Can the Engine Be Restarted After Water Intake?

[Adaline]

After a vehicle has been submerged in water, it is strictly prohibited to attempt a restart. The reasons are as follows: 1. Damage to the Engine Block: If the vehicle stalls during water submersion, it indicates that water has entered the engine. Since water is incompressible, the piston cannot reach its original top dead center position, resulting in a shorter piston stroke and a noticeable downward shift in the top dead center position. Attempting to restart the engine under these conditions can cause the piston connecting rod to bend, and in severe cases, damage the engine block, leading to irreparable harm. 2. No Compensation from Insurance Companies: Any damage caused by restarting the engine after water intake will not be covered by insurance. Moreover, attempting to restart the engine after water intake is a serious violation of insurance claim principles, making the claim ineligible. In such situations, the first course of action should be to push the vehicle out of the water, then call for roadside assistance or contact a nearby repair station to have the vehicle towed away for inspection and repairs.
