🌊 Immediate Steps to Take When Your Car Gets Flooded
1. Do Not Start the Car
The first instinct of most car owners is to turn the ignition on. ❌ This is the biggest mistake.
If water has entered the engine, starting the car can cause Hydrolock – a condition where water damages the piston and cylinder.
Wait until the car is fully inspected by a mechanic.
2. Disconnect the Battery
Water and electricity are a dangerous combination. If it is safe to access your car:
Disconnect the negative terminal of the battery.
This prevents short-circuits and protects the ECU (Electronic Control Unit).
3. Check Water Level Marks
Look at how high the water has risen:
If the water only touched the floor mats, the damage may be limited to interiors.
If water reached dashboard level or higher, engine and electronics might be heavily damaged.
4. Remove Water and Moisture Quickly
Use a vacuum or absorbent towels to remove standing water.
Keep car doors, windows, and boot open in sunlight for ventilation.
Use fans or dehumidifiers if available to prevent mold.
