Where Should Water Not Enter a Car
1 Answers
Three areas in a car that are most vulnerable to water ingress: Area 1: Sunroof The sunroof is located on the roof. When rainwater flows onto it, the water will run along the sunroof channel towards the drain holes, then be discharged through drainage tubes typically hidden inside the A and C pillars. If the sunroof drain holes become clogged, accumulated water may overflow into the car interior. Another potential issue is the sealing rubber gasket. Area 2: Door During rainy weather, window glass and sealing rubber strips usually do a good job of keeping rainwater out. Water that seeps through gaps will enter the door cavity and flow out through drainage holes at the bottom of the door. However, if the door develops the same problems as the sunroof—clogged drainage holes, aged or loose sealing strips, or damaged rubber gaskets at the bottom drainage holes—it will prevent water from draining properly, allowing it to flow into the car floor and become a persistent nuisance. Area 3: Chassis The car chassis generally has drainage holes to allow water to escape after driving through water. If these drainage holes are blocked by debris or if the rubber gaskets around them have aged and fallen off, water can easily seep in after driving through water. Therefore, after driving through water, it's advisable to promptly lift the floor mats to check for any accumulated water. If found, it should be dried immediately, and the car chassis should be dehumidified.
