What are the symptoms of water in a car?
3 Answers
Here is an introduction to the symptoms related to water ingress in a vehicle: 1. Engine stalling while driving: Due to water entering the engine air filter element, the intake resistance increases and water enters the combustion chamber, preventing the spark plugs from igniting. Additionally, water entering the distributor cap causes the distributor to lose its normal ignition function, resulting in the car stalling while driving. Many novice drivers may panic and attempt to restart the engine, which can easily lead to a blown engine. 2. Overheated breather pipe: Another scenario is water entering the crankcase. Theoretically, if water enters the crankcase, it should also enter the cylinders. However, if only a small amount enters the crankcase and not the cylinders, it can freeze in winter, blocking the oil passages, or disrupt lubrication in summer, leading to overheating.
I've been driving for twenty years, and the time my car got flooded is the most memorable: first, there was a musty smell as unpleasant as wet socks, the carpets always felt damp, especially after rain. When I turned on the AC, the air from the vents was humid, and the windows fogged up, making it hard to see the road. The stereo started acting up, sometimes working, sometimes not, and the lights flickered when turned on, making night driving particularly dangerous. The engine stuttered when starting, like it couldn't catch its breath. Later, when I took it in for repairs, I found out the drain holes were clogged, water had accumulated inside, and there was quite a bit of mold growing. Since then, whenever there's heavy rain, I check the window seals to prevent problems before they happen, otherwise, corroded electrical circuits can cost a fortune to fix.
As someone who frequently repairs cars, I've seen plenty of water ingress symptoms. Electrical components are usually the first to fail: power windows get stuck, dashboard warning lights flash like party decorations. Carpets stay soggy, sloshing sounds come from underneath when driving, and a persistent mildew odor fills the air. Water in the brake system makes pedals feel spongy, and illuminated ABS lights demand caution. Hydrolocked engines hiccup at idle; severe cases cause stalling. I recommend checking floor mats immediately after rain and clearing door frame drain holes. Delayed repairs lead to radiator rust and leaks - repairs cost thousands minimum, not to mention safety risks.
