What Causes Car Leakage?
2 Answers
The reasons for car leakage are: 1. Door leakage: usually caused by aging window waterproof strips or blocked door drainage holes; 2. Sunroof leakage: in most cases, it is due to clogged sunroof drainage holes; 3. Water accumulation in the trunk: generally caused by poor sealing of the trunk seal or poor sealing of the tail light seal; 4. A drainage hole on the fuel tank cap, as the fuel tank opening faces upwards, which can easily lead to water accumulation on the fuel tank cap. If your car is leaking, you can only go to a 4S store or a professional auto repair shop for treatment, letting the staff fix it. You can first clean the accumulated water inside the car with a dry towel or a water scooping tool, then repair the leaking part.
My car has leaked several times, mainly due to gaps in the body. The most common causes are an improperly closed sunroof or clogged drainage channels, which can lead to water accumulation and leakage inside the car during rain. When the door sealing rubber strips age and harden, water can seep through the gaps if the seal isn’t tight. Once, while driving on the highway during a heavy rainstorm, the car interior was flooded—turns out the sunroof drain tube was completely blocked by leaves. Cleaning the drainage channels is simple; just use a thin wire to unclog them. If the leak occurs in the engine compartment, it might be due to a cracked radiator or hose, and a loss of coolant can cause the engine to overheat, requiring immediate inspection. It’s advisable to check the sealing strips monthly and clear all drainage passages before the rainy season to prevent moldy interiors or electrical shorts. In short, addressing small issues promptly can save you from bigger problems.
