Will restarting a car engine after water immersion damage it?
1 Answers
Restarting a car after water immersion can damage the engine. If the car stalls after driving through water and water enters the engine, forcibly restarting it can cause the engine connecting rod to bend. A bent connecting rod can damage the engine block and crankshaft, causing significant harm to the engine, and in severe cases, may lead to engine failure. Below is more information about driving through water: Reasons for stalling after driving through water: The high-voltage ignition system may become damp or short-circuited due to water ingress, causing the engine to stall. This is a common occurrence, usually caused by splashing water. Water entering the exhaust pipe, which is positioned low on the car, can submerge the exhaust outlet, preventing exhaust flow and causing the engine to stall. What to do if the car stalls after driving through water: Do not attempt to restart the engine if the car stalls after driving through water, as this can cause severe damage or even total engine failure. Stay calm, turn off the ignition immediately, and avoid trying to start the engine. The car should be towed to a repair shop promptly to prevent further damage. After driving through water, it is advisable to inspect the engine compartment, air intake, wheels, brake discs, exhaust pipe, and carbon canister for any debris that may affect driving safety.
