Solution

1. Preparation

Gather necessary tools and materials: a hose, flashlight, dry cloths, and a bucket for collecting water.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect the Door Seals

Sub-steps:
1. Visually examine all door seals for cracks, tears, or signs of wear.
2. Run your fingers along the seals to feel for any irregularities.
3. Replace any damaged seals with OEM parts if necessary.

3. Check Sunroof Drains

Sub-steps:
1. Open the sunroof fully.
2. Pour a small amount of water into the sunroof channel.
3. Observe if water drains out of the vehicle through the designated drain holes. If not, clear any blockages with compressed air or a flexible wire.

4. Inspect Windshield Seal

Sub-steps:
1. Carefully examine the windshield edges for gaps or deterioration in the sealant.
2. If a gap is found, apply a suitable automotive sealant to reseal the windshield.

5. Conduct a Water Test

Sub-steps:
1. Use a hose to spray water around the vehicle, focusing on the roof, windows, and doors.
2. Have an assistant inside the vehicle to observe any water entering.
3. If leaks are observed, identify the entry point and address it accordingly.

6. Inspect Engine Bay

Sub-steps:
1. Look for any wet spots or signs of coolant leaks around hoses and connections.
2. Tighten any loose hose clamps or replace damaged hoses as needed.
