Why Can't You Start the Engine Again After Driving Through Water?

[EvangelineLee]

Because restarting the engine can cause damage, and insurance companies will not cover the cost if you attempt to restart it. Here are the details: 1. Driving Through Water: If water is sucked into the cylinders while driving through water, it can cause the engine to stall. If you then force the starter to turn the engine, the pistons will attempt to compress the water. Since water cannot be compressed, this will result in damage to the engine's connecting rods and crankshaft, requiring extensive engine disassembly for repairs. 2. Stalling: In many cases, a car stalling while driving through water is not due to water entering the engine but rather because the increased resistance from the water causes the engine to lose power and stall. To check if water has entered the engine, simply open the air filter cover and inspect whether the filter is wet. If the filter is wet, it’s highly likely that water has entered the engine.
