How to Solve Water Ingress in a Car?

[Guy]

Here are the solutions for water ingress in a car: 1. Turn off the ignition switch: If water ingress is detected while driving, it is recommended to turn off the ignition switch and avoid attempting to restart the engine. The car should be slowly moved to a dry area. 2. Drain the water inside the cabin: Heavy rain is common in summer. If water is found inside the car cabin, it should be drained promptly to prevent damage to the interior. 3. Remove water from the engine: The engine is the power source of the car. If water is found inside the engine, the first step is to remove the spark plugs to help keep the engine system dry. 4. Maintain the chassis: The chassis is the lowest part of the car. If the car has been driven through water, the chassis should be inspected and maintained promptly to drain any water and apply lubricant.

I was so frantic when my car got flooded last time! Immediately turned off the engine and pulled out the keys - if water gets into the engine, it's totaled. Before calling the tow truck, first aid is crucial. Stuff towels into door gaps to absorb water, use a vacuum to suck out water under the seats. On sunny days, leave doors wide open for sun drying - remember to remove floor mats to dry, otherwise the mildew smell from wet carpets can be overwhelming. The trickiest part is electrical issues - if water gets into the dashboard, you'll need to disassemble it to check wiring connections, best handled professionally with drying equipment at a repair shop. Oh, and never park in low-lying areas during rain - replacing door seals annually is particularly important.

Water in the car is no small matter. That time after the rain, I found the footwell completely flooded. Immediately disconnect the battery to prevent short circuits, then lift the carpet to squeeze out water and repeatedly press with dry towels to absorb moisture. Seat cushions need to be removed and air-dried for three days, otherwise internal dampness will corrode the metal frame. Remember to unclog door drain holes with wire—they often get blocked by leaves causing water backup. If water depth exceeds half the tire height, never start the engine; contact a repair shop directly to lift and inspect the chassis. Such repairs may cost around two thousand, but it's far cheaper than an engine overhaul.

Forgot to close the window and got caught in a heavy rain, the car was like a fish tank. Immediately used a plastic basin to scoop out the accumulated water, turned the AC to maximum heat and dried it for three hours. Focused on cleaning the gaps in the dashboard, using cotton swabs dipped in alcohol to wipe the contacts to prevent oxidation. The audio system is the most vulnerable, so I disassembled the head unit and used a hair dryer on the cool setting to blow the circuit board. Later found that the soundproofing foam inside the door panels was still damp, so I went to a modification shop to replace it with new foam. It's recommended to keep a car water-absorbing pad handy, check the sunroof drainage pipes weekly during the rainy season, and replace rubber parts immediately if they show signs of aging.
