What to Do If Water Enters the Car?

[CollinLynn]

Immediately inspect the engine. First, check whether water has entered the engine cylinders, as this can cause the connecting rods to bend and damage the engine. Check if water has entered the transmission. Water in the transmission can cause the gear oil to deteriorate, leading to gear wear. Inspect the brake fluid and the four-wheel brakes. Water in the brake fluid can cause it to deteriorate, resulting in brake failure.

It's really frustrating when a car gets flooded. I once experienced a situation where the water level during a heavy rainstorm rose above the exhaust pipe. My first reaction was to definitely not start the engine again—immediately turn it off, shift to neutral, and calling a tow truck is the most reliable option. Repairing a water-logged engine can cost tens of thousands, and that's definitely not money you want to waste. I usually keep a window-breaking hammer in the car, which can be a lifesaver if the electronic window locks fail. Additionally, checking the car's undercarriage shouldn't be taken lightly. Seat foam that's been soaked and then dried can still grow mold, so it's best to remove and thoroughly dry it. Electrical connectors also need to be dried one by one with a hair dryer to prevent oxidation, otherwise short circuits later on can be even more troublesome.

Last time during the typhoon, when I went to drive, I found the cabin carpet soaked with about three fingers' depth of water. I was really stunned at that moment. Quickly used dry towels to soak up the water for half an hour, then went home to use a hair dryer on the circuit plugs. Remember to dry all USB ports with cotton swabs, otherwise charging your phone might blow a fuse. Recently, I also bought a bottle of circuit protection spray to prevent rust when applied to battery terminals. Actually, clogged sunroof drain tubes are the most common issue that people often neglect to maintain. It's recommended to use an air gun to blow out the drainage holes every quarter, which can save a lot on repair costs.

Having seen too many cases of flooded vehicle repairs, the treatment varies greatly depending on the extent of water damage. For a car that has just been flooded, immediately disconnect the negative terminal of the battery to prevent electrical short circuits and ECU burnout. When draining water, don't just focus on visible areas; remove the inner door panel's waterproof membrane, as accumulated water there can corrode the window lift motor. If the car was submerged in saltwater, it's even more troublesome—use white vinegar to clean salt deposits from wire connectors, otherwise, they will definitely develop verdigris within six months. It's recommended to replace the chassis bearings entirely, as sand and silt entering the bearing gaps will cause abnormal noises while driving.

Last time after driving through a flooded section, I found my trunk had turned into a fish tank, with the spare tire well holding nearly half a basin of water. Upon inspection, it turned out to be due to aged sealing strips around the taillights allowing water seepage. A circle of silicone sealant fixed the issue. A reminder to everyone: after water immersion, the AC system requires deep cleaning - a moldy evaporator will blow out bacteria. The dashboard also needs to be disassembled for inspection, as water in the pointer motor can cause it to stick. Don't forget to change the transmission fluid either, as water-contaminated oil significantly loses lubricity. Generally, after repairing a water-damaged vehicle, it's advisable to perform a wheel alignment, as soaked suspensions are prone to deformation.

It's best to conduct a comprehensive vehicle inspection before the rainy season, especially for cars over five years old. Personally, I apply a layer of rubber protectant on the door seals to prevent aging and use a wire to clear the drainage holes. When encountering deep water areas, drive slowly at a steady speed and avoid sudden braking to prevent water surges from entering the exhaust pipe. If water does enter, take photos for evidence first and then contact the insurance company; filing a claim within 24 hours ensures the smoothest process. Lastly, it's recommended to install an engine guard plate, which can block most splashing water—this small investment can save a lot of trouble.
