Can a Second Engine Start After Water Immersion Be Detected?
1 Answers
After a vehicle has been submerged in water, it is possible to detect whether a second engine start has occurred. Insurance companies will dismantle the engine for inspection. Following a second start, water stains will be present on the intake grille and intake tract, and there will be sediment accumulation below the intake housing. Additionally, the originally smooth cylinder walls will show scratches, the engine oil will contain impurities, and the crankshaft connecting rods will exhibit rust. The issue of a second engine start is not explicitly addressed in the commercial auto insurance laws. However, most insurance companies follow the practice of either denying claims or applying partial exemptions for damages resulting from a second start after water immersion. The rationale is that stalling during water immersion is highly likely due to water entering the engine, and a second start constitutes human-induced damage. Self-rescue measures for a water-submerged vehicle include: If the water level has not risen above the exhaust pipe, the engine can be started normally, and the vehicle should be driven away promptly. If the water has just reached the chassis but has not entered the cabin, the vehicle can be powered on and pushed away. If water has already entered the cabin, do not attempt to save the vehicle due to the risk of electric shock. In such cases, the driver should immediately call for emergency assistance.
