Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool completely before starting work.

2. Inspect Cooling System

Sub-step 1: Remove the engine cover (if applicable) using a socket set.
Sub-step 2: Visually inspect all hoses, clamps, and the radiator for signs of coolant leaks (dampness, corrosion).
Sub-step 3: If leaks are visible, replace the damaged hoses or clamps as needed.

3. Pressure Test Cooling System

Sub-step 1: Connect a cooling system pressure tester to the radiator cap opening.
Sub-step 2: Pump the tester to the recommended pressure (usually around 15-20 psi).
Sub-step 3: Observe if the pressure drops, indicating a leak. Check all areas for fluid escaping.

4. Inspect Cabin Area

Sub-step 1: Remove the cabin air filter cover and filter to check for moisture.
Sub-step 2: Inspect the area around the windshield for cracks or improper sealing.
Sub-step 3: If leaks are found, reseal the windshield or replace weather stripping as necessary.

5. Test Air Conditioning System

Sub-step 1: Run the air conditioning and check for excessive water drainage under the vehicle.
Sub-step 2: Ensure the drain tube is not clogged or damaged.
