

3. Replace or Clean Air Filter

Tools Required: Screwdriver (if applicable), replacement air filter
Remove the air cleaner cover by unscrewing or unclipping it.
Take out the air filter and inspect it for dirt or damage.
If dirty, clean it if reusable, or replace it with a new filter.
Reassemble the air cleaner cover securely.

4. Inspect and Repair Exhaust System

Tools Required: Jack and jack stands, wrench set
Raise the vehicle and inspect the exhaust system for any visible leaks or damage.
Tighten loose connections and replace any corroded or damaged sections of the exhaust pipe.
Check for proper sealing at exhaust manifold and gaskets.

5. Check Serpentine Belt and Tensioner

Tools Required: Socket set, belt tension gauge
Inspect the serpentine belt for cracks, fraying, or signs of wear.
Use a belt tension gauge to check the tension; replace the belt if it is loose or damaged.
Replace the tensioner if it does not maintain proper tension on the belt.
