Haval H6 sunroof drainage slots are usually located inside the A-pillars and C-pillars of the vehicle. There is a circular rubber plug, with one on each side of the rear longitudinal beams, similar to the front ones. When water enters the sunroof channel, it flows to the drain holes and then exits the vehicle through the drainage pipes. 1. Drain hole leakage: Sunroof drain holes are generally hidden, and their positions vary depending on the car model. Even professionals at 4S shops can easily overlook them during routine maintenance. If the sunroof leaks, check whether the drain holes are clogged with dust. There are no special requirements for daily maintenance of the car sunroof, just regularly check the surrounding seals for damage and the lubrication condition of the tracks. Normally, you need to check the cause of the leakage. 2. Debris: The sunroof outlet is blocked by debris, preventing rainwater from draining out and gradually seeping into the car. Damaged sunroof seals can lead to poor edge sealing, allowing rainwater to enter the car. Gaps in the sunroof frame can also cause rainwater to seep in, which usually occurs during heavy rain.

Every time I take my Haval H6 to the car wash, I make it a habit to check the sunroof drainage holes. Those little guys are usually hidden in the four corners of the sunroof on the roof. Just open the sunroof, and you can see small holes in the gaps. The front two are near the windshield, and the back two are near the rear of the car. The tubes run all the way to the wheel arches or the door edges to drain water. Once they get clogged, it's easy for water to leak into the cabin, wetting the carpets or the headliner, which is quite annoying. I’m used to cleaning them every six months—just blow compressed air into the holes or poke them with a thin wire. After years of driving, I’ve found this issue is actually quite common, and early prevention avoids trouble. I remember last year my friend’s car had to spend thousands on interior repairs just because of clogged drainage holes.

My Haval H6 once experienced a water leakage incident. After a rainy day, I found the interior was damp, and upon inspection, I discovered the sunroof drainage holes were clogged with leaves. The holes are located at the edges of the sunroof, especially noticeable at the front on both sides. Later, I found a cleaning method myself: open the car door and check the drainage outlets near the wheel arches to ensure they are flowing smoothly. Paying a little more attention usually makes driving much more worry-free. Haval's drainage system design isn't overly complicated, but regular checks can prevent small issues from becoming big problems. Like now, I clean it every quarter, saving a lot on repair costs.

When I first got my Haval H6 and didn't know much about cars, it took me some time to figure out the location of the sunroof drainage holes. Actually, you just need to open the roof sunroof and look for small holes in the corners, with both front and rear having them. At first, it seemed a bit tricky to find, but after trying to clean them with a thin brush or cotton swab a few times, I got the hang of it. Now, every time I park under trees, I simply check to make sure the holes aren't blocked. It's pretty easy to maintain.
