Why Is There Water Sound in the Car After Rain?
2 Answers
The reasons for water sound in the car after rain are as follows: 1. Water accumulation inside the door is caused by excessive dust buildup inside the door or small advertisement cards left inside, which block the drainage holes at the bottom of the door. 2. Water accumulation below the front windshield usually occurs after typhoon weather. 3. Excessive dust buildup can block the drainage pipes. 4. The drainage pipes may have aged or cracked. Below are precautions for driving in rainy weather: 1. Avoid getting stuck in water: When driving through areas with accumulated water, such as under overpasses or deep tunnel roads, first stop to check the water depth. If the water exceeds the exhaust pipe, it can cause the vehicle to stall; if it exceeds the bumper, water may enter the car. Avoid driving at high speed through puddles or ditches, as this can cause splashing, increasing the actual water depth and risking engine flooding. 2. Do not drive recklessly: In heavy rain with poor visibility, do not take risks. Stop promptly and turn on the parking lights. On highways, quickly move to a service area or exit the highway. 3. Do not reduce tire pressure in rainy weather: When braking in the rain, sufficient pressure is needed to push the water away from between the tires and the road to stop the car safely. Increasing the tire contact area reduces the pressure per unit area on the ground, weakening braking power and making it harder to expel water from between the tires and the road, thus increasing the stopping distance.
I've encountered the issue of hearing water sloshing sounds in the car after rain several times. The most common cause is clogged sunroof drainage tubes. When rainwater can't drain properly, it accumulates in the roof panel and creates splashing noises. Back when I drove my old car, it would make loud sloshing sounds whenever it rained. Later I discovered the sunroof edge drainage holes were completely blocked with leaves and mud. Simply using a thin wire or straw to clear them fixed the problem. Sometimes the drainage holes at the bottom of car doors also get clogged, allowing water to accumulate and slosh inside the door panels. If left untreated, excessive water may leak into the car interior, soaking the carpets and potentially causing mold or body rust over time. Faulty AC drainage tubes are another frequent culprit - located beneath the driver's seat, when clogged they cause dripping sounds as water accumulates. I recommend promptly checking and clearing all drainage systems after heavy rain, and routinely cleaning them during car washes as preventive maintenance.
