Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the 12V battery for safety.

2. Inspect and Repair Air Intake System

Remove the engine cover (if applicable) using a socket set.
Inspect the intake hoses and connections for cracks or loose fittings.
Tighten any loose clamps and replace any damaged hoses with OEM parts.

3. Check and Repair Cooling System

Inspect all hoses leading to and from the radiator for signs of wear or leaks.
Replace any damaged hoses or connections found during inspection.
Refill coolant as necessary with the manufacturer-recommended fluid.

4. HVAC System Inspection

Remove the cabin air filter access panel and inspect the filter for obstructions.
Replace the cabin air filter if it is clogged or dirty.
Ensure that the HVAC system operates normally after reassembly.
