Can a Car Be Started After the Water Subsides Following Submersion?
2 Answers
After a car has been submerged and the water level has receded, it is temporarily not advisable to start the engine. Below are the specific impacts of a car being flooded: Component Rust: A water-soaked car is highly prone to rusting of body components, which can shorten its lifespan and reduce safety performance. Short Circuit and Stalling: A flooded car can cause corrosion and rusting of the vehicle's wiring, leading to sudden stalling or spontaneous combustion due to short circuits while driving. Repair Costs: The repair costs for a flooded vehicle are extremely high. In cases of severe water ingress, the repair expenses may exceed 50% of the car's original value.
A friend of mine encountered a flood that submerged his car last year. After the water receded, he wanted to start the engine immediately to test it, but the engine was completely destroyed. Upon researching, I learned that water entering the engine cylinders can cause hydro-lock. When you try to start the engine, the piston cannot compress the water, leading to bent or even broken connecting rods. Additionally, the electrical system may short-circuit, requiring major repairs. I suggest not starting the car immediately after the water recedes. First, check the waterline height—if it's above the dashboard, major repairs are almost certain. Calling a tow truck to take the car to a repair shop for inspection is crucial. Technicians will drain the oil and water, and test the battery and computer board. This not only prevents more severe damage but also saves on costly repairs, as the entire system needs cleaning and part replacements. Remember to take photos for insurance claims, and avoid causing greater losses by acting hastily.
